Picture Player / Plugin Workshop

[hari]

Notes from tschak's brainstorming and tutorial:

[2008/03/21 00:01:44] <TSCHAK> i'll whip together a gallery viewer
[2008/03/21 00:02:07] <hari> TSCHAK: cool
[2008/03/21 00:02:14] <hari> TSCHAK: anything i can assist with?
[2008/03/21 00:02:33] <hari> thats one of the features my SO is begging for
[2008/03/21 00:02:47] <TSCHAK> hari, well.. this is my plan of attack:
[2008/03/21 00:03:03] <TSCHAK> hari, (1) look at the Photo_Screensaver Template and code... figure out what we can and can't use
[2008/03/21 00:04:49] <TSCHAK> hari, then (2) create the DCE for the plugin and player..
[2008/03/21 00:05:11] <TSCHAK> hari, then.. (3) try to figure out if there's anything we need to circumvent at the Media Plugin
[2008/03/21 00:05:26] <TSCHAK> hari, then (4) implement the first pass, grafting code from photo screen saver into the new plugin
[2008/03/21 00:05:55] <hari> TSCHAK: just looking at (1)
[2008/03/21 00:05:59] <TSCHAK> hari, basically (3) is going to be one of the hairier parts, because we need to figure out WHAT in the media plugin is hard coded with respect to photos
[2008/03/21 00:06:29] <TSCHAK> I dread (3)
[2008/03/21 00:06:31] <TSCHAK> ;-)
[2008/03/21 00:14:40] <TSCHAK> hari, okay, making a new media plugin, Pictures Plugin
[2008/03/21 00:15:53] <TSCHAK> basically, we need to ...get the view/visualization stuff
[2008/03/21 00:15:57] <TSCHAK> and rip it out of photo screensaver
[2008/03/21 00:16:50] <TSCHAK> hopefully this can be a partial cut and paste job
[2008/03/21 00:17:11] <TSCHAK> the first bit, is getting the DCERouter Plugin fleshed out
[2008/03/21 00:18:03] <TSCHAK> hari, i am using the Xine_Plugin as my visual template
[2008/03/21 00:18:18] <TSCHAK> hari, at the very least, you have to implement create stream, play stream, and stop stream
[2008/03/21 00:21:20] <TSCHAK> hari, pictures_plugin has a device category of media player plugins < plugins for the DCE router
[2008/03/21 00:22:41] <hari> so i assume that builds a playlist from the datagrid and then tell the device to display the items..
[2008/03/21 00:23:09] <TSCHAK> yes, all of that is actually handled by the media plugin
[2008/03/21 00:23:33] <hari> so why do we need a distinct plugin then?
[2008/03/21 00:23:34] <TSCHAK> so for this first pass, i just implement the plugin commands to create the media stream etc.
[2008/03/21 00:23:42] <TSCHAK> because it's a distinct media stream type
[2008/03/21 00:24:06] <hari> so the media plugin abstracts stream types and the distinct plugins handle them?
[2008/03/21 00:24:17] <TSCHAK> well, there's two parts
[2008/03/21 00:24:31] <TSCHAK> (yes, this is gonna take some explaining)
[2008/03/21 00:24:43] <TSCHAK> (I had to figure this all out from scratch)
[2008/03/21 00:24:52] <TSCHAK> there is.. media plugin...
[2008/03/21 00:24:57] * bmac2 is listening intently so maybe he will get a clue on plugins
[2008/03/21 00:25:07] <TSCHAK> media plugin provides all the UI aspects of the media section of the orbiter
[2008/03/21 00:25:16] <TSCHAK> it also provides the base classes for media streams
[2008/03/21 00:25:28] <shaggy71875_lmce> *shaggy listens to the wise ones as well
[2008/03/21 00:25:40] <TSCHAK> media streams are basically handle classes, that encapsulate the media url, time code, etc...
[2008/03/21 00:25:51] <hari> k
[2008/03/21 00:26:01] <TSCHAK> and every media stream, has a distinct type
[2008/03/21 00:26:05] <TSCHAK> remember, we're dealing with C++ here...
[2008/03/21 00:26:47] <TSCHAK> and typically every media type has its own plugin... Xine is sort of a swiss army knife
[2008/03/21 00:26:52] <TSCHAK> because it handles both audio and video
[2008/03/21 00:27:03] <TSCHAK> but that doesn't matter.. .for this discussion, I'll continue
[2008/03/21 00:27:10] <TSCHAK> so....
[2008/03/21 00:27:22] <TSCHAK> there are two different pieces of code we're dealing with here
[2008/03/21 00:27:47] <TSCHAK> the plugin, which runs on the core...which creates our MediaStream subclass (PictureMediaStream)
[2008/03/21 00:27:58] <TSCHAK> and finding all of the Player objects in the house that can handle it
[2008/03/21 00:28:28] <TSCHAK> the plugin part needs to deal with figuring out which players can do what, and therefore what to send...
[2008/03/21 00:28:46] <hari> k
[2008/03/21 00:28:48] <TSCHAK> the OTHER part of the equation
[2008/03/21 00:28:51] <TSCHAK> is the Player
[2008/03/21 00:28:56] <TSCHAK> the Player... is what runs on each media director
[2008/03/21 00:29:09] <TSCHAK> Pictures_Player recieves commands from Pictures_Plugin
[2008/03/21 00:29:18] <TSCHAK> mainly, Play Media, Stop Media etc.
[2008/03/21 00:29:29] <hari> k
[2008/03/21 00:29:36] <hari> how does the datagrid plugin fit into this picture?
[2008/03/21 00:29:37] <TSCHAK> and uses the media stream identifiers and URL etc passed to it from the plugin
[2008/03/21 00:29:40] <TSCHAK> to do what it needs to do to work
[2008/03/21 00:29:50] <TSCHAK> Media_Plugin handles all datagrid interaction
[2008/03/21 00:30:19] <TSCHAK> as such, you don't have to do things like register a datagrid generator, etc...
[2008/03/21 00:30:24] <TSCHAK> all you have to do
[2008/03/21 00:30:31] <TSCHAK> is respond to play media, stop media etc commands
[2008/03/21 00:30:38] <TSCHAK> and media plugin will build and manage your playlists for you
[2008/03/21 00:30:50] <hari> ah, the datagrid stuff is handled at the media plugin level?
[2008/03/21 00:30:55] <hari> k
[2008/03/21 00:30:57] <TSCHAK> you get a metric fuckton of functionality for free
[2008/03/21 00:31:05] <TSCHAK> including the file list
[2008/03/21 00:31:07] <TSCHAK> etc
[2008/03/21 00:31:12] <TSCHAK> all of this is abstracted out
[2008/03/21 00:31:14] <hari> so we don't even have to handle the playlist..
[2008/03/21 00:31:21] <TSCHAK> the only thing we need to deal with
[2008/03/21 00:31:29] <TSCHAK> is the "Jump to Playlist Entry" command
[2008/03/21 00:31:49] <TSCHAK> so if you click a picture entry on the playlist data grid, it will go to the right one
[2008/03/21 00:31:52] <hari> to tell the device which exact item of the playlist to show
[2008/03/21 00:31:55] <TSCHAK> yup
[2008/03/21 00:32:03] <TSCHAK> there are other bits as well that we can investigate
[2008/03/21 00:32:19] <TSCHAK> there are operator overloads with respect to queuing and dequeuing the playlist
[2008/03/21 00:32:20] * bmac2 is still hunting like mad to find these parts of code in the src directory in his code
[2008/03/21 00:32:38] <TSCHAK> bmac2, src/Media_Plugin
[2008/03/21 00:32:43] <bmac2> I am there
[2008/03/21 00:32:45] <TSCHAK> bmac2, and src/Xine_Plugin
[2008/03/21 00:32:49] <TSCHAK> bmac2, and src/Xine_Player
[2008/03/21 00:33:26] <TSCHAK> and there are things we need to override in the media plugin to enable certain bits of functionality

[hari]

[2008/03/21 00:33:29] <TSCHAK> such as ContainsVideo
[2008/03/21 00:33:37] <TSCHAK> which in our case, simply needs to return true;
[2008/03/21 00:33:38] <TSCHAK> why?
[2008/03/21 00:33:43] <TSCHAK> so the photo screensaver will STOP.
[2008/03/21 00:33:48] <hari> so where are the media types defined exactly?
[2008/03/21 00:34:06] <hari> you have made your homework
[2008/03/21 00:34:15] <TSCHAK> well.... this is where things get interesting
[2008/03/21 00:34:28] <TSCHAK> it STARTS, in pluto_main
[2008/03/21 00:34:29] <hari> i assume a bit in sql and a bit in c++
[2008/03/21 00:34:33] <TSCHAK> with MediaType
[2008/03/21 00:34:56] <TSCHAK> do you guys want to jump on conference?
[2008/03/21 00:34:57] <TSCHAK> hehehe
[2008/03/21 00:35:03] <shaggy71875_lmce> yes
[2008/03/21 00:35:07] <hari> |           27 | pluto_HDDVD       | LinuxMCE HD-DVD       |         NULL |        1 | NULL                                                             | videos       |                      0 |    NULL |           0 |                         NULL |     24 |      1860 |    33129 |          0 | 0000-00-00 00:00:00 |         NULL |
[2008/03/21 00:35:27] <TSCHAK> hari, okay, now let's look at that entry
[2008/03/21 00:35:27] <bmac2> ok what file inside the Medai_Plugin is this stuff in?
[2008/03/21 00:35:41] <hari> | PK_MediaType | Define            | Description           | FK_DesignObj | DCEAware | Extensions                                                       | Subdirectory | IsExternalTransmission | FK_Pipe | CanBookmark | EK_AttributeType_DefaultSort | psc_id | psc_batch | psc_user | psc_frozen | psc_mod             | psc_restrict |
[2008/03/21 00:35:43] <bmac2> right now I am looking at the Media_Plugin.cpp
[2008/03/21 00:35:56] <TSCHAK> bmac2, MediaStream.cpp has a lot of stuff that needs to be overridden.
[2008/03/21 00:36:05] <bmac2> k
[2008/03/21 00:36:15] <TSCHAK> hari, okay, PK_MediaType is important, that's our media type definition...
[2008/03/21 00:36:26] <hari> k
[2008/03/21 00:36:36] <bmac2> hari where did that come from?
[2008/03/21 00:36:39] <bmac2> the database?
[2008/03/21 00:36:46] <TSCHAK> bmac2, yes, select * from MediaType
[2008/03/21 00:36:47] <hari> bmac2: pluto_main, Table MediaType
[2008/03/21 00:36:54] <bmac2> k
[2008/03/21 00:36:59] <bmac2> just trying to keep up
[2008/03/21 00:37:01] <TSCHAK> wow, we're going at 5000 miles an hour
[2008/03/21 00:37:38] <hari> whats FK_DesignObj used for? where do i see that on the orbiter?
[2008/03/21 00:37:50] <TSCHAK> ok now, Define.. this creates a constant in Define_MediaType.h that you can reference to get your PK_MediaType
[2008/03/21 00:38:05] <TSCHAK> hari, that's not used at all, notice they're all null?
[2008/03/21 00:38:19] <hari> ah yes, i c
[2008/03/21 00:38:21] <TSCHAK> hari, this database is full of vestige columns
[2008/03/21 00:38:35] <TSCHAK> hari, okay... sooooooooo
[2008/03/21 00:38:35] <hari> TSCHAK: we have sqlCVS schema handling for that
[2008/03/21 00:38:50] <TSCHAK> hari, notice what I said about Define?
[2008/03/21 00:38:54] <hari> yes
[2008/03/21 00:39:02] <TSCHAK> hari, you'll use that all over the code to refer to this media type directly.
[2008/03/21 00:39:03] <hari> thats dcegen'ed i assume?
[2008/03/21 00:39:11] <hari> wrong
[2008/03/21 00:39:11] <TSCHAK> no, that's sql2cpp'ed
[2008/03/21 00:39:13] <hari> sql2cpp'd
[2008/03/21 00:39:14] <hari> yes
[2008/03/21 00:39:23] <hari> so it ends up in which file?
[2008/03/21 00:39:29] <hari> Define_MediaType.h?
[2008/03/21 00:39:30] <TSCHAK> Define_MediaType.h
[2008/03/21 00:39:31] * bmac2 wonders if shaggy71875_lmce is as lost as he is right now
[2008/03/21 00:40:00] <TSCHAK> if you look there, you'll see there are ints that match the PK_MediaTypes in question
[2008/03/21 00:40:02] <shaggy71875_lmce> yes bmac
[2008/03/21 00:40:11] <hari> so that gives:
[2008/03/21 00:40:13] <hari> #define MEDIATYPE_pluto_HDDVD_CONST 27
[2008/03/21 00:40:52] <TSCHAK> hari, okay, so that's define... the other major pieces are... Subdirectory
[2008/03/21 00:40:53] <hari> so it simply appends the define field to MEDIATYPE_
[2008/03/21 00:40:58] <TSCHAK> yup
[2008/03/21 00:41:14] <TSCHAK> Subdirectory is used by UpdateMedia to crawl for your media type in LMCE directory structure
[2008/03/21 00:41:54] <shaggy71875_lmce> besides BMAC if you cant break it while playing with it what fun is it anyway
[2008/03/21 00:42:16] <TSCHAK> Extensions is used to tell updatemedia what extensions to crawl for
[2008/03/21 00:42:23] <hari> i see:
[2008/03/21 00:42:24] <TSCHAK> DCEAware needs to be set to 1
[2008/03/21 00:42:30] <hari>  7 | pluto_Pictures    | LinuxMCE Pictures     |         NULL |        1 | jpg,bmp,png,gif,tif
[2008/03/21 00:42:31] <bmac2> so we need lots of extensions
[2008/03/21 00:43:25] <bmac2> some windows downloads caps the jpg and makes linux mad if you don't specify
[2008/03/21 00:43:38] <TSCHAK> and EK_AttributeType_DefaultSort corresponds to the corresponding table in pluto_meida
[2008/03/21 00:44:03] <hari> so there is an AttributeType table i assume
[2008/03/21 00:44:12] <TSCHAK> in our case, that's 13
[2008/03/21 00:44:18] <TSCHAK> hari, yes, in pluto_media
[2008/03/21 00:44:26] <TSCHAK> hari, 13 = Filename
[2008/03/21 00:44:30] <shaggy71875_lmce> does that mean it will crawl all shares/devices on network for those files and list them in pictures
[2008/03/21 00:44:34] <TSCHAK> so defautl Sort by Filename
[2008/03/21 00:44:40] <TSCHAK> shaggy71875_lmce, normally yes
[2008/03/21 00:44:57] <shaggy71875_lmce> thats why all my windows junk showes up
[2008/03/21 00:44:58] <TSCHAK> shaggy71875_lmce, however, UpdateMedia has a hard-coded bit of logic that prevents pictrues from being sought in ANYTHING other than LMCE's directory structure
[2008/03/21 00:45:00] <hari> err, 13 = Title
[2008/03/21 00:45:04] @ seth|work joined channel #linuxmce
[2008/03/21 00:45:08] <TSCHAK> hari, oh yes, sorry, Title...
[2008/03/21 00:45:12] <hari> hehe
[2008/03/21 00:45:21] <TSCHAK> hari, if no other attributes are set, updatemedia sets title to filename
[2008/03/21 00:45:36] <TSCHAK> hari, so that's the first bit
[2008/03/21 00:45:39] <TSCHAK> now
[2008/03/21 00:46:08] <TSCHAK> we go to MediaType_DesignObj;
[2008/03/21 00:46:38] <TSCHAK> I'm trying to do a brain dump!
[2008/03/21 00:46:52] <bmac2> ok TSCHAK where is mediatype_designobj?
[2008/03/21 00:46:56] <bmac2> can't find that file
[2008/03/21 00:47:19] <TSCHAK> that's another database table
[2008/03/21 00:47:19] <hari> bmac2: pluto_main table
[2008/03/21 00:47:19] <hari> *databae
[2008/03/21 00:47:19] <TSCHAK> select * from MediaType_DesignObj;
[2008/03/21 00:47:19] <bmac2> k
[2008/03/21 00:47:19] <TSCHAK> in pluto_main
[2008/03/21 00:47:24] <bmac2> not in my database so just have to listen
[2008/03/21 00:47:30] <TSCHAK> it's there
[2008/03/21 00:47:31] <TSCHAK> i promise
[2008/03/21 00:47:31] <TSCHAK> :-)
[2008/03/21 00:47:40] <TSCHAK> you wouldn't be seeing any media if it wasn't.
[2008/03/21 00:47:46] <hari> bmac2: did you do a "use pluto_main" in mysql?
[2008/03/21 00:47:48] <shaggy71875_lmce> kk
[2008/03/21 00:47:53] <bmac2> no
[2008/03/21 00:47:54] <shaggy71875_lmce> dump away
[2008/03/21 00:48:12] <TSCHAK> i would suggest keeping a mysql window open
[2008/03/21 00:48:16] <hari> so do sth like sudo mysql
[2008/03/21 00:48:16] <bmac2> I am just listending and looking at the C code
[2008/03/21 00:48:21] <bmac2> k
[2008/03/21 00:48:23] <TSCHAK> i will be jumping bakc and forth between the database and the code
[2008/03/21 00:48:25] <TSCHAK> both are important
[2008/03/21 00:50:00] <bmac2> ok did a use pluto_main;
[2008/03/21 00:50:03] <bmac2> what is the next command?
[2008/03/21 00:50:06] <bmac2> to see that table?
[2008/03/21 00:50:09] <TSCHAK> SELECT * from MediaType;
[2008/03/21 00:50:23] <bmac2> k
[2008/03/21 00:50:23] <bmac2> there
[2008/03/21 00:50:27] <bmac2> got a long list
[2008/03/21 00:50:38] <TSCHAK> okay
[2008/03/21 00:50:38] <TSCHAK> now...
[2008/03/21 00:50:42] <TSCHAK> what's happening here
[2008/03/21 00:50:43] <bmac2> I see line 7
[2008/03/21 00:50:51] <bmac2> where it defines the pics
[2008/03/21 00:50:57] * TSCHAK looks
[2008/03/21 00:51:05] <hari> yes
[2008/03/21 00:51:13] <bmac2> pluto_Pictures is line 7
[2008/03/21 00:51:32] <bmac2> line 8 is the missing live radio
[2008/03/21 00:51:33] <bmac2> lol
[2008/03/21 00:51:33] <hari> TSCHAK: what are those np (non pluto?) media types?
[2008/03/21 00:51:40] <TSCHAK> select * from MediaType_DesignObj WHERE FK_MediaType = 7;
[2008/03/21 00:51:50] <TSCHAK> hari, np == Non-Pluto
[2008/03/21 00:52:05] <TSCHAK> hari, those are special types that are defined entirely within the media plugin
[2008/03/21 00:52:11] <TSCHAK> hari, and are handled by the generic media handler
[2008/03/21 00:52:13] <hari> so when we control some device over ir and such?
[2008/03/21 00:52:18] <bmac2> ok got that two lines
[2008/03/21 00:52:19] <TSCHAK> hari, yes.
[2008/03/21 00:52:30] <bmac2> or one line
[2008/03/21 00:52:37] <bmac2> with the titles above
[2008/03/21 00:52:38] <TSCHAK> yeah, i did that so we could zoom in and see
[2008/03/21 00:53:15] <TSCHAK> so we've got this line, you see the media type for it
[2008/03/21 00:53:25] <TSCHAK> but you also see a set of designobjs and screens
[2008/03/21 00:53:40] <bmac2> yes the FK_MediaType is 7
[2008/03/21 00:53:44] <bmac2> which matches the other table
[2008/03/21 00:53:54] <bmac2> where it defines the types by extensions ? right/
[2008/03/21 00:53:58] <TSCHAK> yes
[2008/03/21 00:54:00] <bmac2> k
[2008/03/21 00:54:04] <bmac2> with you so far
[2008/03/21 00:54:08] <TSCHAK> FK == foreign key
[2008/03/21 00:54:11] <TSCHAK> EK == External Key
[2008/03/21 00:54:15] <TSCHAK> PK == Primary Key
[2008/03/21 00:54:28] <TSCHAK> those are sqlcpp and sqlcvs conventions
[2008/03/21 00:54:35] <TSCHAK> so
[2008/03/21 00:54:37] <hari> and you should really follow them
[2008/03/21 00:54:40] <TSCHAK> we have one for FK_Screen
[2008/03/21 00:54:50] <TSCHAK> that means, we have a table called Screen
[2008/03/21 00:54:52] <bmac2> that I am familiar with on keys
[2008/03/21 00:54:55] <bmac2> that i have done
[2008/03/21 00:55:04] <TSCHAK> select * from Screen WHERE PK_Screen  '77';
[2008/03/21 00:55:20] <hari> 77 | Generic DVD Remote | NULL   | Generic DVD Remote |                      NULL |             1 |                 0 |              0 |                  1 |     77 |      1018 |    33129 |          0 | 0000-00-00 00:00:00 |         NULL |
[2008/03/21 00:55:38] <TSCHAK> is it starting to make sense now?
[2008/03/21 00:55:41] <hari> yes
[2008/03/21 00:55:49] <hari> awesome
[2008/03/21 00:55:52] <bmac2> mine failed
[2008/03/21 00:56:02] <TSCHAK> sorry
[2008/03/21 00:56:04] <TSCHAK> forgot the =
[2008/03/21 00:56:05] <TSCHAK> ;-)
[2008/03/21 00:56:11] <TSCHAK> fingers outwunning bwain
[2008/03/21 00:56:14] <bmac2> ok
[2008/03/21 00:56:18] <bmac2> with you I should have caught that
[2008/03/21 00:56:25] <TSCHAK> okay so
[2008/03/21 00:56:32] <bmac2> 77 generic DVD remote?
[2008/03/21 00:56:33] <TSCHAK> that's how you match screens
[2008/03/21 00:56:47] <TSCHAK> yes, now, you know when you regenerate an orbiter
[2008/03/21 00:56:53] <TSCHAK> it says, regenerating screen 46...etc.etc..etc/
[2008/03/21 00:56:54] <TSCHAK> ?
[2008/03/21 00:56:58] <bmac2> yes
[2008/03/21 00:56:58] <hari> yes
[2008/03/21 00:57:03] <TSCHAK> it's going through all those screens in that table
[2008/03/21 00:57:06] <bmac2> those match the PK_Screen
[2008/03/21 00:57:12] <bmac2> numbers in column 1
[2008/03/21 00:57:16] <bmac2> of each table row
[2008/03/21 00:57:16] <TSCHAK> this tells us
[2008/03/21 00:57:26] <TSCHAK> that this media type needs this screen for a STANDARD ORBITER
[2008/03/21 00:57:41] <hari> and what about the JavaMO
[2008/03/21 00:57:44] <TSCHAK> this is the screen used on the nokia pads
[2008/03/21 00:57:46] <TSCHAK> hari, same
[2008/03/21 00:57:51] <TSCHAK> hari, different variation
[2008/03/21 00:57:59] <hari> k
[2008/03/21 00:58:00] <TSCHAK> hari, now we're getting into HADesigner territory
[2008/03/21 00:58:05] <TSCHAK> hari, and we are not gonna go there
[2008/03/21 00:58:18] <TSCHAK> i am keeping this discussion focused.
[2008/03/21 00:58:43] <TSCHAK> now..back to the mediatype_designobj row we had earlier
[2008/03/21 00:58:53] <hari> k
[2008/03/21 00:59:01] <bmac2> with 7 77 and all the nulls
[2008/03/21 00:59:03] <TSCHAK> okay, notice, the FK_DesignObj_Popup ?
[2008/03/21 00:59:12] <bmac2> 4th column
[2008/03/21 00:59:17] <TSCHAK> yes, 4964
[2008/03/21 00:59:18] <bmac2> 4964
[2008/03/21 00:59:27] <TSCHAK> any time you see a DesignObj column
[2008/03/21 00:59:31] <TSCHAK> you can enter this number into HADesigner
[2008/03/21 00:59:36] <TSCHAK> to see that designobj
[2008/03/21 00:59:38] * hari makes notes
[2008/03/21 00:59:40] <TSCHAK> in this case
[2008/03/21 00:59:43] <bmac2> that refers to HADESigner
[2008/03/21 00:59:53] <TSCHAK> this designobj is the left hand menu that's displayed on UI2
[2008/03/21 00:59:58] <hari> so a screen is a collection of designobj?

[hari]

[2008/03/21 01:00:15] <TSCHAK> yes
[2008/03/21 01:00:15] <TSCHAK> quite literally
[2008/03/21 01:00:15] <bmac2> wait
[2008/03/21 01:00:15] <hari> and the designobj itself have layout hints?
[2008/03/21 01:00:15] <bmac2> where do you see UI3
[2008/03/21 01:00:18] <bmac2> UI2
[2008/03/21 01:00:27] <TSCHAK> bmac2, you don't, I'm telling you that.
[2008/03/21 01:00:32] <bmac2> oh ok
[2008/03/21 01:00:33] <TSCHAK> external information
[2008/03/21 01:00:39] <bmac2> I thought the table showed that
[2008/03/21 01:00:50] <bmac2> you just figured that out doing mame
[2008/03/21 01:00:50] <TSCHAK> so basically, if you look at 4964 in HADesigner
[2008/03/21 01:00:51] <bmac2> ok
[2008/03/21 01:00:53] <bmac2> continue
[2008/03/21 01:00:59] <TSCHAK> you see the left hand menu
[2008/03/21 01:01:03] <TSCHAK> which, with video contains
[2008/03/21 01:01:05] <TSCHAK> Aspect Ratio
[2008/03/21 01:01:08] <TSCHAK> Thumbnail
[2008/03/21 01:01:10] <TSCHAK> Random
[2008/03/21 01:01:11] <TSCHAK> etc.etc.etc..
[2008/03/21 01:01:13] <bmac2> k
[2008/03/21 01:01:16] <hari> k
[2008/03/21 01:01:24] <TSCHAK> it's what you see when you mouse over the left hand big square
[2008/03/21 01:01:29] <TSCHAK> make sense?
[2008/03/21 01:01:33] * bmac2 thinks his three dual head machines aren't enough, need a windows box too
[2008/03/21 01:01:35] <bmac2> yes
[2008/03/21 01:01:40] <bmac2> with you on that
[2008/03/21 01:01:43] <shaggy71875_lmce> yikes
[2008/03/21 01:01:45] <TSCHAK> okay...
[2008/03/21 01:01:53] <hari> no
[2008/03/21 01:02:00] <TSCHAK> hari, ?
[2008/03/21 01:02:04] <TSCHAK> hari, question?
[2008/03/21 01:02:11] <hari> left hand big square?
[2008/03/21 01:02:15] <shaggy71875_lmce> okay where are the images it displays located (looks to break somthing
[2008/03/21 01:02:19] <TSCHAK> hari, you don't use UI2 do you?
[2008/03/21 01:02:21] <hari> i do
[2008/03/21 01:02:24] <TSCHAK> hari, it's the left most menu in UI2
[2008/03/21 01:02:34] <TSCHAK> hari, the one that changes with the media
[2008/03/21 01:02:37] <hari> ah
[2008/03/21 01:02:39] <hari> ok
[2008/03/21 01:02:46] <TSCHAK> okay... continuing
[2008/03/21 01:02:56] <TSCHAK> FK_Screen_FileList
[2008/03/21 01:03:07] <TSCHAK> this is what is displayed, when you send an orbiter, a Show File List command
[2008/03/21 01:03:10] <TSCHAK> go ahead and do that
[2008/03/21 01:03:13] <TSCHAK> from the web admin
[2008/03/21 01:03:15] <bmac2> 47
[2008/03/21 01:03:21] <bmac2> is the value for that
[2008/03/21 01:03:24] <TSCHAK> yes.
[2008/03/21 01:03:40] <TSCHAK> if you look at Screen, you'll see it's the file list used for jsut about everything else
[2008/03/21 01:03:56] <TSCHAK> and if you do a Show File List command
[2008/03/21 01:04:00] <TSCHAK> the parameter it asks you for is
[2008/03/21 01:04:02] <TSCHAK> guess what?
[2008/03/21 01:04:04] <TSCHAK> MediaType
[2008/03/21 01:04:06] <hari> do i have to select a file?
[2008/03/21 01:04:11] <hari> in the send command?
[2008/03/21 01:04:16] <bmac2> wait one opening webmin
[2008/03/21 01:04:21] <TSCHAK> hari, no no no
[2008/03/21 01:04:24] <hari> k
[2008/03/21 01:04:32] <TSCHAK> just enter a media type in that list.. in our case, just enter 7
[2008/03/21 01:04:42] <TSCHAK> and you should see "LinuxMCE Pictures"
[2008/03/21 01:04:43] <hari> AWESOME
[2008/03/21 01:04:48] <bmac2> wait
[2008/03/21 01:04:54] <bmac2> where in webmin do I send that command?
[2008/03/21 01:05:01] <TSCHAK> bmac2, Advanced->Devices
[2008/03/21 01:05:02] <hari> bmac2: choose any orbiter
[2008/03/21 01:05:07] <TSCHAK> bmac2, select one of your orbiters
[2008/03/21 01:05:12] <TSCHAK> bmac2, the closest one to you
[2008/03/21 01:05:14] <hari> go to advanced and then select send command to device
[2008/03/21 01:05:18] <TSCHAK> bmac2, such as, i guess.. #20
[2008/03/21 01:05:31] <TSCHAK> bmac2, then you can select Send Command to Device
[2008/03/21 01:05:58] <bmac2> I have no choices from the pulldown
[2008/03/21 01:06:05] <bmac2> once I click on send command
[2008/03/21 01:06:10] <shaggy71875_lmce> advanced >config>devices?
[2008/03/21 01:06:10] <bmac2> my core is all that is r4unning right now
[2008/03/21 01:06:14] <TSCHAK> then you have the wrong device
[2008/03/21 01:06:21] <TSCHAK> choose device #20
[2008/03/21 01:06:23] <TSCHAK> Onscreen ORbiter
[2008/03/21 01:07:02] <hari> http://vt100.at/images/Screenshot-13.png
[2008/03/21 01:07:19] <bmac2> ok now media type?
[2008/03/21 01:07:42] <hari> http://vt100.at/images/Screenshot-14.png
[2008/03/21 01:07:50] <hari> simply enter 7
[2008/03/21 01:07:57] <hari> in the data field
[2008/03/21 01:08:13] <bmac2> wait
[2008/03/21 01:08:17] <bmac2> I am on #20
[2008/03/21 01:08:22] <bmac2> the onscreen orbiter
[2008/03/21 01:08:30] <bmac2> I click on send command at the top
[2008/03/21 01:08:36] <bmac2> I get another window
[2008/03/21 01:08:45] <bmac2> I click on send to this device the command
[2008/03/21 01:08:47] <bmac2> and get a list
[2008/03/21 01:08:52] <bmac2> but I don't see media type
[2008/03/21 01:08:58] <TSCHAK> no no no
[2008/03/21 01:09:00] <TSCHAK> show file list
[2008/03/21 01:09:05] <hari> you have to select "Show File List"
[2008/03/21 01:09:21] <bmac2> got you
[2008/03/21 01:09:22] <hari> as seen on the screenshot
[2008/03/21 01:09:36] <bmac2> so this should show up ON the core screen?
[2008/03/21 01:09:40] <TSCHAK> bmac2, yes
[2008/03/21 01:09:44] <bmac2> k
[2008/03/21 01:09:49] <TSCHAK> bmac2, because you're sending the command to the core's on-screen orbiter
[2008/03/21 01:09:53] <bmac2> ok with you
[2008/03/21 01:09:54] <hari> bmac2: you need a N800
[2008/03/21 01:09:55] <shaggy71875_lmce> got it
[2008/03/21 01:10:04] <bmac2> I need a LOT of hardware
[2008/03/21 01:10:07] <TSCHAK> bmac2, see what happened?
[2008/03/21 01:10:14] <shaggy71875_lmce> send me a n800 lol
[2008/03/21 01:10:17] <bmac2> I understand
[2008/03/21 01:10:22] <TSCHAK> bmac2, okay now
[2008/03/21 01:10:27] <TSCHAK> back to that table row
[2008/03/21 01:16:06] <TSCHAK> MediaType_DesignObj
[2008/03/21 01:16:17] <TSCHAK> we're going to crawl through ALL of it
[2008/03/21 01:16:18] <TSCHAK> we have to
[2008/03/21 01:16:38] <TSCHAK> notice the next one is FK_Screen_OSD ?
[2008/03/21 01:16:48] <hari> null
[2008/03/21 01:16:52] <TSCHAK> yup
[2008/03/21 01:16:55] <TSCHAK> it is
[2008/03/21 01:17:00] <TSCHAK> and we will change that
[2008/03/21 01:17:03] <TSCHAK> but not now
[2008/03/21 01:17:16] <TSCHAK> to compare
[2008/03/21 01:17:18] <bmac2> yes
[2008/03/21 01:17:27] <TSCHAK> look at MediaType 5
[2008/03/21 01:17:35] <TSCHAK> SELECT * from MediaType WHERE PK_MediaType = 5
[2008/03/21 01:17:38] <TSCHAK> this is for Videos
[2008/03/21 01:17:38] <hari> 140
[2008/03/21 01:17:52] <TSCHAK> this is the screen
[2008/03/21 01:17:56] <TSCHAK> that is shown on on-screen orbiters
[2008/03/21 01:17:59] <TSCHAK> any time you see _OSD
[2008/03/21 01:18:03] <TSCHAK> this means On screen orbiter
[2008/03/21 01:18:06] <TSCHAK> 140 in our case
[2008/03/21 01:18:08] <hari> ah
[2008/03/21 01:18:17] <hari> thought it was On Screen Display to overlay sth
[2008/03/21 01:18:19] <TSCHAK> is also what we want
[2008/03/21 01:18:29] <TSCHAK> because in the case of UI1
[2008/03/21 01:18:37] <TSCHAK> it will display the orbiter stuff with the little window
[2008/03/21 01:18:44] <TSCHAK> on the TV
[2008/03/21 01:18:51] <TSCHAK> in the case of UI2, it just displays the whole window
[2008/03/21 01:18:57] <TSCHAK> this is defined in HADesigner
[2008/03/21 01:19:04] <TSCHAK> but am I making sense?
[2008/03/21 01:19:15] <hari> yes
[2008/03/21 01:19:16] <TSCHAK> we'll most likely use Screen 140
[2008/03/21 01:19:25] <bmac2> ok I am not seeing the 140
[2008/03/21 01:19:38] <TSCHAK> bmac SELECT * from MediaType WHERE MediaType = 5
[2008/03/21 01:19:44] <hari> bmac2: the FK_Screen_OSD field
[2008/03/21 01:19:46] <TSCHAK> that's the Video media type
[2008/03/21 01:19:56] <bmac2> I did the select mediatype = 5
[2008/03/21 01:20:05] <bmac2> and got pluto_StoredVideo
[2008/03/21 01:20:08] <TSCHAK> yup
[2008/03/21 01:20:09] <bmac2> as the second line
[2008/03/21 01:20:14] <bmac2> where is the 140?
[2008/03/21 01:20:16] <TSCHAK> we're going to be using the same screen...
[2008/03/21 01:20:20] <TSCHAK> FK_Screen_OSD
[2008/03/21 01:20:28] <hari> mysql> select * from MediaType_DesignObj where FK_Mediatype=5;
[2008/03/21 01:20:41] <hari>  1 |            5 |        70 |               4964 |                 47 |           140 |            50 |               143 |                 224 |                 230 | NULL        |    NULL |         1
[2008/03/21 01:20:54] <hari> 6th field,
[2008/03/21 01:21:35] <hari> TSCHAK: your query missed the _DesignObj
[2008/03/21 01:22:21] <TSCHAK> do SELECT * from Screen WHERE PK_Screen = 140;
[2008/03/21 01:22:33] <TSCHAK> and you'll see, that it is indeed the Full Screen Videos remote
[2008/03/21 01:22:36] <hari> k
[2008/03/21 01:22:43] <hari> yes
[2008/03/21 01:23:00] <TSCHAK> bmac2, make sense?
[2008/03/21 01:23:16] <bmac2> yep
[2008/03/21 01:23:20] <bmac2> if i could spell where
[2008/03/21 01:23:22] <bmac2> lol
[2008/03/21 01:23:22] <TSCHAK> so basically what we are doing at this very moment, is giving information to the media plugin
[2008/03/21 01:23:31] <TSCHAK> as to what remote control screens to use in which cases
[2008/03/21 01:23:51] <TSCHAK> okay, now NEXT screen
[2008/03/21 01:23:55] <TSCHAK> erm, next column
[2008/03/21 01:23:59] <TSCHAK> in MediaType_DesignObj
[2008/03/21 01:24:00] <shaggy71875_lmce> looks to buy a n800
[2008/03/21 01:24:05] <TSCHAK> see FK_Screen_Alt ?
[2008/03/21 01:24:14] <bmac2> 50
[2008/03/21 01:24:37] <TSCHAK> now look up THAT screen
[2008/03/21 01:24:40] <TSCHAK> see what screen that is?
[2008/03/21 01:24:51] <bmac2> dvd menu
[2008/03/21 01:24:53] <TSCHAK> yup
[2008/03/21 01:25:11] <TSCHAK> when you view a DVD menu, what happens is the alt screen is sent, and this screen is sent back
[2008/03/21 01:25:25] <TSCHAK> it provides a way to provide a second UI that can easily be switched by the media plugin
[2008/03/21 01:25:34] <bmac2> k
[2008/03/21 01:25:38] <hari> k
[2008/03/21 01:25:39] <TSCHAK> you can see me use this in mame plugin and mame player
[2008/03/21 01:25:48] <hari> remember that from your screenshots
[2008/03/21 01:25:49] <TSCHAK> but i'll discuss that at some other time
[2008/03/21 01:25:50] <bmac2> ok
[2008/03/21 01:26:05] <TSCHAK> now back again
[2008/03/21 01:26:09] <TSCHAK> FK_Screen_Alt_OSD
[2008/03/21 01:26:12] <TSCHAK> same thing
[2008/03/21 01:26:18] <TSCHAK> except for the on-screen orbiters
[2008/03/21 01:26:59] <bmac2> ohh 143
[2008/03/21 01:27:06] <hari> DVD menu full screen remote
[2008/03/21 01:27:34] <TSCHAK> now, NEXT COLUMN
[2008/03/21 01:27:46] <hari> Speed?
[2008/03/21 01:27:51] <TSCHAK> OSD_Speed and OSD track
[2008/03/21 01:27:52] <bmac2> fk_screen osd speed
[2008/03/21 01:27:59] <bmac2> 224 and 230
[2008/03/21 01:28:00] <TSCHAK> those, are what you get, when you use the gyro remote
[2008/03/21 01:28:32] <TSCHAK> you can define those as needed.. we will leave them as is
[2008/03/21 01:28:53] <TSCHAK> the rest of it doesn't matter
[2008/03/21 01:28:58] <TSCHAK> we can move on
[2008/03/21 01:28:58] <bmac2> k
[2008/03/21 01:29:03] <TSCHAK> but you see
[2008/03/21 01:29:06] <TSCHAK> even at this point
[2008/03/21 01:29:12] <TSCHAK> we have enough to display a file list
[2008/03/21 01:29:15] <TSCHAK> however
[2008/03/21 01:29:22] <TSCHAK> if we actually tried to display something at this point
[2008/03/21 01:29:23] <bmac2> not to display the files
[2008/03/21 01:29:30] <bmac2> just the list
[2008/03/21 01:29:32] <TSCHAK> it would say
[2008/03/21 01:29:33] <TSCHAK> yes
[2008/03/21 01:29:33] <hari> there is no handler for the media type i assume
[2008/03/21 01:29:34] <TSCHAK> it would say
[2008/03/21 01:29:41] <bmac2> unknown file type
[2008/03/21 01:29:45] <TSCHAK> "There is no device in this entertainment area capable of playing it"
[2008/03/21 01:30:00] <TSCHAK> because the system doesn't know, what plugin to pair
[2008/03/21 01:30:05] <bmac2> soo we need to modify player to "play" the files
[2008/03/21 01:30:24] <TSCHAK> we have to tell the system which device template will handle this media type
[2008/03/21 01:30:32] <TSCHAK> on to the next table
[2008/03/21 01:30:39] <hari> TSCHAK: one day we will control all our pictureframes with that
[2008/03/21 01:30:51] <TSCHAK> :-)
[2008/03/21 01:30:51] <bmac2> you and those damn picture frames
[2008/03/21 01:30:52] <bmac2> lol
[2008/03/21 01:30:56] <TSCHAK> i want one too
[2008/03/21 01:30:58] <TSCHAK> ok moving on
[2008/03/21 01:31:07] <shaggy71875_lmce> have one
[2008/03/21 01:31:17] <bmac2> what is the next table?
[2008/03/21 01:31:17] <hari> that was meant seriously
[2008/03/21 01:31:28] <bmac2> I know that is what scares me hari
[2008/03/21 01:31:32] <hari> hehehe
[2008/03/21 01:31:41] <TSCHAK> the next table is DeviceTemplate_MediaType
[2008/03/21 01:31:54] <shaggy71875_lmce> hmm pictureframe that plays video
[2008/03/21 01:32:09] <bmac2> ok 62 rows in that table
[2008/03/21 01:32:12] <bmac2> which row do we need?
[2008/03/21 01:32:20] <TSCHAK>  select * from DeviceTemplate_MediaType WHERE FK_MediaType = '5';
[2008/03/21 01:33:01] <bmac2> ok
[2008/03/21 01:33:05] <bmac2> got the table
[2008/03/21 01:33:07] <TSCHAK> the first row is what we want
[2008/03/21 01:33:07] <bmac2> not what hari has
[2008/03/21 01:33:25] <hari> bmac2: thats some output from "Describe DeviceTEmplate_Mediatype"
[2008/03/21 01:33:56] <TSCHAK> now
[2008/03/21 01:34:02] <TSCHAK> open Device Template 5 in the web admin
[2008/03/21 01:34:07] <TSCHAK> see which one it is?
[2008/03/21 01:34:08] <hari>  4 |                 5 |            5 |                    1 |                1 |              1 |                      1 |                       1 | NULL
[2008/03/21 01:34:41] <hari> xine player
[2008/03/21 01:34:54] <TSCHAK> this becomes the device template of our Picture Player
[2008/03/21 01:35:18] <TSCHAK> and we use the same Can* properties as the video type
[2008/03/21 01:35:24] <TSCHAK> hopefully that's self explanatory so far?
[2008/03/21 01:35:34] <hari> so it implements media player commands..
[2008/03/21 01:36:54] <TSCHAK> bmac2, configuration->Device templates
[2008/03/21 01:37:20] <bmac2> got it
[2008/03/21 01:37:23] <bmac2> xine
[2008/03/21 01:37:33] <bmac2> under media players dce software wrappers
[2008/03/21 01:38:09] <TSCHAK> so the media plugin knows that this media type is associated with this device type
[2008/03/21 01:38:11] <TSCHAK> okay
[2008/03/21 01:38:45] <bmac2> so we need to edit this to add types to it?
[2008/03/21 01:38:55] <bmac2> or is that done in the src code for this?
[2008/03/21 01:38:57] <hari> look at the "Commands section"
[2008/03/21 01:39:17] <TSCHAK> bmac2, we need to make our own new player
[2008/03/21 01:39:20] <hari> and press "edit commands" besides "media player commands"
[2008/03/21 01:39:21] <TSCHAK> bmac2, called Picture Player
[2008/03/21 01:39:22] <bmac2> k
[2008/03/21 01:39:30] <bmac2> but we copy this one? and use xine to show pics?
[2008/03/21 01:39:31] <TSCHAK> bmac2, which duplicates the majority of what's in this
[2008/03/21 01:39:32] <TSCHAK> yes
[2008/03/21 01:39:33] <TSCHAK> no
[2008/03/21 01:39:41] <hari> bmac2: you then see some of the media player commands the xine template implements
[2008/03/21 01:39:45] <TSCHAK> we're doing a new player, grabbing code out of pluto_screen_saver
[2008/03/21 01:39:50] <bmac2> k
[2008/03/21 01:39:52] <bmac2> with you
[2008/03/21 01:39:56] <bmac2> what does flickr use?
[2008/03/21 01:40:01] <bmac2> it shows pics?
[2008/03/21 01:40:11] <TSCHAK> the flickr screensaver is photo screensaver
[2008/03/21 01:40:15] <bmac2> oh ok
[2008/03/21 01:40:15] <TSCHAK> but since this is a new media type
[2008/03/21 01:40:20] <TSCHAK> it needs to implement media player commands
[2008/03/21 01:40:20] <bmac2> kinda
[2008/03/21 01:40:23] <bmac2> ok
[2008/03/21 01:40:28] <bmac2> so part of xine code
[2008/03/21 01:40:35] <bmac2> part of screensaver
[2008/03/21 01:40:42] <bmac2> part of mediatypes in database
[2008/03/21 01:40:47] <bmac2> with you so far
[2008/03/21 01:40:55] <TSCHAK> nothing from xine... we just use this database entry
[2008/03/21 01:40:58] <TSCHAK> as a boilerplate
[2008/03/21 01:41:00] <bmac2> yes
[2008/03/21 01:41:04] <bmac2> to me that is some of it
[2008/03/21 01:41:07] <TSCHAK> ok
[2008/03/21 01:41:08] <bmac2> using it as a template
[2008/03/21 01:41:20] <TSCHAK> so we get a new device template #, and put THAT into the database...
[2008/03/21 01:41:26] <TSCHAK> if you dig around in the template
[2008/03/21 01:41:31] <TSCHAK> you'll see all sorts of commands implemented
[2008/03/21 01:41:38] <bmac2> yes
[2008/03/21 01:41:40] <TSCHAK> stop media, start media, play, etc..etc...
[2008/03/21 01:41:56] <TSCHAK> these are all the bits of C++ codeage that are skeletoned by DCEGen
[2008/03/21 01:41:58] <TSCHAK> that you fill in
[2008/03/21 01:42:08] <bmac2> yes
[2008/03/21 01:42:13] <bmac2> and I see all the stuff
[2008/03/21 01:42:19] <TSCHAK> yup
[2008/03/21 01:42:20] <bmac2> like select highlighted item
[2008/03/21 01:42:24] <bmac2> move select
[2008/03/21 01:42:25] <bmac2> etc
[2008/03/21 01:42:27] <TSCHAK> yup
[2008/03/21 01:42:32] <TSCHAK> tons of possible commands
[2008/03/21 01:42:34] <bmac2> lots and lots and lots of stuff
[2008/03/21 01:42:37] <TSCHAK> you pick what you need
[2008/03/21 01:42:39] <bmac2> k
[2008/03/21 01:42:43] <TSCHAK> okay
[2008/03/21 01:42:46] <TSCHAK> now close those off for now
[2008/03/21 01:43:01] <TSCHAK> now...
[2008/03/21 01:43:08] <TSCHAK> this gives us enough info for the media plugin
[2008/03/21 01:43:11] <TSCHAK> to be able to function
[2008/03/21 01:43:13] <TSCHAK> almost
[2008/03/21 01:43:16] <bmac2> lol
[2008/03/21 01:43:20] <bmac2> and he says almost
[2008/03/21 01:43:20] <TSCHAK> see, we still need to create a media stream
[2008/03/21 01:43:24] <bmac2> I knew that was coming
[2008/03/21 01:43:26] <shaggy71875_lmce> HAH
[2008/03/21 01:43:36] <TSCHAK> the player needs something to play, right?
[2008/03/21 01:43:44] <TSCHAK> okay peoples
[2008/03/21 01:43:46] <bmac2> media stream is in the media_plugin stuff
[2008/03/21 01:43:51] <bmac2> ?
[2008/03/21 01:43:52] <TSCHAK> yup
[2008/03/21 01:43:54] <bmac2> k
[2008/03/21 01:43:56] <bmac2> so I am with you
[2008/03/21 01:43:59] <bmac2> sorta kinda
[2008/03/21 01:44:00] <TSCHAK> do you guys have the latest SVN checkout?
[2008/03/21 01:44:02] <TSCHAK> or recent?
[2008/03/21 01:44:07] <bmac2> mine is a couple of weeks old
[2008/03/21 01:44:08] <TSCHAK> so you can see MAME_Plugin ?
[2008/03/21 01:44:11] <bmac2> yes
[2008/03/21 01:44:12] <bmac2> I got hat

[hari]

[2008/03/21 01:44:15] <hari> yes
[2008/03/21 01:44:24] <TSCHAK> ok, open MAME_Plugin.cpp
[2008/03/21 01:44:36] <TSCHAK> see i told you, we're jumping ALL OVER THE PLACE
[2008/03/21 01:44:42] <TSCHAK> I had to figure _ALL_ this shit out
[2008/03/21 01:44:43] <bmac2> ok got that open in kate
[2008/03/21 01:44:44] <TSCHAK> from scratch
[2008/03/21 01:44:45] <hari> k
[2008/03/21 01:44:59] <bmac2> so far 4 sceens full of windows
[2008/03/21 01:45:00] <hari> TSCHAK: we know, you waste your time with bad assed projects
[2008/03/21 01:45:06] <hari> could not resist...
[2008/03/21 01:45:12] <hari> thank your for explaining all that!!!
[2008/03/21 01:45:28] <bmac2> in yoiur plugin for mame
[2008/03/21 01:45:31] <bmac2> what am I looking for?
[2008/03/21 01:45:35] <TSCHAK> the constructor doesn't really do much
[2008/03/21 01:45:40] <TSCHAK> it just sets up some variables
[2008/03/21 01:45:45] <TSCHAK> and creates mutexes for later
[2008/03/21 01:45:49] <TSCHAK> what we're interested in
[2008/03/21 01:45:51] <hari> so the MediaPlugin is our sister..
[2008/03/21 01:45:59] <TSCHAK> is the Register method
[2008/03/21 01:46:09] <TSCHAK> look at Register
[2008/03/21 01:46:26] <shaggy71875_lmce> what makes you work?
[2008/03/21 01:46:27] <bmac2> the MAME_PlugIN::Register?
[2008/03/21 01:46:29] <hari> vectPK_DeviceTemplate.push_back(DEVICETEMPLATE_MAME_Player_CONST);
[2008/03/21 01:46:43] <hari> m_pMedia_Plugin->RegisterMediaPlugin( this, this, vectPK_DeviceTemplate, true );
[2008/03/21 01:46:48] <TSCHAK>      //<-dceag-reg-b->
[2008/03/21 01:46:48] <TSCHAK> / This function will only be used if this device is loaded into the DCE Router's memory space as a plug-in.  Otherwise Connect() will be called from the main()
[2008/03/21 01:46:58] <TSCHAK> hari, and you just nailed it
[2008/03/21 01:47:02] <hari> bmac2: line 111
[2008/03/21 01:47:08] <TSCHAK> hari, but look at what's happening before that
[2008/03/21 01:47:18] <bmac2> yes I see that
[2008/03/21 01:47:19] <hari> it finds its brothers and sisters
[2008/03/21 01:47:45] <TSCHAK> it finds those sister plugins and creates instances of them
[2008/03/21 01:47:47] <TSCHAK> so you can talk to them
[2008/03/21 01:47:49] <TSCHAK> this is UBER important
[2008/03/21 01:48:05] <hari> i see the registration with the media plugin
[2008/03/21 01:48:05] * bmac2 writes down uber important in notes
[2008/03/21 01:48:06] <TSCHAK> because this way you get access to methods so you can keep orbiter screens in sync etc
[2008/03/21 01:48:10] <hari> but whats the orbiter plugin used for?
[2008/03/21 01:48:23] <hari> to figure out which orbiter should display screens?
[2008/03/21 01:48:27] <TSCHAK> hari, for things like Bind to Media Remote
[2008/03/21 01:48:37] <TSCHAK> hari, so that orbiter remotes can stay in synch
[2008/03/21 01:48:42] <hari> k
[2008/03/21 01:48:45] <bmac2> and it gets the deviceteplates too
[2008/03/21 01:48:51] <bmac2> for the media plugins
[2008/03/21 01:48:55] <TSCHAK> yup
[2008/03/21 01:49:09] <bmac2> k next
[2008/03/21 01:49:19] <hari> and why do you intercept EVENT_Menu_Onscreen_CONST
[2008/03/21 01:49:32] <hari> to handle insert coins?
[2008/03/21 01:49:33] <TSCHAK> why do you think?
[2008/03/21 01:49:36] <TSCHAK> well actually
[2008/03/21 01:49:41] <TSCHAK> this isn't completely implemented yet
[2008/03/21 01:49:47] <TSCHAK> i'm short circuiting it slightly
[2008/03/21 01:49:55] <hari> but basically..
[2008/03/21 01:50:06] <TSCHAK> it's so I can trigger the show mame on the orbiter screen
[2008/03/21 01:50:08] <hari> you react to the things happening on the orbiter screen
[2008/03/21 01:50:12] <bmac2> k
[2008/03/21 01:50:31] <TSCHAK> so that's how the PlugIn comes into the picture
[2008/03/21 01:50:37] <bmac2> so I want to do the online radio which was mediatype 6 in the first table
[2008/03/21 01:50:39] <TSCHAK> so now the media plugin KNOWS
[2008/03/21 01:50:46] <bmac2> so these are hte parts i need
[2008/03/21 01:50:59] <hari> knows?
[2008/03/21 01:51:06] <hari> 0.o
[2008/03/21 01:51:08] <TSCHAK> bmac2, you'll probably modify Xine_PlugIn/Player to support media type 6 as well
[2008/03/21 01:51:10] <bmac2> it knows knows
[2008/03/21 01:51:29] <bmac2> yes TSCHAK that is what I thought but it would be nice if radio was kinda seperate?
[2008/03/21 01:51:38] <bmac2> anyway
[2008/03/21 01:51:40] <bmac2> back to this
[2008/03/21 01:51:44] <bmac2> the plugin KNOWS
[2008/03/21 01:51:45] <TSCHAK> bmac2, then sure, another plugin and player pair
[2008/03/21 01:51:47] <bmac2> KNOWS what?
[2008/03/21 01:51:57] <shaggy71875_lmce> i want to stream a videotype to orbiters via mjpeg 10fps and depending on screen 320x240
[2008/03/21 01:52:01] <hari> knows?
[2008/03/21 01:52:04] <hari>
[2008/03/21 01:52:08] <TSCHAK> media plugin gets a pointer to this plugin
[2008/03/21 01:52:16] <bmac2> ok
[2008/03/21 01:52:20] <bmac2> so it knows WHAT to play
[2008/03/21 01:52:22] <TSCHAK> that basically says, "Hey, I'll handle this!"
[2008/03/21 01:52:25] <bmac2> or that when you chose a tyhpe
[2008/03/21 01:52:28] <bmac2> it claims it
[2008/03/21 01:52:43] <bmac2> or chose a file with the right extension it takes over
[2008/03/21 01:52:43] <TSCHAK> yes, now if you were to look at Xine Plugin's commands
[2008/03/21 01:52:46] <TSCHAK> you would see
[2008/03/21 01:52:54] <TSCHAK> commands for Create Media Stream
[2008/03/21 01:52:57] <TSCHAK> Start Media Stream
[2008/03/21 01:52:59] <TSCHAK> Stop Media Stream.
[2008/03/21 01:53:01] <TSCHAK> etc...
[2008/03/21 01:53:02] <hari> TSCHAK: does the mediaplugin also use FindPluginByTemplate?
[2008/03/21 01:53:04] <bmac2> yes
[2008/03/21 01:53:09] <bmac2> saw some of that
[2008/03/21 01:53:09] <TSCHAK> hari, yes.
[2008/03/21 01:53:21] <TSCHAK> let's look at CreateMediaStream
[2008/03/21 01:53:26] <shaggy71875_lmce> well for playing from an orbiter i might have to add more ugg bad as mame plugin
[2008/03/21 01:53:42] <bmac2> where is that TSCHAK ?
[2008/03/21 01:53:46] <bmac2> on the webmin?
[2008/03/21 01:53:50] <bmac2> or in the database?
[2008/03/21 01:53:51] <hari> TSCHAK:  so but we still have to register our media type with the plugin, don't we?
[2008/03/21 01:53:52] <bmac2> or a file?
[2008/03/21 01:54:02] <shaggy71875_lmce> think in Xine template
[2008/03/21 01:54:03] <TSCHAK> bmac2, in the same file
[2008/03/21 01:54:07] <bmac2> k
[2008/03/21 01:54:21] <TSCHAK> hari, no, remember, it's registered with the player
[2008/03/21 01:54:31] <TSCHAK> hari, and the plugin says, "I handle these players"
[2008/03/21 01:54:35] <hari> ah
[2008/03/21 01:54:54] <TSCHAK> it's a many to many media architecture
[2008/03/21 01:54:59] <bmac2> TSCHAK, what line?
[2008/03/21 01:55:06] <TSCHAK> as such the code path can go all over the place
[2008/03/21 01:55:27] <shaggy71875_lmce> and confuse the hell outa anyone looking at the code
[2008/03/21 01:55:27] <TSCHAK> bmac2, search for CreateMediaStream
[2008/03/21 01:56:05] <TSCHAK> class MediaStream *MAME_PlugIn::CreateMediaStream( class MediaHandlerInfo *pMediaHandlerInfo, int iPK_MediaProvider, vector<class EntertainArea *> &vectEntertainArea, MediaDevice *pMediaDevice, int iPK_Users, deque<MediaFile *> *dequeFilenames, int StreamID )
[2008/03/21 01:56:06] <TSCHAK> yup
[2008/03/21 01:56:10] <bmac2> line 259
[2008/03/21 01:56:30] <TSCHAK> now look at what we do
[2008/03/21 01:56:33] <bmac2> creates a class of media
[2008/03/21 01:56:39] <TSCHAK> we create our custom media stream
[2008/03/21 01:56:41] <bmac2> called pMAMEMediaStream
[2008/03/21 01:56:44] <TSCHAK> yup
[2008/03/21 01:56:51] <TSCHAK> that's in MAMEMediaStream.cpp
[2008/03/21 01:56:57] <bmac2> see I almost sound like I got a clue
[2008/03/21 01:56:59] <bmac2> lol
[2008/03/21 01:57:02] <TSCHAK> the base class is MediaStream.cpp in Media_Plugin/
[2008/03/21 01:57:15] <TSCHAK> go ahead and open MediaStream.cpp too
[2008/03/21 01:57:54] <TSCHAK> see?
[2008/03/21 01:58:04] <bmac2> andok got that open
[2008/03/21 01:58:35] <TSCHAK> so basically our media stream
[2008/03/21 01:58:37] <TSCHAK> gets its own type
[2008/03/21 01:58:45] <TSCHAK> and defines a few basic capabilities
[2008/03/21 01:58:59] <TSCHAK> including ContainsVideo
[2008/03/21 01:59:02] <TSCHAK> which sets true
[2008/03/21 01:59:30] <TSCHAK> but as you can see
[2008/03/21 01:59:33] <TSCHAK> i just subclass it
[2008/03/21 01:59:38] <TSCHAK> and return true anyway
[2008/03/21 01:59:46] <TSCHAK> see, ContainsAudio and ContainsVideo are special
[2008/03/21 01:59:49] <TSCHAK> because they determine whether
[2008/03/21 01:59:51] <TSCHAK> guess what?
[2008/03/21 01:59:54] <TSCHAK> you turn on the audio
[2008/03/21 01:59:55] <TSCHAK> or the video
[2008/03/21 01:59:56] <TSCHAK> pipe
[2008/03/21 01:59:57] <TSCHAK> :-)
[2008/03/21 02:00:01] <bmac2> or both?
[2008/03/21 02:00:04] <TSCHAK> or both
[2008/03/21 02:00:09] <TSCHAK> i should implement containsaudio too
[2008/03/21 02:00:11] <TSCHAK> but it's already true
[2008/03/21 02:00:12] <TSCHAK> ;-)
[2008/03/21 02:00:28] <bmac2> ok
[2008/03/21 02:00:33] <bmac2> so what else we have to do?
[2008/03/21 02:00:34] <hari> audio is always true?
[2008/03/21 02:00:38] <TSCHAK> making sense?
[2008/03/21 02:00:39] <bmac2> now that we been around the world
[2008/03/21 02:00:41] <TSCHAK> yeah
[2008/03/21 02:00:41] <bmac2> lol
[2008/03/21 02:00:42] <bmac2> yes
[2008/03/21 02:00:45] <bmac2> makes sense
[2008/03/21 02:00:52] <TSCHAK> oh we still have some more code to wade through
[2008/03/21 02:00:58] <bmac2> ok
[2008/03/21 02:01:04] <TSCHAK> i was opening mamemediastream because this contains capabilities the plugin needs to know
[2008/03/21 02:05:56] <TSCHAK> hari, so yeah, at this point, we basically need to implement CreateMediaStream
[2008/03/21 02:06:01] <TSCHAK> hari, which you can go ahead and look through
[2008/03/21 02:07:23] <TSCHAK> okay so
[2008/03/21 02:07:27] <TSCHAK> let's look at CreateMediaStream
[2008/03/21 02:07:39] <hari> thats cool: FindMediaDeviceForEntertainArea
[2008/03/21 02:07:47] <TSCHAK> is there anything I need to explain here?
[2008/03/21 02:07:57] <hari> gimme some seconds
[2008/03/21 02:08:01] <TSCHAK> basically the whole idea here
[2008/03/21 02:08:07] <TSCHAK> is to create the media stream of our media stream type
[2008/03/21 02:08:19] <TSCHAK> call find device for entertainment area to get all the devices that map to that
[2008/03/21 02:08:45] <TSCHAK> and return the media stream
[2008/03/21 02:08:51] <TSCHAK> which basically goes right back into StartMedia
[2008/03/21 02:09:02] <hari> yep
[2008/03/21 02:09:09] <TSCHAK> these are classes that are overridden from Media_Plugin
[2008/03/21 02:09:31] <bmac2> so the media_Plugin overrides all else?
[2008/03/21 02:09:34] <bmac2> or does it depend?
[2008/03/21 02:09:42] <bmac2> on what it is?
[2008/03/21 02:10:04] <TSCHAK> all of the classes in here derive from Media_Plugin
[2008/03/21 02:10:27] <bmac2> ok
[2008/03/21 02:10:30] <bmac2> next then
[2008/03/21 02:10:43] <hari> TSCHAK:         SendCommand(CMD_Play_Media);
[2008/03/21 02:10:57] <TSCHAK> yup
[2008/03/21 02:11:02] <TSCHAK> if you look immeidately above it
[2008/03/21 02:11:05] <TSCHAK> you see the formed command
[2008/03/21 02:11:08] <hari> aah
[2008/03/21 02:11:28] <TSCHAK> as you can see
[2008/03/21 02:11:29] <TSCHAK> it's just
[2008/03/21 02:11:30] <TSCHAK> another
[2008/03/21 02:11:32] <TSCHAK> DCE command
[2008/03/21 02:11:33] <TSCHAK> ;-)
[2008/03/21 02:11:44] <bmac2> ok don't see the CMD_Play stuff
[2008/03/21 02:11:47] <bmac2> what file is that in?
[2008/03/21 02:12:06] <hari> DCE == Device Commands Everywhere
[2008/03/21 02:12:37] <hari> bmac2: MAME_PlugIn.cpp
[2008/03/21 02:12:49] <bmac2> k
[2008/03/21 02:13:08] <hari> :362
[2008/03/21 02:13:20] <bmac2> got it
[2008/03/21 02:13:20] <TSCHAK> StopMedia does the opposite
[2008/03/21 02:13:23] <TSCHAK> kills the handles etc
[2008/03/21 02:13:27] <TSCHAK> but you can see in MAME_Player
[2008/03/21 02:13:35] <TSCHAK> that this is where I talk to MAME
[2008/03/21 02:13:54] <TSCHAK> using App Server, to launch MAME
[2008/03/21 02:14:04] <bmac2> let me explain this to see if i got it right
[2008/03/21 02:14:10] <TSCHAK> and my WindowUtils lib, to send keypresses to the mame window
[2008/03/21 02:14:11] <TSCHAK> bmac2, ok
[2008/03/21 02:14:14] <bmac2> you put these sections in ONLY for the commands you want
[2008/03/21 02:14:24] <bmac2> and below it makes sure that there is a proper device
[2008/03/21 02:14:27] <bmac2> before it sends the media
[2008/03/21 02:14:33] <bmac2> i.e.  if there is no screeen
[2008/03/21 02:14:37] <bmac2> it won't send video
[2008/03/21 02:14:42] <bmac2> etc
[2008/03/21 02:14:46] <TSCHAK> yes.
[2008/03/21 02:14:47] <bmac2> k
[2008/03/21 02:14:50] <bmac2> with you then
[2008/03/21 02:14:53] <TSCHAK> you have to program defensively
[2008/03/21 02:14:59] <bmac2> and you need ONE section for EVERY command
[2008/03/21 02:15:05] <TSCHAK> yes.
[2008/03/21 02:15:17] <bmac2> this almost makes sense to me
[2008/03/21 02:15:42] <TSCHAK> you need to make a DCE device
[2008/03/21 02:15:46] <TSCHAK> even if it's just a dummy device
[2008/03/21 02:15:49] <TSCHAK> that says HI I'M ON
[2008/03/21 02:15:49] <bmac2> k
[2008/03/21 02:15:51] <TSCHAK> HI I'm OFF
[2008/03/21 02:15:57] <TSCHAK> so you'll understand what's going on
[2008/03/21 02:16:12] <TSCHAK> you see
[2008/03/21 02:16:17] <TSCHAK> the Player device
[2008/03/21 02:16:19] <TSCHAK> is ALWAYS running
[2008/03/21 02:16:25] <TSCHAK> do you guys understand that?
[2008/03/21 02:16:28] <hari> yes
[2008/03/21 02:16:31] <bmac2> yes

[hari]

[2008/03/21 02:16:34] <TSCHAK> both the plugin and the player are always running
[2008/03/21 02:16:36] <bmac2> it has to be running
[2008/03/21 02:16:38] <hari> it registers with the dcerouter
[2008/03/21 02:16:40] <TSCHAK> because they have to accept commands
[2008/03/21 02:16:41] <bmac2> to check to see if it is needed
[2008/03/21 02:16:43] <TSCHAK> yes
[2008/03/21 02:16:53] <bmac2> and check commands against the database of what it "owns"
[2008/03/21 02:16:57] <TSCHAK> yes
[2008/03/21 02:17:25] <TSCHAK> now once you've implemented the plugin and player pair at a base level
[2008/03/21 02:17:36] <TSCHAK> assuming that you don't put anything inside the player
[2008/03/21 02:17:37] <TSCHAK> just stubs
[2008/03/21 02:17:38] <hari> bmac2: you may want to look at that later: http://forum.linuxmce.org/index.php?topic=3675.0
[2008/03/21 02:17:45] <TSCHAK> you'll see an orbiter playing menu
[2008/03/21 02:17:53] <TSCHAK> with your left hand menu
[2008/03/21 02:17:59] <TSCHAK> and the photo screensaver stopped
[2008/03/21 02:18:11] <TSCHAK> and if you look on the floorplan
[2008/03/21 02:18:12] <TSCHAK> guess what?
[2008/03/21 02:18:26] <hari> the media stream
[2008/03/21 02:18:28] <TSCHAK> the picture's filename will be displayed
[2008/03/21 02:18:43] <TSCHAK> also, if you click on multiple pictures
[2008/03/21 02:18:46] <TSCHAK> the playlist will build up
[2008/03/21 02:19:13] <TSCHAK> and since you're using the 4964 designobj which has the video commands in there
[2008/03/21 02:19:17] <TSCHAK> you can manage the playlist
[2008/03/21 02:19:18] <TSCHAK> save it
[2008/03/21 02:19:22] <TSCHAK> etc..etc..etc..
[2008/03/21 02:19:24] <bmac2> k
[2008/03/21 02:19:26] <hari> all for free
[2008/03/21 02:19:28] <bmac2> makes sense
[2008/03/21 02:19:30] <TSCHAK> and the commands will do the right thing.
[2008/03/21 02:19:40] * bmac2 wonders about hari's definition of FREE?
[2008/03/21 02:19:47] <TSCHAK> hehe
[2008/03/21 02:19:49] <TSCHAK> soo
[2008/03/21 02:19:52] <TSCHAK> with this
[2008/03/21 02:19:58] <bmac2> ok we got it all set up life is good
[2008/03/21 02:20:00] <TSCHAK> i hope, that the media subsystem makes more sense now
[2008/03/21 02:20:02] <bmac2> what is left?
[2008/03/21 02:20:15] <TSCHAK> basically, implementing the player commands
[2008/03/21 02:20:23] <TSCHAK> that's about it
[2008/03/21 02:20:26] <bmac2> ok
[2008/03/21 02:20:35] <TSCHAK> of course
[2008/03/21 02:20:37] <bmac2> and the commands we need for the pictures are
[2008/03/21 02:20:39] <TSCHAK> we will in the long run
[2008/03/21 02:20:40] <bmac2> forward one
[2008/03/21 02:20:42] <hari> and ripping the fading code out of the Photo_Screensaver
[2008/03/21 02:20:43] <bmac2> back one
[2008/03/21 02:20:47] <bmac2> pause
[2008/03/21 02:20:49] <bmac2> screenshow
[2008/03/21 02:20:57] <bmac2> time for each pic in screenshow
[2008/03/21 02:21:13] <TSCHAK> things like time, etc... are implemented as device data
[2008/03/21 02:21:17] <bmac2> k
[2008/03/21 02:21:21] <TSCHAK> for defaults
[2008/03/21 02:21:35] <TSCHAK> those can be gotten via the DEVICEDATA_ macros
[2008/03/21 02:21:38] <TSCHAK> but also
[2008/03/21 02:21:39] <bmac2> but don't you want it to be a choosable value?
[2008/03/21 02:21:45] <TSCHAK> i'm getting to that
[2008/03/21 02:21:48] <bmac2> lol
[2008/03/21 02:21:49] <TSCHAK> this sets a default baseline
[2008/03/21 02:21:50] <bmac2> sorry
[2008/03/21 02:21:52] <bmac2> running ahead
[2008/03/21 02:21:57] <bmac2> in my mind
[2008/03/21 02:22:01] <TSCHAK> this system makes me think about details
[2008/03/21 02:22:12] <TSCHAK> because if you don't fill in the details
[2008/03/21 02:22:13] <TSCHAK> guess what?
[2008/03/21 02:22:16] <TSCHAK> SHIT SEGFAULTS
[2008/03/21 02:22:17] <TSCHAK> ;-)
[2008/03/21 02:22:19] <bmac2> if fubars?
[2008/03/21 02:22:30] <bmac2> kicks your dog?
[2008/03/21 02:22:32] <TSCHAK> there is one other thing I wish to mention
[2008/03/21 02:22:33] <hari> and burns your kitchen sink?
[2008/03/21 02:22:38] <TSCHAK> there is a special Device Data parameter
[2008/03/21 02:22:44] <TSCHAK> if you look in the device data for Xine Player
[2008/03/21 02:22:45] <bmac2> how special is it?
[2008/03/21 02:22:50] <hari> implements dce?
[2008/03/21 02:22:54] <TSCHAK> you'll see a parameter called Name
[2008/03/21 02:23:03] <TSCHAK> this has to be implemented for ALL media players
[2008/03/21 02:23:09] <TSCHAK> HAS TO
[2008/03/21 02:23:20] <TSCHAK> it corresponds to a WM_CLASS tuple
[2008/03/21 02:23:20] <hari> #156 Name(string)
[2008/03/21 02:23:25] <TSCHAK> yes
[2008/03/21 02:23:28] <bmac2> ok the name string?
[2008/03/21 02:23:30] <bmac2> ok
[2008/03/21 02:23:36] <bmac2> what does that do?
[2008/03/21 02:23:37] <TSCHAK> this is needed so that Orbiter
[2008/03/21 02:23:38] <hari> ah, so that goes to front..
[2008/03/21 02:23:41] <TSCHAK> can manage the window that we display
[2008/03/21 02:23:41] <TSCHAK> :-)
[2008/03/21 02:23:44] <hari> by the window manager
[2008/03/21 02:23:47] <bmac2> ok
[2008/03/21 02:23:49] <TSCHAK> yes, by wmctrl
[2008/03/21 02:23:53] <bmac2> it has to know WHAT name is is calling
[2008/03/21 02:23:55] <TSCHAK> orbiter uses wmctrl to shift stuff around
[2008/03/21 02:23:58] <bmac2> k
[2008/03/21 02:24:08] <TSCHAK> this is so that it can overlay the orbiter menu correctly etc
[2008/03/21 02:24:21] <TSCHAK> and resize the window
[2008/03/21 02:24:22] <TSCHAK> see
[2008/03/21 02:24:36] <TSCHAK> the application desktop object (see HADesigner), may be different sizes
[2008/03/21 02:24:36] <bmac2> and since we are stealing the xine stuff it will work in the current screens already designed
[2008/03/21 02:24:42] <bmac2> so we don't have to design new ones
[2008/03/21 02:24:52] <TSCHAK> yes, to a point.
[2008/03/21 02:25:00] <TSCHAK> we're actually using photo_screensaver
[2008/03/21 02:25:04] <bmac2> k
[2008/03/21 02:25:12] <TSCHAK> the boilerplate comes from xine_player/plugin
[2008/03/21 02:25:18] <bmac2> but we avoid building brand new screens from scratch
[2008/03/21 02:25:21] <TSCHAK> yes
[2008/03/21 02:25:36] <bmac2> ok
[2008/03/21 02:25:39] <bmac2> what else?
[2008/03/21 02:25:44] <TSCHAK> thinking
[2008/03/21 02:25:45] <bmac2> to make our notes complete?
[2008/03/21 02:25:57] <TSCHAK> god i am rattling this all out of my brain
[2008/03/21 02:26:58] <TSCHAK> remember the speed_OSD screen? ;-)
[2008/03/21 02:27:00] <bmac2> yes
[2008/03/21 02:27:03] <TSCHAK> okay
[2008/03/21 02:27:06] <TSCHAK> it emits
[2008/03/21 02:27:10] <TSCHAK> Change Playback Speed command
[2008/03/21 02:27:19] <bmac2> yes that was in a table too I believe
[2008/03/21 02:27:22] <TSCHAK> which has a value of 1, 10, 100, 1000, 10000
[2008/03/21 02:27:22] <TSCHAK> etc.
[2008/03/21 02:27:26] <bmac2> yes
[2008/03/21 02:27:29] <TSCHAK> you use that
[2008/03/21 02:27:31] <bmac2> in what?  milliseconds?
[2008/03/21 02:27:35] <TSCHAK> doesn't matter
[2008/03/21 02:27:37] <TSCHAK> arbitrary value
[2008/03/21 02:27:40] <bmac2> k
[2008/03/21 02:27:46] <TSCHAK> we change it to whatever we want
[2008/03/21 02:27:54] <bmac2> and that does what to the stream?
[2008/03/21 02:28:04] <TSCHAK> it doesn't do anything to the stream
[2008/03/21 02:28:18] <TSCHAK> media plugin just sends a command to the player
[2008/03/21 02:28:21] <TSCHAK> to say "Change Playback Speed"
[2008/03/21 02:28:22] <bmac2> oh ok
[2008/03/21 02:28:31] <TSCHAK> even Pause and Play, are Change Playback Speed commands once the thing is running.
[2008/03/21 02:28:43] <bmac2> makes sense treats them all the same
[2008/03/21 02:28:53] <TSCHAK> so now
[2008/03/21 02:28:54] <bmac2> instead of seperate command structures
[2008/03/21 02:28:55] <shaggy71875_lmce> and rewind is also?
[2008/03/21 02:28:56] <bmac2> so it is cleaner
[2008/03/21 02:28:56] <TSCHAK> we have our speed control.
[2008/03/21 02:28:59] <bmac2> k
[2008/03/21 02:29:03] <TSCHAK> shaggy71875_lmce, yes, change playback speed.
[2008/03/21 02:29:08] <shaggy71875_lmce> or is it a - intiger
[2008/03/21 02:29:15] <TSCHAK> negative integer
[2008/03/21 02:29:23] <TSCHAK> it's a signed in
[2008/03/21 02:29:24] <TSCHAK> int
[2008/03/21 02:29:24] <bmac2> but still a change playback speed
[2008/03/21 02:29:27] <TSCHAK> yes
[2008/03/21 02:29:35] <TSCHAK> so now you have
[2008/03/21 02:29:37] <shaggy71875_lmce> hmm
[2008/03/21 02:29:39] <TSCHAK>  change playback speed with the remote
[2008/03/21 02:29:44] <TSCHAK> no matter which remote you use
[2008/03/21 02:29:53] <shaggy71875_lmce> or gyro?
[2008/03/21 02:29:53] <TSCHAK> ;-)
[2008/03/21 02:29:55] <TSCHAK> yes
[2008/03/21 02:30:08] <TSCHAK> now, we also have
[2008/03/21 02:30:08] <bmac2> lol
[2008/03/21 02:30:13] <TSCHAK> one last detail
[2008/03/21 02:30:15] <TSCHAK> we can set position
[2008/03/21 02:30:16] <bmac2> k
[2008/03/21 02:30:16] <TSCHAK> in this case
[2008/03/21 02:30:21] <TSCHAK>  it will be the picture in the stream
[2008/03/21 02:30:23] <TSCHAK> we can use that
[2008/03/21 02:30:28] <TSCHAK> to populate the transport bar
[2008/03/21 02:30:29] <TSCHAK> :-)
[2008/03/21 02:30:43] <TSCHAK> and from that, we have full transport control
[2008/03/21 02:30:46] <TSCHAK> and um
[2008/03/21 02:30:54] <TSCHAK> oh yeah, well, that's the other thing
[2008/03/21 02:30:57] <bmac2> lol
[2008/03/21 02:30:58] <TSCHAK> we'll probably use SectionedMedia
[2008/03/21 02:31:02] <TSCHAK> because we'll treat it
[2008/03/21 02:31:06] <TSCHAK> as a DVD with chapters, more or less.
[2008/03/21 02:31:16] <bmac2> as each picture as a seperate section
[2008/03/21 02:31:17] <TSCHAK> which means, that playlisst commands just cause a jump to playlist command
[2008/03/21 02:31:26] <TSCHAK> which can be dealt with
[2008/03/21 02:31:39] <TSCHAK> there's all sorts of stuff
[2008/03/21 02:31:40] <bmac2> ok
[2008/03/21 02:31:42] <TSCHAK> look in Media Plugins
[2008/03/21 02:31:44] <TSCHAK> Plugin
[2008/03/21 02:31:44] <bmac2> be bakc in a while
[2008/03/21 02:31:45] <TSCHAK> Study it
[2008/03/21 02:31:46] <TSCHAK> know it
[2008/03/21 02:31:48] <bmac2> thanks TSCHAK
[2008/03/21 02:31:50] <TSCHAK> you have to know it
[2008/03/21 02:31:51] <bmac2> that was good
[2008/03/21 02:31:56] <TSCHAK> bmac2, you're welcome.
[2008/03/21 02:31:57] <shaggy71875_lmce> will each "chapter" we use be another song in the playlist or chapters be a time frame within one song
[2008/03/21 02:32:03] <hari> yeah, THANK YOU VERY MUCH!!!
[2008/03/21 02:32:14] <hari> that made many things clear..
[2008/03/21 02:32:19] <TSCHAK> shaggy71875_lmce, that will have to be decided after we get the mechanics working for just pictures.
[2008/03/21 02:32:27] <TSCHAK> god i hope it made sense
[2008/03/21 02:32:33] <shaggy71875_lmce> ok
[2008/03/21 02:32:38] <TSCHAK> there is a LOT to take in
[2008/03/21 02:32:39] <TSCHAK> I know
[2008/03/21 02:32:42] <TSCHAK> and I am SURE
[2008/03/21 02:32:44] <TSCHAK> i left some shit out

[totallymaxed]

Nice way to document the conversation you guys had about this... ;-)

[andymck]

Makes interesting reading, def a lot to take in...following with interest

[andymck]

If any of you can can see any way in which i might be able assist in any way with this i would be happy to do what i can.  I am a developer with reasonably good c++ skills but dont have any real knowledge of this environment and so not sure how much i could contribute in the short term but if you need any testing etc please let me know.  I plan to setup a development environment over the weekend and start looking at the inards in any case....
