Users / SIP Cisco 7970?
« on: November 15, 2007, 06:50:44 am »
The Cisco 7970 support in LMCE (via the Asterisk subsystem) seems to use the 7970 in its default SCCP protocol version. But the 7970 can be upgraded to SIP protocol by upgrading its firmware (available for purchase from Cisco). And Asterisk's support for SIP is much more reliable and robust than its SCCP support. Does anyone have instructions for configuring the LMCE server as the TFTP server to perform the upgrade, and configuring the Asterisk subsystem to use it?

Developers / Fixing Rip Quality/Format Settings Usage Bugs
« on: November 15, 2007, 06:34:22 am »
I want to fix bugs Bug 3495 "DVD Changer rips CD's only with OGG" which might be related to Bug 3637 "Disk ripping does not use Quality setting information set via admin page". Both bugs are failure of the ripping script in to use the settings stored for format and quality. Zaerc has reported fixing 3637. I'd also like to add a "Rip All" button to the Admin website interface.

Where are the settings stored, and which executables call the script, in both the rip all and rip (single disc) use cases?

Setting the rip format in the Admin website doesn't make the ripping actually use the format specified, even after core reloads and server reboots. Bug 3495

Users / Rip Settings Not Working
« on: November 15, 2007, 06:19:19 am »
Turns out that setting the rip format in the Admin website Home -> Wizard -> Installation page Miscellaneous section "Ripping format for cd's" does not actually change the ripping format. The setting saves as a config value properly, but ripping continues to produce Ogg format files. I reloaded the core, and rebooted the LMCE server, but no change. Bug 3495

Do you know which files generate the Orbiter GUI that shows a CD that's available for playing, and the Admin website script (if it's not just handled by index.php) that shows the media browser?

In the Admin website, even the Media Browser view is really hard to read. The Properties page for albums and titles are even harder to read and sort out. And as you warned, the Delete link for those media objects failed with
Permission denied in /var/www/pluto-admin/operations/mediaBrowser/mainMediaBrowser.php on line 106

I'd like to fix that, but I have to find which file to fix. And hook up albums' delete links to delete and resync. Unless I find they're already fixed in the latest builds.

I got it (rip format settings) - and updated the "ripping" wiki entry. Thanks for the multiple replies in different threads to the same question :).

Now, how do I delete the test rips from the media collection? Other than use the commandline to tell Linux to delete the directories and then running a filesystem/catalog sync (from commandline script or GUI)? Is there a GUI feature to delete content? If not, how can I add one (which executable file and GUI "button" image)?

Users / Re: Changing CORE IP#?

Then why didn't you just ask that instead? 

Anyway I'm so glad you have solved this for once and for all so that we never have to answer these questions ever again...  ::)

And on a side note, don't you think it's just a little odd to give a virtual network adapter the exact same ip address as the physical adapter?

It's easy when you know how.

Search the wiki for DHCP for your DHCP problems.

Thanks. I have updated the Wiki entry on ripping.

There's lots of ripping params that are hardcoded in /usr/pluto/bin/ that aren't available in the GUI. How can I edit the GUI to allow setting, say, all the commandline FLAC codec parameters as a single string, as well as structured fields like compression level?

Also, I really like that the ripping entry has both a "user's guide" and a "programmer's guide", rudimentary as it might be. If every function in the architecture had documentation of its layers - GUI, network/API, script, data - this project would be a lot more accessible to new people both adopting it and improving it.

I guess I could continue to update the Wiki that way as I learn my way around, but encouraging others to do so as they improve both the docs and the code would make us more productive :).

Users / Specifying CD Rip Format?
« on: November 14, 2007, 05:29:34 am »
I have ripped CDs from my VGP-XL1B CD/DVD jukebox. But the rips always produce OGG files. Where can I select the output format, like WAV?

I searched the forums and the wiki, but couldn't find where to set the format. I did see the posts discussing the bug that doesn't apply quality settings to the rips. And I see in the ripping script that it can take a paramater specifying the format. But I haven't seen where to set the format.

After rebooting the LMCE host while fixing some other items (DHCP), the system is now ripping. But I can't find where to specify the rip should produce a WAV, or anything other than the OGG files it's producing.

Well if that is what you wanted, I guess you could just have turned off DHCP on the modem/router and configured the "external interface" (eth0 not the virtual eth0:0)  staticly in the modem/router's range.  Saves you the of trouble reconfiguring LMCE's DHCP server.
Yes, that is in fact what I wanted, except I also wanted the LMCE DHCP server to assign addresses in the existing LAN's Class C IP# range, and service LMCE devices that need LMCE's DHCP support. And I wanted to avoid (or recover from) the bug that regenerates the dhcpd.conf incorrectly. I also wanted to know what I was losing, the actual absolutely required losses, by using a single NIC. Know I know, and so does anyone else reading this thread (or the wiki, or the dhcpd.conf bug report).

What I wanted was for someone to explain how to do that, preferably point to an existing (and tested) explanation, since it's clearly a not uncommon setup. Now the next person will have a better chance of doing it in a few minutes, rather than a few hours, with a minimum of unnecessary noise as they search for the solution.

Feature requests & roadmap / Is There a Roadmap?
« on: November 13, 2007, 11:30:01 pm »
This forum is full of interesting feature requests. And it looks like "the end of November" is the target date for a new release. Which will reportedly upgrade Kubuntu to 7.10, MythTV to the latest version as of at earliest 10/07, and presumably all the patches made by sometime in November. Those changes alone will probably be quite a lot of good ones.

But is there an actual roadmap somewhere? Where new features are prioritized into expected upcoming milestones, with expected dates (or ranges, or offsets) assigned to them?

The remaining question is whether the PXE boot will work correctly. It may have some IP address issues hidden in some script that will appear out of nowhere (like so much else in this project). Will you be using a media director in your setup?

It looks like PXE boot is designed to rely on DHCP rather than hardcode:
Quote from: /etc/dhcp3/dhcpd.conf
allow booting;
allow bootp;

option space pxelinux;
option pxelinux.magic code 208 = string;
option pxelinux.configfile code 209 = text;
option pxelinux.pathprefix code 210 = text;
option pxelinux.reboottime code 211 = unsigned integer 32;


# PXE booting machines
group {
        filename "/tftpboot/pxelinux.0";
        option pxelinux.reboottime = 30;

If there are any PXE boot dependencies not properly dependent on DHCP, then the switch I did should be a good test to expose them. However, I do not have any media director hosts on my network yet (I'm trying out LMCE piece by piece, and it's been a good strategy so far :)).

Developers / Port DB layer to Postgres?
« on: November 13, 2007, 11:13:11 pm »
LMCE runs MySQL as its database server. I have an existing Postgres installation, and I'd rather not DBA two different databases. The PHP scripts seem to use ADO to connect to the DB, which might mean only the datasource has to be changed, but that's usually just wishful thinking. And there's lots more glue than in the PHP.

I see that there is a documented technique for distributing the MySQL server across the network, rather than running on the core localhost. But it seems untested, and just a hint at using a different RDBMS entirely.

Has anyone investigated or documented what it would take to port LMCE from MySQL to Postgres? Any notes on any dependencies of LMCE on MySQL specifically, either SQL syntax, or features, or some other constraint? OTOH, is anyone running LMCE on Postgres already?
