Users / Re: AAC multi-channel to AC3 on-the-fly re-encode with Xine?
« on: December 10, 2009, 08:09:31 pm »
OK, that explains why there is no audio when playing theese 5.1 clips :

Yepper.  Although I do get audio when I play them, I only get the L&R channels in LPCM format through the S/PDIF cable.

I use the Fantastic 4 720P trailer and one of the I am Legend 1080P trailers, from that site, for my testing.  The FF trailer plays with audio just fine because it is stereo.  The I am Legend trailer only passes the L&R audio.  Anything encoded with multi-channel (>2ch) AAC will act this way (wrt audio).

Not sure if this is of any help, Onkyo seems to support AAC.

Many, many receivers support AAC... through Ethernet UPNP and USB.  I've not found any device that supports AAC over S/PDIF, I don't believe it is possible.


I did some playing and a little php/html learning and have altered the script to the point where it outputs a file I can save.  This part was pretty easy.  I don't know if the output is correct as I am not very familiar with the database.  I am unable to import the resulting file back into the database as I am getting sql errors on insert statements.  I am looking into this and will post any progress I make.

Progress report, what I know so far:

After much searching I havn't found a single Receiver which supports 6ch AAC over S/PDIF (exceeds the spec bitrate it seems).  And the current method xine uses to handle AAC via S/PDIF causes it to output in PCM mode only sending the L/R channels, no centre, no rears, no sub.  An HDMI audio connection should not be affected by this as it can handle 6ch of PCM.

There are three ways to deal with this:
1) Use analog 6ch outputs from the MD to the receiver and configure ALSA accordingly (best sound quality, I don`t think AVWizard supports this currently but I havn't checked)
2) Have xine re-encode the AAC to AC3 (or DTS preferably) for S/PDIF output 'on-the-fly'.
3) Have xine down-mix to 2 channel stereo for PCM or analog output and de-coding by a Dolby Pro Logic dsp.  (I REALLY don't want this)

I don't have enough cables, currently, to test #1, and I'd rather not do it this way (even though this gives a much higher sound quality due to lack of compression).  My cats love to chew wires and the fewer I have the better.

I would prefer #2 above but I have not figured out how to implement this functionality in xine_player (or even if xine has this functionality).  This is easy to implement with MPlayer (but would require playing all .mp4 files with mplayer... not desirable.)

So...  I am slowly reading up on xine and trying to push my way through (learning) some c++ coding in the spare time I do have.  For now I am resorting to playing .mp4 files with 6ch AAC using mplayer from the command line.  But I am hoping to figure a way to have xine convert 'on-the-fly' when an S/PDIF output has been selected in avwizard.


Thanks Thom, the plasmoid was the only way I knew how to return to orbiter short of a 'quick reload' from the webadmin


On to LinuxMCE related stuff:
- After entering KDE - How can one properly get back to LinuxMCE Orbiter?

There is a package called lmce-activate-orbiter-plasmoid which you could install to add this functionality, it is not installed by default.

Code: [Select]
apt-get install lmce-activate-orbiter-plasmoid

Then right-click on your kde desktop background and choose 'Add Widgets...' and choose 'Activate Orbiter' and it will add the plasmoid to your desktop.  Clicking the plasmoid should return you to the orbiter.  Works for me with UI2 on my core.  YMMV.


MAIN QUESTION: How do fellow LinuxMCE users configure MythTV for first time use? (mythtv-setup)

- I've recently learned about /usr/pluto/bin/
How is a user supposed to run mythtv-setup if mythtv-backend can't be stopped without Restart_MythBackend doing its thing?
- In my case, in Belgium, using dvb-t and a Hauppauge HVR-4000 we have to use a workaround to get program information into mythconverg (mc2xml)
- With the new myth 0.22 version, multiple frontends are supported (THANK YOU!!)
However, after killing restart_mythbackend, after stopping myth-backend and entering mythtv-setup, I am
100% able to choose the correct /dev/dvb/adapterN/frontendN. Problem is the adapter is not recognized, so scanning channels is impossible.
- When leaving myth-setup there is a warning like:
Code: [Select]
"Path /home/user_1/data/pvr does not exist" solve?This path off course does exist, but the initial user has no permission...

There is a common misconception, especially for people who are familiar with mythtv, about how to run mythtv-setup in LinuxMCE.  I got stock on this for a long time.

In LinuxMCE mythtv-setup should always be run from the 'Computing' menu in orbiter.

If you do this it will run with the proper permissions and some LinuxMCE script additions will deal with things like Restart_MythBackend automatically for you.  Your file permissions issue with /home/user_1/data/pvr should also be taken care of by running mythtv-setup from the computing menu as it will be running with proper permissions.


I know this is digging up an old topic but I've been trying to use this feature to backup my TV and Receiver device templates in 0810b2 and I'm getting some errors and no apparent output file.

The output I'm getting is here:

I'm thinking of doing a fresh install and would love to backup these templates first.  Is this working for anyone else right now?


Works great!  I was able to play the same divx movie (on CD in the core) on 3 MDs simultaneously with no issues.  I don't have optical drives in any of my MDs yet. Great work!

What format are the files you are playing in?  After reading your post I checked my ION 330.  My ripped .dvd files play fine with vdpau and my .mp4 files play (no proper handling of 5.1 AAC).  Some of my .mkv files play just fine and some have no video or audio, just a black screen.  I believe that xine has known issues with some .mkv format files.

Try looking at /var/log/pluto/XX_Xine_Player.log, on the MD, and see if anything shows there (where XX is the device # that Xine_player starts with on the MD).  I don't know if it will contain anything useful or not.

pedplar:  all lmce logs are located in /var/log/pluto/*  You may want to start with LaunchManager.log, you should be able to find which device is not starting.  It would also be a good idea to start another topic for the UI1 video blackout issue.  I will try to test this out this weekend sometime and see if I have the same issue.

_if_: Which issue?  UI2 not loading or UI1 video blackout during playback?

Hmm, I'm still playing with UI2 right now.  I remember something like you describe happening to me on the eeebox before but the machine is almost exclusively used for audio playback so I can't comment right now.  Sounds kinda like the screen saver/power off settings kicking in, try changing the power off time for the orbiter in webadmin, see if that makes a difference...

I had this problem exactly and it was because the avenard 'release' repo was not in /etc/apt/sources.list it was in /etc/apt/sources.list.d/avenard.list (I had put it there manually during alpha days and upgraded to beta2)...  This causes the to fail.  Put the avenard repo /etc/apt/sources.list as posde says and it worked like a charm!

Just to continue my story... I'm trying to troubleshoot a bit of why UI2 is causing X to crash on my EeeBox B202 (intel graphics).  The latest is in this thread:
