Re: [vdr] vdr xine-lib eac3

Hi

I play with your sample , it has only one audio track and strictly no sound on it ...

So I decide to replace my recent xine-ui by the very latest here http://hg.debian.org/hg/xine-lib/xine-ui/

xine-lib is latest one with only your patch in mpeg-pes ffmpeg is the full latest git with absolutely no patch

the result is the same ..

So I destroy the /.xine/config file and I can open the ts file and play with audio track .. if I play too hard, I have the message saying :

-load_plugins: plugin vdpau_h264 will be used for video streamtype 4d. -Broken NAL, skip it. -ffmpeg_audio_dec: augmentation du buffer à 98304 pour éviter sa saturation. -load_plugins: plugin ffmpegaudio will be used for audio streamtype 41. -ffmpeg_audio_dec: trying to open null codec -audio_decoder: no plugin available to handle 'E-AC-3'

no more sound available ... so it's better

Back to vdr, I try to play with sound track and crash immediatly I remark that when crashing, and running xine-ui to reconnect to vdr playing my records, it has stop replay and fall back to live TV .. strange !!!

I was focusing on xine but on vdr log there is a message I didn't saw :

-SetPlayMode: 0 -SetPlayMode: 1 -SetPlayMode: 0 -SetPlayMode: 1 -SetDigitalAudioDevice: 1 -::write(2048) returned -1, error 32: Broken pipe -vdr-xine: Client disconnected! -SetPlayMode: 0 -SetPlayMode: 1 -SetDigitalAudioDevice: 0

I will report on our forum this event and ask my colleague to check also this part if they have time. In a short way does it means that vdr-xine ask xine-ui to break itself and stop replaying ?

For myself, I will break for one week hoping somebody will continue to test or find what can be wrong in our basis config

Thanks for your help and sorry to not have enough skills to debug or understand the source code

Best regards

I use latsest xine-ui hg. The problem may be ffmpeg or xine-lib or xine-ui. Are you sure that you have the latest versions and no aditional patches? You can do hg diff o svn diff to see the changes you have in the repositories. Here is a sample: http://dl.free.fr/pByrnmYwZ

Hi

I continue to search why it fail ... with no luck, hope other people will have time to make test

basis test setup : vdr 1.7.15 extention patch + patch e-ac3 for vdr-xine xine-ui 0.99.6 latest git ffmpeg latest xine 1.2 with basic e-ac3 patch for only

From vdr : crash every time I change audio track as described previously

Second test Try opening the TS file from xine-ui directly, same behaviour

op mode :

At startup sound track is "0" (should be "fra"), play nice track -- display track "off" , no crash track ++ display "0" instead of "fra" , no crash track ++ display "qaa" , it's real name .. crash in couple of seconds

Here is the log with high verbosity http://pastebin.com/BvGKDk0v

Hope this help you, I underline in yellow some strange thing

By the way, if you have time, can you post a sample of recording made at home so we can also test your sample with our configuration

Many thanks for your help and have a nice week end

Best regards

Here is the result of my colleague using vdr-sxfe verbose and changing the audio track

I will add this patch to my xine-lib and rebuild all

Here are two more samples to test given by colleague, I will also wait the answer from Karim Afifi to have comparative tests

http://dl.free.fr/mE6yTLPnx http://dl.free.fr/u2dWSU5R8

Other idea : may it comes from my xine-ui version ? did you use a fresh one from http://hg.debian.org/hg/xine-lib/xine-ui/

Many thanks for your help and have a nice evening

The error you report doesn't matter. It is because there is no case for EAC3. I have an additional patch to use only two channels, and I don't have this error. You can use the patch and comment the line: this->context->request_channels = 2; and then you don't have the error. I try with the sample you give to me. If you want you can give me another sample.

Hi

In fact, I use a very recent ffmpeg (less than one month) and the very latest xine-lib 1.2 with no patch except yours

I found my error message in combined/ffmpeg/ff_audio_decoder.c

This is strange that you cannot reproduce as long we (my colleague + me) are able to have it every time and other user report this problem using xlo plugin + sxfe (on French DVB forum)

I can update my ffmpeg to the very latest release but not sure it will change something (ffplay or mplayer works fine)

Nobody else can test our sample please ?

Have a nive evening
