It seems AFD fails to find correct audio format or audio channels altogether which results in no audio at all. The audio is fine if I play the same recording with ffplay. Sometimes audio is recognized as MP3 (while it is MPEG2). If I fast-forward couple of minutes, set a bookmark, and start play again, audio tracks are occasionally recognized correctly. I can submit a .ts sample if needed. When it's working its like this in log: {{{ 2017-03-06 19:25:17.844709 I AFD: codec MP2 has 2 channels 2017-03-06 19:25:17.844809 I AFD: Opened codec 0x5390420, id(MP2) type(Audio) 2017-03-06 19:25:17.844880 I AFD: Opened codec 0x5156c80, id(DVB_SUBTITLE) type(Subtitle) 2017-03-06 19:25:17.844905 I AFD: Opened codec 0x7685120, id(DVB_SUBTITLE) type(Subtitle) 2017-03-06 19:25:17.846609 I AFD: Opened codec 0x7677ec0, id(MPEG2VIDEO) type(Video) 2017-03-06 19:25:17.846652 I AOBase: Opening audio device 'pulse' ch 2(2) sr 48000 sf signed 16 bit reenc 0 }}} When its not, its like this: {{{ 2017-03-06 19:26:40.752511 I TV::StartPlayer(): Created player. 2017-03-06 19:26:40.752558 I TV::HandleStateChange(): Changing from None to WatchingPreRecorded 2017-03-06 19:26:40.753357 I TV::HandleStateChange(): Main UI disabled. 2017-03-06 19:26:40.753429 I TV::StartTV(): Entering main playback loop. 2017-03-06 19:26:40.754377 E AFD: Unknown video codec - defaulting to MPEG2 2017-03-06 19:26:40.758903 N VidOutGL: Deferring creation of OpenGL resources 2017-03-06 19:26:40.759534 I AFD: Opened codec 0x7f0f90005fc0, id(MPEG2VIDEO) type(Video) 2017-03-06 19:26:40.759550 N AudioPlayer: Enabling Audio 2017-03-06 19:26:40.808931 N VidOutGL: Deferring creation of OpenGL resources 2017-03-06 19:26:40.841603 I GLVid: Using custom UYVY input textures. 2017-03-06 19:26:43.820909 E AFD: Unknown video codec - defaulting to MPEG2 2017-03-06 19:26:43.824808 N VidOutGL: Deferring creation of OpenGL resources 2017-03-06 19:26:43.825732 I AFD: Opened codec 0x7f0f900184c0, id(MPEG2VIDEO) type(Video) 2017-03-06 19:26:43.869561 E AFD: Unknown decoding error 2017-03-06 19:26:43.869600 E AFD: Unknown decoding error 2017-03-06 19:26:43.869690 E AFD: Unknown decoding error 2017-03-06 19:26:43.869756 E AFD: Unknown decoding error 2017-03-06 19:26:43.869815 E AFD: Unknown decoding error 2017-03-06 19:26:43.869870 E AFD: Unknown decoding error 2017-03-06 19:26:43.869935 E AFD: Unknown decoding error 2017-03-06 19:26:43.870047 E AFD: Unknown decoding error 2017-03-06 19:26:43.894591 N VidOutGL: Deferring creation of OpenGL resources 2017-03-06 19:26:43.927323 I GLVid: Using custom UYVY input textures. }}} (those are from same recording, first sample playback started 5 minutes from start) All the other channels play the audio just fine.
