Debug output

I'm using playbin2 to play an MPEG transport stream and while the video plays
fine there is no audio.  The same audio and video tracks play fine when I use a
program stream instead.

Could you make a sample available somewhere?

Possibly even the first megabyte would be sufficient (and could be attached) and can be obtained with 'head --bytes=1000k foo.mpg > head.mpg'.
Comment 2 Alan Mock 2009-08-26 16:10:18 UTC
This is coming from a multicast stream so I don't have an file to upload.  I used VLC to save the stream to a file but I was not able to play the saved files at all using GStreamer.  If you would like me to record the stream differently let me know and I can make those files available.

http://machintosh.net/mpegtssamples/sample.ts  -- This is recorded with the MPEG TS encapsulation method

http://machintosh.net/mpegtssamples/sample-1000k.mpg  -- This is recorded with the MPEG TS encapsulation method and Dump raw input selected

http://machintosh.net/mpegtssamples/rawstream.mpg  -- This is the same as above except longer.

    mpegtsdemux: Stream type 0x81 is normal AC3, not EAC3
    
    Not sure what the stream type for EAC3 is though.
    
    Fixes bug #593059.
