Public bug reported:
Having problems watching TV with totem/gnome-dvb-daemon: no sound on
Danish MPEG4 channels. MPEG2 channels are OK.
I isolated the problem to gstreamer that stops when decoding the audio stream:
GST_DEBUG=mpeg*:5 gst-launch-0.10 dvbbasebin inversion=AUTO bandwidth=8
frequency=714000000 program-numbers=2030 ! decodebin name=decoder decoder. !
queue ! alsasink decoder. ! xvimagesink > debug_audio.txt 2>&1
Playing without audio works without problems:
GST_DEBUG=mpeg*:5 gst-launch-0.10 dvbbasebin inversion=AUTO bandwidth=8
frequency=714000000 program-numbers=2030 ! decodebin name=decoder decoder. !
queue ! xvimagesink > debug_no_audio.txt 2>&1
Running the above commands work with and without audio on MPEG2
channels.
The output of the commands are attached. My debugging skills ends here.
