general stream error related to mod files' audio
Last modified: 2010-12-12 18:06:20 UTC
Initially filed on https://bugs.launchpad.net/ubuntu/+source/pitivi/+bug/508464 pulsesink.c(290): gst_pulsering_is_dead (): /GstPipeline:pipeline1/GstBin:pitivi-audiosink/GstAutoAudioSink:autoaudiosink2/GstPulseSink:autoaudiosink2-actual-sink-pulse This happens in PiTiVi git by seeking the following samples: http://launchpadlibrarian.net/38372383/MOV00D.MOD http://launchpadlibrarian.net/38372432/MOV00E.MOD
I can't really seem to reliably reproduce this with the two previous .MOD files, but I'm now able see this problem with some .vob files. With the vob file, this does seem to be related to pulseaudio, because you can see the "pitivi" application flashing frantically in gnome-volume-control's "applications" tab. It seems as if the stream was constantly opened and closed! Sample file: http://jeff.ecchi.ca/public/pitivi-608064-vts_02_1.vob
Symptoms: http://jeff.ecchi.ca/public/pitivi-608064-short.ogv
Created attachment 153830 [details] debug log with my vob file result of PITIVI_DEBUG=*:5 GST_DEBUG=2 bin/pitivi > debug.log 2>&1;
Created attachment 153831 [details] debug log with that guy's .MOD files PITIVI_DEBUG=*:5 GST_DEBUG=2 bin/pitivi > debug.log 2>&1; this debug log is much smaller than the first one.
Created attachment 153832 [details] debug log with that guy's .MOD files with GST_DEBUG=2,pulse*:5,*sink:5 PITIVI_DEBUG=5 instead.
Created attachment 153833 [details] debug log with my vob file with GST_DEBUG=2,pulse*:5,*sink:5 PITIVI_DEBUG=5 instead.
Needs investigation (because it breaks sound in those scenarios), so setting it target 0.13.4 so that we at least try to figure it out.
Bumping to next milestone :(
Downstream couldn't reproduce the problem anymore.
