Bug Description

Impact:
the audio playing with stop sometimes on ogg to flac transitions

Test Case:

Test in rhythmbox or try the upstream bug case:

"- play ogg vorbis file
 - seek near to the end
 - wait for about-to-finish
 - set new uri property (flac file)
 - playbin2 hangs when the transition should happen
 - a position query returns always the same value
 - state is still playing

Testcase: http://pastie.org/pastes/4283968/text (edit the uris..)"

Regression potential:
limited, check that playback and transitions from files to files works as it should

----

See upstream bug https://bugzilla.gnome.org/show_bug.cgi?id=680252

This is probably related to, but was NOT fixed along with, https://bugs.launchpad.net/ubuntu/+source/gst-plugins-base0.10/+bug/921071

Steps to reproduce:

* Deactivate crossfade in Rhythmbox
* Make a playlist from two files, first one an ogg, second one a flac
* Start playing this playlist, skip towards the end of the first (ogg) piece if you like
* Playback stops after reaching the end of the ogg file, Rhythmbox displays the title of the second file but the timer does not move over the 0:00 mark

I've attached the output of

GST_DEBUG=:5 rhythmbox --debug &> debug.log

while performing the above steps.

I'm experiencing the same bug here.
Now, seeing that a similar playback-pausing issue on mp3 to ogg transitions (lp: #921071) was fixed with a patched version of gst-plugins-base0.10 (0.10.36-1ubuntu0.1): "don't discard timestamps when consecutive input buffers have the same ts", could it perhaps be, that a similar patch needs to be applied to the handling of flac files in gst-plugins-base0.10 ?
Does anything stand out in the debug log?
Just guessing here.

I've uploaded to raring (not very useful since most of the defaults app transitioned to gst1) and a SRU to quantal, we can look at doing a precise SRU once the fix is confirmed to work on quantal

Good news!

I've tested the bug with rhythmbox, before, and after updating with the new gstreamer package, and it solved the ogg -> flac transition for me.

Many thanks!

I still use Ubuntu Precise, and this bug makes my crazy (i used to play randomly a lot of FLAC and OGG).

Is there any chance to have this fix available for Ubuntu Precise ?

Is there any way to get this fixed in 12.04? After all, it's an LTS.
