For the first file, 1.flac ( http://ff123.net/samples/1.flac ) :

In this case, the audio plays correctly and the application exits normally at the end of the clip. Now the same thing but with an Ogg Vorbis sample ( http://www.archive.org/download/alexqmoon93/26.ogg ): $ gst-launch-0.10 filesrc location="26.ogg" ! decodebin ! fakesink Setting pipeline to PAUSED ...

Pipeline is PREROLLING ... Caught interrupt -- Pausing pipeline. Pipeline paused. WARNING: Element "pipeline0" warns: pipeline interrupted (This time, no audio is output and the application needs to be killed) I've just tried these files again in gstreamer and rhythmbox and neither will play the file still, giving the "Internal data flow error" error. Both files play in XMMS. -- totem & rhythmbox will not play Ogg Vorbis, Ogg Theora or Ogg FLAC on fresh Dapper install https://launchpad.net/bugs/40023 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
