Description Todd 2010-12-29 06:32:30 UTC

Version:           4.4.3 (KDE 4.6.x) (using KDE 4.5.90) 
OS:                Linux

The phonon vlc backend does not handle matroska (mkv) video files properly.  It appears to treat them as audio files, playing the sound but no video.  The xine backend handles the same files just fine, as does mplayer and vlc itself.  This has been the case with every matroska file I have tried.

Reproducible: Always

Steps to Reproduce:
1. Download the official Matroska Test Suite here: http://www.matroska.org/downloads/test_w1.html
2. Open any of the videos in a phonon-based media player, such as dragon player or loopy

Actual Results:  
You get sound but no video

Expected Results:  
You get sound and video

test2.mkv does not work with smplayer but does work with vlc (but not phonon vlc).

It seems that audiodataoutput conflicts with video playback. Dragon in KDE 4.6 uses ADO to feed its analyzer. Testing with a minimal player without ADO works just fine.

Should be fixed in git master commit 9336affd8c806a934e4794ee632b0fa427907202

Reassigning to the new bugzilla product for better bug tracing of the various
backends. Sorry for the noise.
