Description

Not sure how to best describe the issue but :

grab http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_stereo.ogg

gst-launch-1.0 -e uridecodebin uri=file:///home/meh/Videos/bbb1080.ogg !\ theoraenc ! queue ! oggmux ! filesink location=rendered.ogv

Wait ten seconds and ctrl + C

Play back the file with vlc (gst-launch fails here with :

** (gst-launch-1.0:19343): CRITICAL **: gst_video_frame_map_id: assertion 'info->height == meta->height' failed) I think there's already a bug open about that.

The first second or so is "jumpy".

I assume the problem is in oggmux, as the issue doesn't happen with matroskamux.
