           Summary: matroskademux: wrong H.264 demux in some file

            Status: UNCONFIRMED

I found a H264 video which was not played correctly. The matroskademux element
seems to lost some H264 data. I made a short sample (~7MB, about 12 seconds):

http://people.debian.org/~cwryu/bugs/gst-matroskademux.mkv

With the following command, video stops after about 5 seconds from the start. 

$ gst-launch filesrc location=gst-matroskademux.mkv ! matroskademux !
ffdec_h264 ! ffmpegcolorspace ! xvimagesink

It can be played correctly using ffdemux_matroska instead of matroskademux .

$ gst-launch filesrc location=gst-matroskademux.mkv ! ffdemux_matroska !
ffdec_h264 ! ffmpegcolorspace ! xvimagesink
