[Bug 792775] matroskamux wrong timestamps

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=792775

--- Comment #6 from Nicola <lists at svrinformatica.it> ---
the sample file has the second keyframe after about 9 minutes and 40 seconds,

obviously a such file will cause problems in pipelines such as this one

gst-launch-1.0 -v filesrc location=/tmp/sample.mkv ! matroskademux !
matroskamux streamable=true ! tcpserversink host=127.0.0.1 port=3000 sync=true
sync-method=2

if you connect with tcpclientsrc after 32 seconds that the tcpserversink
pipeline is running you will not be able to see the video: a new matroska
cluster is started because the max duration was reached and it does not start
with a video keyframe, maybe we should set the discont flag in this case. I
guess this will cause seeking issues too
