demux: matroska: mkv files generated with GStreamer and streamable=true are not playable in VLC
A file generated with:
gst-launch-1.0 -e videotestsrc ! vp8enc ! matroskamux streamable=true ! filesink location=testsrc.mkv
fails to play with:
[00007f0780c02240] mkv demux error: unable to read KaxCluster during seek, giving up
[00007f0780c02240] mkv demux error: unable to read KaxCluster during seek, giving up
I'm not sure if this is a Gstreamer problem, a VLC problem, or both.
Note that it is playable with:
vlc --demux avformat testsrc.mkv
or if I generate the file without streamable=true
.
