Description Changwoo Ryu 2010-03-30 12:30:07 UTC 
flac-in-MKV files can't be played correctly.  All such files seem to have the same problem. An example file can be easily generated using flacenc and matroskamux:

$ gst-launch audiotestsrc freq=4000 ! flacenc ! matroskamux ! filesink location=a.mkv

After recording for a few seconds,

$ wc -c a.mkv
59372013 a.mkv
$ gst-launch filesrc  location=a.mkv ! matroskademux ! flacdec ! audioconvert ! alsasink
Setting pipeline to PAUSED ...

New clock: GstSystemClock
Got EOS from element "pipeline0".
Execution ended after 52340 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...

$

It just got EOS immediately. It can be played in other non-gstreamer players.
