[FFmpeg-devel] [PATCH] libavformat/matroskadec.c: Parse stream durations set by mkvmerge and populate them in AVStream.

[Sasi Inguva]

Ok. i'll drop this patch . Does outputting stream DURATION values in
matroskaenc.c  as string tag's , (same as mkvmerge does ) seem ok?  Atleast
then, I can parse those string metadata in our own video pipeline  which
will solve my use case.
