[Ffmpeg-devel] [PATCH] MXF duration improvements

Hello,
the attached patch sets the default duration (when no such info is found
in the file) to AV_NOPTS_VALUE instead of 0.
It also sets start_time to 0 by default. I'm not 100% sure if that is
correct, but otherwise AVFormatContext.duration does not get set
and MPlayer can not display the total time.

Gretings,
Reimar D?ffinger
