[MPlayer-dev-eng] [PATCH] demux_lavf should consider start_time when calculation percentage bar

[Reimar Döffinger]

Hello,
currently with some files (e.g.
http://ktown.kde.org/akademy/Scott_And_Christian_GStreamer_video.ogg)
the position bar never drops below half-full with -demuxer lavf since
the stream starts with a timestamp of 1 hour.
The attached patch fixes this for the cases where libavformat sets
start_time correctly (for above file in combination with the patch I
recently sent to ffmpeg).
Ok to apply?

Greetings,
Reimar Döffinger
