[FFmpeg-devel] [PATCH] Incorrect ASF duration

[Henrik Gulbrandsen]

This is similar to the Ogg problem. The stream duration is not identical
to the PTS of the last packet if the packet duration is non-negligible.

The attached examples show the result of

    ffmpeg -i video.mp4 -vcodec wmv2 -f asf video.wmv
    ffplay -stats video.wmv > report.txt 2>&1

before and after the patch. As before, video.mp4 is exactly 24 seconds
long, at 10 fps. Notice the "Duration: 00:00:23.90" for stats given with
the current code base!

P.S. I removed the "use duration from AVPacket" comment, since the patch
is in fact using that duration. It looks like this comment has been with
us for a while, and I don't really know what the original intention was.
