RE: [xine-devel] PATCH, to use fps from ffmpeg

[James Courtier-D. <Ja...@su...>]

I don't know too much about asf format, but I assume it will be similar to
mpeg2 in some respects.
In mpeg2 the fps or frame_duration is found out at the decoder stages, and
not the input or demuxer stages.
Cheers
James
