[Ffmpeg-devel] [RFC] av_seek_frame behaviour

Here is my problem:

I request a seek to a specific timestamp at almost the end of file (MXF 
file), seek fails because it cannot find a frame to seek to, and returns -1.

Then av_seek_frame calls av_seek_frame_generic, and seek at the 
beginning of the file and starts reading all packets, until the end 
(basically demuxing a 10Gb file), which I'd like to avoid.

I think about always returning after demuxer seek function, see patch.
It might be wrong, and missed some demuxers behaviour.

What do you guys think ?
