Comment (by Arnaud):
Oh, OK.
Indeed that seems to be the problem in my initial file: only one IDR
frame.
Then I guess this bug can be closed, because there isn't much to fix on
ffmpeg library or on ffplay about it, don't you think?
If I'm right VLC uses ffmpeg, and I noticed it is able to seek this file,
but it seems like it reads all the frames from the IDR frame to achieve
this.
So I guess it's up to applications to implement such behavior on top of
ffmpeg's seek if not enough IDR frames are present.
Thanks a lot for your help :)
