I only tested the other one. I guess for the mp3 the AV_NOPTS_VALUE
makes it being accepted no matter where you seek to.
But you could consider the mp3 working as much a bug in itself.
Now for why MPlayer can't seek: The problem is that in an attempt
to get the next video frame MPlayer demuxes the whole audio of the file.
Thus only seeking backwards works, seeking forwards will exit (this
is due to seeking being relative to the demux position instead of the
current playback position).
