first try

So, the attached patch implements rude FPS detection, which works OK for some
movies. However, for others, it doesn't work at all. Reason is timestamps in
ASF:

Time: 0:00:29.666000000
Time: 0:00:29.733000000
Time: 0:00:29.800000000
Time: 0:00:29.866000000
Time: 0:00:29.933000000
Time: 0:00:30.000000000
Time: 0:00:30.066000000
Time: 0:00:30.133000000
Time: 0:00:30.200000000
Time: 0:00:28.352000000
Time: 0:00:30.333000000
Time: 0:00:30.400000000
Time: 0:00:30.466000000
Time: 0:00:30.533000000
Time: 0:00:30.600000000
Time: 0:00:30.666000000
Time: 0:00:28.928000000
Time: 0:00:30.800000000
Time: 0:00:30.866000000

I don't know how come, but video is way ahead of audio. Also, it's very choppy,
probably for the same reason (i.e. sometimes it processes 10 frames in a snap,
sometimes it hangs for a second). Apparently, the early timestamps are
I-frames, and are wrong, but because they are I-frames, ffmpeg uses them as
base for timestamping. I'll need to see how other apps solve this issue.
