I thought that -probesize and -analyzeduration were two different scales for
doing the same thing, one in file size and one in media playout duration.
Am I wrong ?

Anyway, I tried -analyzeduration 1000M, 1000 seconds while the default is 5,
and nothing changed.

And remember that the problem is that the number of detected input streams
decreases when the input file size increases, with a constant probe size and the
same beginning of media content. So, the analyzed data should be the same in
all cases. Am I wrong?
