[Bf-committers] Misguided maximums on fps, fps_base?

[Bassam Kurdali]

rather than attach I linked as my smaller videos didn't exhibit the
problem.

I don't think anything is wrong with ffprobe. It just looks like some
videos try to use integers for both fps and fps_base (and since 1.001
is the typical thing it multiplies them both by 1000) I've seen this on
quite a few videos but most are from a client and I cannot share.

The 120 limit doesn't really make sense on a ratio.
