Which is something like a "5.3x" display, such as lame shows it (I
think).

I think that is just as valid a request for video. I do see the fps,
but I need to do quick head-math and know the fps of the source.

That said, there may be some ambiguity with regards to which base to
take: Input PTS, output PTS; what about jumps in PTS? Can this work
when copying? I'm thinking out loud too much. ;)
