[FFmpeg-devel] mpeg fixed frame rates (ffmpeg faq 1.14) or code

[Makc]

Hello.

In ffmpeg faq it sais:

"Some codecs, like MPEG-1/2, only allow a small number of fixed framerates"

I would like to know (the place where I can find) the list of these
frame rates for these "some" codecs.

Or, it would be nice if you would pin the place in ffmpeg code that
deals with this situation, so I could learn thing from there on my
own.
