2211	Not possible to override bogus FPS in raw h264 streams	jaanusk		"It's not possible to override fps on raw h264 streams.

For example, I have a stream produced by Raspberry PI HW encoder which plays fine when fps
is forced. The actual fps is 15, but recent ffmpeg versions default somehow to 25fps.

How to reproduce:
{{{
% ffmpeg -r 15 -i stream_00 -vcodec copy stream.mp4

Output file plays faster then normal because the actual source is 15fps and ffmpeg does not allow to override this.

Last version that works as expected is 0.11.2.
