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:
{{{

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.
