Rounded FPS

[pozitronik]

It seems that when source FPS is fractionary (e.g. like 29.97004) and target FPS is the same, any h264/h265 encoded videos have the same problem with broken rewind in the end part of the target video. The solution is to round up FPS values by default.

That problem may be not linked with fractionary FPS, but with methods of the frame extracting itself. Frames are extracted using CV2, but resulting video is always made with ffmpeg, and so there can be the source of the problem.
