Setting custom frame rate FFmpegFrameGrabber about javacv

[saudet]

This is mainly a problem with FFmpeg I fear. When capturing from a camera, for example, we can for example ask it to set the frame rate to 22 FPS, but if the camera doesn't support it, it sets it to the nearest supported value, say 25 FPS, and returns that. In the case of video files, the value is simply ignored, but I don't see a way to query whether the value gets ignored or not. Do you know of some functionality in FFmpeg that would let us query this state? Thanks!

If I do I'll write about it here. But i think now that... maybe current solution isn't so bad and whole problem dosen't in fact require so much effort... I did some changes in my code, and added this method:

public void setUserFrameRateRatio(double customFrameRate) { //value from range 0-1
this.userFrameRateRatio = customFrameRate;
}
//some code later...
//oneFrameTime = 1000 / grabber.getFrameRate(); // old solution
//new solution:
oneFrameTime = 1000 / (grabber.getFrameRate()*getUserFrameRateRatio());

...and that's enough to control whether movie should be playing slower or faster than in original (and by the way I still can get infos about oryginal FPS from .getFrameRate()). So what about just some kind of function which will return oryginal FPS "scaled" (or modified in some smarter way) by user e.g:
setScaledFrameRate(double scaleFactor /* Or maybe how much FPS should be added to oryginal value or smth. similar..*/);
and getScaledFrameRate(); ?

Well, like you say this can easily be added in the player's code, so I don't feel we need to have this in the grabber itself.
