Description

I'm using FFMpegFrameGrabber to consume an rtmp live stream, that streams at 30fps, i tried to set the grabber frame rate using setFrameRate(4) and setOption("framerate","4") but neither worked.

Any help please?! Thanks

Contributor guide

Research direction
Investigate the implementation of setFrameRate() in FFMpegFrameGrabber and trace how the framerate option is passed to FFmpeg's avformat open input. Check if the option is being set correctly or if there is a conflict with the rtmp stream's existing framerate.
