Hi all. I want to record a video using the camera and process individual frames before saving it to an MP4 file. So with VideoSink I get access to the raw frames in the OnSamples method and play around with them the way I want. Trouble now is I cant seem to be able to find out how to save the frames to file. With FileSink I can save the video to file but FileSink doesn't give access to the raw frames so I can't manipulate them. Does anyone know how to save these raw frames to an MP4 file.
