Description
Apparently ffmpeg supports screen capture on Windows according to this: https://trac.ffmpeg.org/wiki/Capture/Desktop
Attempting to do so using:
FrameGrabber grabber = new FFmpegFrameGrabber("screen-capture-recorder");// As well as FFmpegFrameGrabber("UScreenCapture");
grabber.setFormat("dshow");
grabber.setFrameRate(30);
grabber.start();
Results in:
run:
Exception in thread "main" org.bytedeco.javacv.FrameGrabber$Exception: avformat_open_input() error -5: Could not open input "screen-capture-recorder". (Has setFormat() been called?)

This may possibly have something to do with(maybe???): https://trac.ffmpeg.org/wiki/DirectShow#Specifyinginputframerate
