In a previous issue the following options where given as working with FFmpegFrameRecorder and I am assuming the same goes for FFmpegFrameGrabber. Though it would be great to have a full list of options that work. For my part I would like to know whether the loglevel option can be set or not? (I tried setting the option, but it did not change anything)

setOption() is for at least the following options:
https://ffmpeg.org/ffmpeg-formats.html
https://ffmpeg.org/ffmpeg-protocols.html
https://ffmpeg.org/ffmpeg-devices.html
but maybe others too.

setAudioOption() and setVideoOption() are for the options here:
https://ffmpeg.org/ffmpeg-codecs.html

That should be better documented probably in the API docs with Javadoc,
so please send a pull request to that effect! Thanks
