In the source tab of a camera source there's a field for options to pass to ffmpeg. However the examples aren't command-line flags, and if I enter a CLI flag there I get either a parking error or an error that ffmpeg doesn't recognize the option. So, what options are intended to be passed via that field, and where else would I pass a CLI option?
I'm trying to experiment with the -hwaccel flag.
