I'd have to look into how this specific ffmpeg comand works (in extractFrame) but I'm guessing you probably wouldn't want to be spawning a new process for each frame because of the overhead. There should be an option to be able to a range of frames in a single process.

I have a follow-up to address this with an optional setting, but it depends on code in the other branch landing first (the multi-camera option)
