I've used some of them both on Windows and OSX, afaik they are only usable with the software provided with them not with ffmpeg, although i seem to remember there where some efforts to get things going under linux.
With the provided software speed is Ok on an Atom, but quality is NOT, much less configuration possibilities then ffmpeg. Especially quality based encoding, -crf, is missing. I do have 2 of them if you're interested they are for sale.
