Worth a try but I see two (potential) problems: * is it hardware accelerated? it says it uses ffmpeg in the backend and that, to me, sounds like it's not using the OMX interface for hardware accelerated video on the pi * it requires jack, this means you're increasing overhead by running the jack server
