Using Nvidia graphics acceleration to encode Motion videos

[crowl0gic]

I wrote a guide on how to offload video encoding to ffmpeg + an Nvidia graphics card via Motion's movie_extpipe function: https://github.com/crowl0gic/ffmpeg-nvidia

Contains an explanation of how to test your Motion video stream and ffmpeg commands so you can avoid the "event_extpipe_put: Error writing in pipe , state error 1: Broken pipe" error
