Hardware Acceleration H264 encoding

[evilbunny]

On the RPi3, I didn't do it real-time, but used the h264_omx hw encoder, with ffmpeg. It worked pretty well, besides the amount of time required.

While there is hardware support for encoding, the software is lacking, you may want to consider the Rockpro64, although linux support is still being worked on at this point in time.

I make timelapse videos from an IPcam which gets a jpg every 20s, the r64 takes about 15minutes to complete, the rp64 only took 5 minutes. Once tweaks are in the performance should be even better.
