About

What is this for?

To run ffmpeg on Raspberry Pi with the OpenMAX H.264 GPU acceleration enabled.

I built this to stream the webcam attached to my OctoPi to YouTube Live. There is nothing more excting then watching a live stream of a 3D printer laying down lines of plastic, right?

The Dockerfile is on GitHub adilinden-oss/docker-rpi-ffmpeg.
