This is a OpenCV + python Dockerfile useful for doing image analysis.
this has an ffmpeg older than the containers i've made with ffmpeg. don't use for audio processing especially not for preparation for streaming / mobile use. use one of them -- https://hub.docker.com/r/corprew -- if you need ffmpeg.
OpenCV is seriously huge when compiled. may be faster to build this one from the dockerfile on github depending. -- https://github.com/corprew/opencv-python-docker
The run command for this is interactive python. import cv2 to add OpenCV's python extensions.
