Build

First you need to install docker on your local computer, see following tutorial. Note, for running the docker properly you have be logged as superuser otherwise you will face many partial issues which sometimes does not make much sense.

You can build it on your own, note it takes lots of time, be prepared.

git clone <git-repository>
cd docker_python-opencv-ffmpeg
docker image build -t valian/docker-python-opencv-ffmpeg -f Dockerfile-py2 .

To build other versions, select different Dockerfile.

Other option is using already build image from DockerHub which is significantly faster. it basically download the already build image.

docker pull valian/docker-python-opencv-ffmpeg

Usage

Image has OpenCV3, python2.7/3.5 and ffmpeg ready to use. Example:

docker run --rm -it -v $PWD:/srv valian/docker-python-opencv-ffmpeg
>>> import cv2; cv2.VideoCapture(0).read()
# truncated for transparency
(True, array([[[ 0, 43, 37], ...]], dtype=uint8))
