OPENCV Solution

GPU slower then CPU. This also seems to be the behavior at https://github.com/chenxinfeng4/ffmpegcv

Build

docker build -t ernestlwt/opencv_reader:gpu_h265 opencv/.
docker build -t ernestlwt/opencv_reader:gpu_h264 --build-arg CODEC="h264"  opencv/.

docker build -t ernestlwt/opencv_reader:cpu -f opencv/Dockerfile.cpu opencv/.
