This Dockerfile helps create an automated build inside a debian container.
The purpose behind this is to build ffmpeg inside a debian container.
Then the next step is to export the compiled binaries into an untouched base debian image
See my other repository "ffmpeg" @ https://hub.docker.com/r/nachochip/ffmpeg/
This results in a ~50% reduction in image size.
FYI: this image is useable....I just like having a smaller base image to download.
docker run nachochip/ffmpeg -i INPUT -vcodec copy -acodec copy - > OUTPUT.mp4
This container uses the entrypoint="ffmpeg"
