FFmpeg

Building

To build just run:

./build.sh

This should give you a docker image with devtoolset3 installed in order to keep binary size down. Outputted binaries should be in the output folder

Pushing

Once you have built the binaries push them with:

anaconda upload -u pytorch --force output/*/ffmpeg*.bz2

If you do not have upload permissions, please ping @seemethere or @soumith to gain access
