Dockerfile

# Install the transcoding tool. The node will be accessible via HTTP on port 8100 and the cli tool will be on the path. The port can be changed.

# This image will be created to use an entrypoint. If you need to create a container 
#   with a shell you can run:
#
#    docker run -i -t -entrypoint='/bin/bash' rethinkdb -i
#
#    Just keep in mind that's giving you a shell in a new instance of the image not 
#    connecting you to an already running container.
#
#
#    Otherwise the main use of the file is:
#    docker run transcoding \
#            320p \
#            -i sample.mp4 \
#            -o output.mp4
