(Cloned): Updated FFmpeg version and Linux build

FFmpeg was updated to compile from the git master and the alphine set to latest. Most of the config is still the same.

HOWEVER

This is now a 140MB image, rather than 109MB.

This is just the form from: https://github.com/opencoconut/ffmpeg, original README below the line.

Minimal FFmpeg Docker image built on the latest Alpine Linux

Current FFmpeg version: master

Usage

$ docker run opencoconut/ffmpeg -i http://files.coconut.co.s3.amazonaws.com/test.mp4 -f webm -c:v libvpx -c:a libvorbis - > test.webm

To encode a local file, you can mount the current path on the Docker host's filesystem as a volume inside the container like this:

$ docker run -v=`pwd`:/tmp/ffmpeg opencoconut/ffmpeg -i localfile.mp4 out.webm

You can create an alias so you use the Docker container like if FFmpeg is installed on your computer:

In ~/.bashrc:

alias ffmpeg='docker run -v=`pwd`:/tmp/ffmpeg opencoconut/ffmpeg'

Now we can execute FFmpeg with just:

$ ffmpeg -buildconf
