building on Ubuntu 12.04

Created by: mkassner

On 12.04LTS I cannot resolve all dependencies for installation with just apt-get. I always get an error complaining about audio_fifo.h not being present. I suspect that I was missing libswresample and it seems that libswresample is not available for 12.04.

I can build pyav by building ffmpeg and many of its dependencies from source as shared libs. Since this is actually quite involved I have modified an existing shell script. You can find my version here for referece: https://gist.github.com/mkassner/1caa1b45c19521c884d5

I find this to be a bit crazy and hope that there is a faster way of getting pyav working on 12.04 (on 14.04 APT can be used to resolve all dependencies)

Suggestions?
