This PR makes Travis builds about 15X faster. It installs the dependencies, including FFmpeg, from binary conda packages instead of source.
The packages are downloaded from a new community conda channel where I uploaded FFmpeg, x264, and pkg-config. (We need a conda-installed pkg-config, not system pkg-config, to see the libraries of conda-installed FFmpeg.)
We can also upload packages for PyAV itself. I put some on my personal conda channel to try. @tacaswell and I tested this on OSX and 64-bit Linux. There are packages for Python 2.7, 3.3, and 3.4.
conda install -c danielballan PyAVThat one line takes care of everything. The installation instructions could get a lot simpler!
