Deprecated struct members in unstable Libav builds (e.g. AVStream.r_frame_rate)

Created by: michaeljoelphillips

Greetings,

I've attempted to install PyAV with pip as well as compile it from source and I get the following errors.

building 'av.video.stream' extension

I'm assuming I'm missing a dependency or something, but to the best of my knowledge, I have all of the correct development packages for the dependencies listed in the wiki. Any and all help is appreciated.
