This cannot work.

When a libav feature is merged into FFmpeg, the FFmpeg version is *not* 
changed (since it is already incorrectly higher). Hence, there is no simple 
way to support FFmpeg versions with #ifdef, except for stuff that is only in 
FFmpeg and missing in libav.

FFmpeg versioning is just totally broken. When you set yourself up as a 
downstream, you have to use *separate* version numbers. Patching upstream's 
number cannot work.
