building master fails

[the8472]

building ffmpeg master + ffmpeg sys master results in build errors. They're pretty much the same as are showing up on travis.

Building retrry/rust-ffmpeg@db95408164d278809b12e2e77ed90025ed6431ec works.

maybe @retrry forgot to make a PR for that?

I think @meh needs to release new rust-ffmpeg-sys version and change rust-ffmpeg dependency version. Now rust-ffmpeg depends on older version, without bingden changes.
