Scott Lamb 62a1bad8b9 third attempt at travis config
* upgrade minimum required Rust from 1.17 to 1.20; reffers 0.4.2
  apparently uses std::mem::ManuallyDrop, introduced in 1.20

* install ffmpeg from source (requiring sudo access) rather than using
  the ancient one from Ubuntu Trusty to meet the minimum version
  requirements specified in ffmpeg/build.rs.
