1.26 doesn't work with the updated rusqlite:
error[E0658]: use of unstable library feature 'duration_extras' (see issue #46507)
--> /home/travis/.cargo/registry/src/github.com-1ecc6299db9ec823/rusqlite-0.14.0/src/busy.rs:26:49

26 | .and_then(|t| t.checked_add(timeout.subsec_millis().into()))
| ^^^^^^^^^^^^^
1.25 also fails with the upgraded reffers because u128 isn't stable:
error[E0658]: 128-bit type is unstable (see issue #35118)
--> /home/travis/.cargo/git/checkouts/reffers-rs-0d00fc7f893338b3/49a4d75/src/rc_bitmask.rs:194:34

travis-ci pointed out that building with 1.21 broke with a recent dep
upgrade (8c52c36). reffers now uses nested groups of imports, which is a
feature introduced with Rust 1.25. Prior to 1.25, it fails as follows:
error: expected one of `,` or `as`, found `::`

* upgrade min required rust to 1.21; crossbeam-deque requires the
ord_max_min feature, apparently stabilized in this version.
* use "make --jobs=2" to build ffmpeg so it goes faster.
https://docs.travis-ci.com/user/reference/overview/ says there are 2
cores available.
* 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.
