Just want to document this as a known issue. Whenever ffmpeg-sys-next is being built, rustc dumps tons of warnings:

warning: `extern` block uses type `u128`, which is not FFI-safe
     --> .../binding.rs:...
      |
      | ... u128
      |     ^^^^ not FFI-safe
      |
      = note: 128-bit integers don't currently have a known stable ABI

This is rust-lang/rust-bindgen#1549, and above my pay grade to fix.
