 └───────────────────────────────────────────┘

   The FFmpeg Project proudly presents FFmpeg <next> "FIXME", ...
   FFmpeg 2.4 is API-, but not ABI-compatible with the previous major release.
   This means that the code using our libraries needs to be rebuilt, but no
   source changes should be required.
