I probably cannot make it libavcodec-native because our goal with this
library is to add features and an API that is very specific to the
(video-conferencing / screen-sharing) we want to use it for.

The long-term plan is that after completing the inter-frame support, to also
add encoding, but that's still a few weeks ahead.
