  3. …see it very often in codec implementations. From rav1e, a fast AV1 encoder mostly written in Rust: https://github.com/xiph/rav1e/tree/master/src/x86 Portions of the algorithm have been translated into assembly for ARM and x86. Shaving even…

  13. …In the end, I am quite happy with the tiling structures API, but a lot of work (and [boilerplate]( https://github.com/xiph/rav1e/tree/f1c43dbdc52016f67ecf33383... ) was necessary to implement them.

  16. …which is critical for something like WebRTC. For example, rav1e still needs multithreading support: https://github.com/xiph/rav1e/issues/132 And once encoders are ironed out, hardware support is also needed.

  19. There are some: https://github.com/xiph/rav1e The projects behind this project are all in C, so I imagine that’s why. They probably don’t want to commit to Rust on the basis of this codec alone.
