Score: 5.5/10 (Innovation: 5, Technical: 8, Documentation: 5, Utility: 4)

rav2d is a Rust port of the dav2d AV2 video decoder, aiming to provide memory safety and bit-exact decoding using a hybrid approach of FFI for optimized assembly and progressive C-to-Rust translation. It is notable for its focus on correctness and safety in video decoding, leveraging a proven strategy from the rav1d project, though it is still in early development and not production-ready.

Target audience: backend devs, systems programmers, multimedia engineers
