20k Bounty: Help Achieve Parity Between Rust's rav1d and C's dav1d AV1 Decoders!

The rav1d AV1 decoder, written in Rust, is currently about 5% slower than its C-based counterpart, dav1d. To bridge this performance gap, a $20,000 bounty is offered for contributions that bring rav1d to performance parity with dav1d. Improvements can be made to the rav1d codebase, the Rust compiler, or the Rust standard library, but modifications are subject to specific rules (no modifying low-level assembly, no non-Rust code). The bounty will be distributed proportionally based on the performance improvements achieved.
