Making the rav1d Video Decoder 1% Faster *on macOS with an M3 chip *slightly more than 1%, on a specific benchmark, without any new unsafe code A while ago, memorysafety.org announced a contest for improving performance of rav1d , a Rust port of the dav1d AV1 decoder. As this literally has my name written on it, I thought it would be fun to give it a try (even though I probably can’t participate in the contest). This is a write-up about two small performance improvements I found (1st PR, 2n

In March of 2023 we announced that we were starting work on a safer high performance AV1 decoder called rav1d, written in Rust. We partnered with Immunant to do the engineering work. By September of 2024 rav1d was basically complete and we learned a lot during the process. Today rav1d works well—it passes all the same tests as the dav1d decoder it is based on, which is written in C. It’s possible to build and run Chromium with it. There’s just one problem—it’s not quite as fast as the C version

When you jump into a video on YouTube or Netflix, a lot happens very quickly behind the scenes. Video data is rapidly downloaded to your device, which then has to unpack and normalize that information into a smooth, hiccup-free stream. The process of encoding and decoding video data has changed greatly over the years, with H.264 (AVC) and its succes
