VideoLAN's president, jbkempf, was considering finding manpower to build an AV1 implementation a couple months ago. Not sure of the status now.
- jmvalin 9y agoThere's already a Rust AV1 encoder project you might want to look at: https://github.com/xiph/rav1e https://github.com/xiph/rav1e
- BTeam 9y agoIndeed! This implementation was started by some people working on AV1 to test libaom's specification implementation correctness. There was a presentation about it at VDD17, if I remember correctly.
- FullyFunctional 9y agoInteresting, but since I could conceivably be exposed to a malicious AV1 stream, I'd value a Rust AV1 decoder even more (which might exist, I don't know).
- TD-Linux 9y agoThat's a very good point. I chose Rust more to get ergonomics and more reliable threading - security was not the primary motivation. That said, the encoder is exposed directly to the web via the MediaRecorder API.
- lossolo 9y ago> There's already a Rust AV1 encoder 80% of codebase is C. How is that Rust encoder? Seems like a binding to C AV1 encoder.
- jmvalin 9y agoThe C part is mostly for low-level functions and was brought in to help bootstrap development (it's easier to work on improving a working encoder than one that doesn't work yet). The amount of Rust code is expected to increase a lot over time, while the amount of C code is expected to either decrease or remain constant.
- TD-Linux 9y agoThe github counter is misleading - it is counting auto-generated C headers used for calling assembly code. The repo also contains a libaom submodule, but the only parts that are used are initialization tables and the transforms.
- FullyFunctional 9y agoThis hits me too on some projects of mine. Infuriating. I find wrong stats worse than no stats.
- milesrout 9y agoThe stats aren't wrong. If it isn't 'real code' then you shouldn't store it in your repository, you should autogenerate it as part of your build process.
- themihai 9y agoIsn't AoMedia supposed to provide a reference implementation? Is there any reason not to use it (an patch it along the way)?
- ComputerGuru 9y agoIt’s crap and slow as molasses built off an inferior earlier encoder’s codebase. It proves the concept, but it’s not something you want to need rely on in production.
