There seems to be multiple people at videolan dunking on rav1d, in notable part due to how it was done (transpile C to Rust, and cleanup afterwards). Perhaps they're Rust purists and don't think that's how it should have been done. Or perhaps they're not happy that rav1d proclaims that Rust is (almost) as fast as C when all the performance engineering efforts went in the ASM bits, that were copied verbatim from dav1d.

My best guess would be for the same reasons the ffmpeg twitter account has shown a lot of vitriol too: funding taken away from the original project towards another effort.

Alternative phrasing: "funding originally applied to one project benefiting multiple efforts". It's sad to see people from open source doing... gatekeeping? jealousy? something...

Alternative definition of outsourcing: the salary originally applied to one person in high cost country benefiting multiple people in low cost country :)

But… why high cost country developers jealous?

This is key. Not to mention how advocates for ra1vd are gaming their benchmarks and obscuring how unsafe the actual code is. The bounty presenting it as "safe" on memorysafety.org is a laugh.

IMO, that dishonesty deserves some snark from VLC and ffmpeg.
