DAV1D: A New AV1 Video Decoder From The VideoLAN Developers

[pal666]

It baffles me why people write new security-critical software in C in 2018. Especially something as notoriously prone to memory errors as video decoder. Rust should have been a no-brainer.

because rust fanbois do not write software, they just parrot on forums

we don't, youtube encodes videos without our help

WTF?
I need to encode MY videos. There is a world besides Youtube, incredible as it may sound.

that world is tiny compared to streaming, so we do not need encoder. it would be nice to have, but not required

Firefox is already in the process of using dav1d as the default decoder : https://bugzilla.mozilla.org/show_bug.cgi?id=1493397

Nope. There are already fully functional multimedia decoders in Rust that perform within 10% of the reference implementations:

Vorbis: https://github.com/RustAudio/lewton

FLAC: https://github.com/ruuda/claxon

As opposed C+assembler in reference implementations, this is pure Rust and it's still within 10% performance margin.

An MP3 decoder is notably missing because even though the patents have expired, the relevant standards are not public and are not that easy to get your hands on. Still waiting for that one.

Firefox's production MP4 parser is in Rust: https://github.com/mozilla/mp4parse-rust

Plus there are zillions of imaging libraries, including for obscure things like FLIF, because encoding/decoding images is just easier to implement than audio or video. Won't list them all here.

So what is the point you're trying to make? That we should all just happily consume youtube (which of course I do too) but never dare trying to create something, least of all if it - oh the horror - doesn't involve youtube at all?

rav1e is written in Rust by the same guy who wrote Vorbis in C.

i like the name

Oh it's both handsome and witty alright, but amidst all this excitement, don't forget to change your root password. ;-)

Michael have/will you looked in benchmarking this or using it as a benchmark?

[Adarion]

Nice, also the name (D-AV1-d vs Goliath and so on).
But +1 for encoder and HW accelerated de/encode.
