VideoLAN Announces Dav1d, a New Libre and Open Source AV1 Decoder (jbkempf.com)
Jean-Baptiste Kempf, president of VideoLan and developer of VLC media player, made the following announced Monday: AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,...). AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing.
The reference decoder for AV1 is great, but it's a research codebase, so it has a lot to improve. Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media. The goal of this new decoder is: be small, be as fast as possible, be very cross-platform, correctly threaded, libre and (actually) Open Source. Without further due, the code: https://code.videolan.org/videolan/dav1d Recommended: A talk during VDD 2018 conference about dav1d.

By the way, what is the "Code of Conduct" for this software? Something that will make Linus tuck in his tail and go a hide from all humanity?"
a patent troll magics up some patent relating to AV1 ?
So they can tell you what you can do with it.
The most important things are:
- Is the code inclusive?
- Is it written by women?
- Any cis-gender hetero-normative white males involved?
If those important issues are not given proper care we can't accept any code from this project.
composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,...)
So I assume it contains spyware that collects data on you and sends it back to them?
Yes, this story is about a decoder. But what good is that without content? AV1 is so much more computationally expensive that H.266 will come and go in the meanwhile. No company will pay to get their content created in AV1 format when there are alternatives that are good enough. Itâ(TM)s going to be years before this sees the light of day. This is a political game more than anything, but itâ(TM)s doing a good job of stirring up the OSS zealots.
When one isn't fluent in English, either because it's not the primary language or because one is an idiot incapable of being fluent in any language, the result is minor mayhem like replacing "without further ado" with "without further due".
Why do Slashdot editors exist at all, if not to maintain that fluency when submitters cannot?
I remember when the same "trouble" was in the news, with regard to H.264 and the various MPEG containers.
Meanwhile, the entire file sharing community already used H.264 and Matroska with all its luxuries.
It took years, before Google also started using Matroska, albeit its stupidly crippled form, webm.
Nowadays, everyone already uses H.265. ... Nobody cares.
With regard to the licenses
Because frankly, if they want real actual money, where I had to work another bit for every bit of money I got, in return for giving me the "right" to merely use an idea "they" partially came up with, based on the free work of others, with a one-time bit of work ... then all they are gonna get in return from me, is that I mirror them exactly, and expect them to work and come up with another better codec format, every time I give them a mere copy of those $100 I "worked hard for" that one time. And yes, I will wall them "pirating thieves" too, if they refuse to take my worthless funny money. And sue them on the grounds that by not giving me free shit, they effectively stole from me. ... You know. Content Mafia "logic".

For all intensive purposes, this has peaked my interest in one foul swoop.
Those who do not learn from commit history are doomed to regress it.
This decoder needs to replace the arithmetic coding by one better ANS coding (invented by Jarek Duda) that has a good speed as Huffman's and a good ratio as Arithmetic Coding's.
do we still need to squeeze every last byte out of video files given how big our storage devices have gotten to be and how fast our networks are getting to be? or what about a decade from now? or is this going to be a cause for compression for the next millenium?
now we need to go OSS in diesel cars
AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,...).
I would have added "developed" or "written" or "created" before "by", but whatever, I'm busy figuring out how a codec is composed of "most of the important Web companies" or why we're capitalizing "Web".
AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing.
I'm going to give you a pass on the unexplained "better", and "the patents license" may be an awful Britishism that I'll ignore (for now), but if the HEVC "patents licenses" are "insanely high", isn't that a problem? Are they going to go out and announce that they're taking HEVC public at $420?
The reference decoder for AV1 is great, but it's a research codebase, so it has a lot to improve.
I'd throw in "based on" or "compiled against" before "a research codebase", and probably throw in an "on" after improve (or rewrite it so there's no preposition at the end of a sentence, though I never found that to be a logical rule). However, the big concern here is that you're calling the reference decoder "great" while simultaneously saying that it isn't.
Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media. The goal of this new decoder is: be small, be as fast as possible, be very cross-platform, correctly threaded, libre and (actually) Open Source.
You shouldn't be capitalizing "Open Source" here, and something being "very cross-platform" doesn't really fit, unless you're talking about a waffling politician. Can we at least agree on quantity, though? You've listed more than one goal. You want "goals" and "are".

It's "without further adieu", you clown!
I had to downgrade from v3 to v2 because whatever they did to the interface has completely fucked it up.
I think you mean, "ado."
