Ask HN: Why does nobody support h.265/HEVC anymore? (Score: 150+ in 18 hours)
Link: https://readhacker.news/c/5ckBP
It seems that right now there is no browser that supports h.265/HEVC even on hardware that can decode it - "Old Edge" used to, but "New Edge" does not. Neither Chrome nor Firefox support it (actually, both of those refuse to use any form of hardware decoding at all on my Windows box, only Edge uses it for VPx and h.264 - and of course every media player).
The only exception is Apple with Safari.
Why is this? h.265 can do a lot better than h.264 in some scenarios, but certainly isn't worse.
And why, oh why, is debugging hardware video acceleration still such a nightmare, even on Windows? Firefox doesn't even seem to have it in about:support any more!
And why is hardware video acceleration only a problem with browsers? I've never had any kind of problem with it with any media player, regardless of OS. It just works. But browsers - it seems to never work OOTB. Except for Edge, apparently. Which I thought was just a Chromium reskin with MS tracking.

Anyways, yearly reminder that software patents are a blight to innovation and a scourge on our industry, and no you won't change my mind. - akersten

VLC 为什么能免费播放 HEVC？
按照官网说法，因为 VLC 是法国组织 只遵照法国法律，而法国法律和欧洲专利公约均认为，软件本身不能作为专利。
> VideoLAN is an organization based in France.
> Therefore, most of the following page is redacted in French and refers to French law, which is the only one to be applicable to VideoLAN.
> Neither French law nor European conventions recognize software as patentable.
> Therefore, software patents licenses do not apply on VideoLAN software.

Can you be awake and asleep at the same time?
Many animals need sleep. But all of the threats and demands animals face don't just go away when it's time to doze. That's why a range of birds, mammals, and even humans experience some degree of asymmetrical sleep, where parts of the brain are asleep and…

Congrats to @Google for getting Arabic script backwards & disconnected during @sundarpichai's presentation on *Google Translate*, because small independent startups like Google can't afford to hire anyone with a 4 year olds' elementary school level knowledge…

RT @karmchaari: Besides Arabic script, many other scripts are rendered broken here too. If I were someone who used any of these languages, seeing this would not inspire much confidence… #GoogleIO2022

I made a helpful annotation for everyone. Every single one that's not Latin- or Cyrillic-based is wrong (at least a little bit).
I struggled a bit with displaying the Bengali script, but I made it work better than did this "Google" startup, whatever that is

英伟达发布了开源 GPU 内核模块
NVIDIA is now publishing Linux GPU kernel modules as open source with dual GPL/MIT license, starting with the R515 driver release. You can find the source code for these kernel modules in the NVIDIA Open GPU Kernel Modules repo on GitHub.
……
Along with the source code, fully-built and packaged versions of the drivers are provided.
For data center GPUs in the NVIDIA Turing and NVIDIA Ampere architecture families, this code is production ready. …… In this open-source release, support for GeForce and Workstation GPUs is alpha quality. GeForce and Workstation users can use this driver on Turing and NVIDIA Ampere architecture GPUs to run Linux desktops. More robust and fully featured GeForce and Workstation support will follow in subsequent releases and the NVIDIA Open Kernel Modules will eventually supplant the closed-source driver.
Customers with Turing and Ampere GPUs can choose which modules to install. Pre-Turing customers will continue to run the closed source modules.

Most features of the Linux GPU driver are supported with the open flavor of kernel modules, including CUDA, Vulkan, OpenGL, OptiX, and X11. However, in the current release, some display and graphics features (notably: G-SYNC, Quadro Sync, SLI, Stereo, rotation in X11, and YUV 4:2:0 on Turing), as well as power management, and NVIDIA virtual GPU (vGPU), are not yet supported. These features will be added in upcoming driver releases.
