AV1 software decoding is already very intensive so AV2 decoding benchmarks are the next thing that would be really interesting (or mortifying) to see.

Yes, this is going to be fun to watch.

Because it's 5 times more complex, you need to get the maximum performance available. Therefore more ASM than ever.

Rust does not bring more performance. Just more safety.

I'm not sure what these two lines mean or if we can compare them, any help?

AV2 saves 25% bandwidth at the cost of 5x more decoding complexity.

Kyber | Low-level Developers and Sales | Paris area (hybrid) and Remote in Europe | Full-time | kyber.media

Kyber is an open-source SDK and platform to control remote machines, from Remote Desktop to Robots Teleoperation/Teleobservation.

Kyber is a multi-stream and multi-actuator transport in extremely-low latency, over Quic; it encloses the server, the client and the protocol.

One could use Kyber to control robots, drones, desktop, servers in the cloud or just remote rendering of interactive 3D programs. Kyber is done for Remote RealTime, where every millisecond matters.

Kyber is developed by engineers from the VLC and FFmpeg community, and we code in Rust, in C and in assembly. We have some development in Go too.

We're a quite technical team, but cool to work with.

And all this article is "just" about the building of the Java/Kotlin application :)

Native NDK is another can of worms, with updates linked to SDK or sometimes not, unclear documentation about device and API compatibilities, compiler behavior changes and other requirements (like the 16K one) that impact so many 3rd party native libraries.

But, of course, the rules on the uploading and the changes of the Console, that changes so often is what makes it painful.

The absolute nightmare is about giving Google the root signing key of your application, the unfinished business about app bundles (which should reduce the size of the downloaded app, and more often than not, make it bigger), the changes in compliance, letters to sign for different countries, the compatibility for Google form factors (XR, TV, Auto, Automotive), Inline installs and other Teacher Progams, Play for family and so on.

All of this changes non-stop and is very poorly documented :)

At least, the Play Store is still GPLv2 compatible, so for now, we're saved (VLC)

(President of VideoLAN here).

So far, VideoLabs is hiring most of the VLC core developers and those people are the main force of development of VLC. It's setup this way so that if the Videolabs company does not live forever, VLC stays forever free, and the non-profit lives.

This is quite classic of open source projects, and in the case of VideoLAN, there are 3 or 4 companies doing consulting.

I documented that a bit that, in the past: every ODD.1 release is LTS.

And the LTS is maintained at least as long as the next LTS is, and should be at least 3 years.

So, for example, we support 5.1 and 7.1 as LTS. And we support 6.1 and 4.4 as best effort.

Does this "Vulkan based encoding" mean we'll be able to get the best of both worlds?

Unlikely. This is just a generic API to the same GPU backends; so you will not see more quality than nvenc.

The worst is that Telegram Secret Chats are limited in functionalities, compared to the normal ones, for no reasons. Stickers set don’t work, for exemple, and that’s one of the main feature of Telegram chats.
