If you are unfamiliar with the AV1 codec well it is the successor to VP9 which was in the same class of h.264 which was and still is prolific on the internet. AV1 is a big jump over h264...
MediaTek was early to implemented AV1 in their Dimensity smartphone chips since 2019. And if you aren't aware those are in a lot of Chinese smartphones.
There is now a decent chance you own and use a device that supports AV1 decoding. This means that AV1 I think is going to take over the internet in the next few years.
Although AV1 is free and open source, it is a result of corporate socialism and Google's CIA influence. It probably wouldn't even be possible in the capitalist framework otherwise because big surprise intellectual property isn't actually good for innovation or much else.
