By reading the features of the AV1 codec and its support on sites such as YouTube and Netflix. And I came across an article on how to use it through FFmpeg, but this is not the main thing. I came across a link to a new encoder under the name "rav1e", which, by assurance, is faster than the current one.
I understand that in its current form it is not perfect. True, I would like to see in future builds.
I was not able to build it with "Rust" so far ...
