AV1 does really work great to hide artifacts at this low bitrate situations so this is a great use case for it.
I guess if stadia will switch to AV1 they will use FPGAs to stream it in real time. nvidia did tease that twitch is working on 1440p120fps AV1 trancoding https://www.nvidia.com/en-us/geforce...-av1-decoding/ Twitch did work with NGCODEC on VP9 trancoding https://blog.twitch.tv/en/2018/12/19...-35db26f6322f/
So i guess they will do the same with AV1 (I think the streamer will still stream with h.264 and twitch will do AV1 in the trancoding steps)
Here a talk from NGCODEC about that work(NGCodec was acquired by Xilinx in July 2019) https://www.youtube.com/watch?v=vcuQuQAX4gU
Not sure if AV1 as Live streaming codecs(Software encoding on the CPU) is the right choice yet https://openbenchmarking.org/test/pts/svt-av1 That are big CPUs with a lot of cores for 1080p in this test(this are results for svt-av1 0.8.0 not sure how the speed of it changed since that)
