Over this summer, I played with HDMI grabbers on #linux , this is a summary of the experiments, what works well and what not: https://blog.fluxcoil.net/posts/2020/11/linux-hdmi-grabber-1/
Great idea! How to upscale older applications, for example old games, on #linux :
So I gave in and got a Playstation 4.
Would love to run #linux on that hardware I just bought. The consoles are no longer subsidized.. #sony does not make that possible. Apparently they fear it would make it easier to run copies of games? Shame on you.
You are apparently not ashamed of using #opensource code, judging from the licenses used.
Oh, and I can not use my Sony WH-1000XM2 heaset via bluetooth, one of your own products..
