Wow, faststream works great for normal web players. Doesn't seem to work on any youtube videos when using the ff extension in the store though. Gets stuck loading forever.
Kind of unrelated, but how difficult do you think it would be to hack support for glsl shaders in a browser? I tried to look into it once, but got a bit lost in the media source side of things. My idea was to try to add glsl shaders as post processing to video streams like in mpv but without having to jump through all the hurdles of passing data to mpv.
Yeah all the pieces are already there, but I was trying to make something like a player replacer that would let the user load arbitrary glsl shaders to use. The idea being to provide usable upscaling or filters for weak connections or old videos, correct shaky videos, etc. in real time.
I just found this for fsr [0] which might work for the upscaling use case.
Edit: fixed, works well in every test case
