Interesting, I take it you don't remember the source? I might want to look into that.
@HoukaiAmplifier99 I don't remember my source, and I can't find anything searching around. I either made it up or it was an unsubstantiated reddit comment that stuck in my brain :)
For real instances of this problem though, look at Glorious Eggroll if you haven't already. Contains a number of additional video codecs Valve can't yet support directly.
Oh yeah Proton-GE is definitely my go-to usually, has fixed some stuff before, but there are still cases where it doesn't help. Idk what it does under the hood though.
Why would valve need to support the codecs? I don't think Microsoft goes out of its way to support proprietary codecs in windows for a games to be able to decode them. What makes that necessary when running the game in proton?
@Lojcs Microsoft does exactly that. They licence a number of proprietary codecs for inclusion in Windows for the convenience of users.
Running under Wine, some alternative decoders can be used, but many proprietary codecs don't have freely-available decoders available. Under Proton, many free decoders can be used like Wine, but some prohibit commercial use or otherwise can't be implemented in Proton via Valve. GE-Proton manages the best of both worlds.
Considering that windows doesn't even have a free h.265 software decoder to use in its video app, it's hard to believe that it might support codecs obscure enough to not have open source decoders even in GE proton. Thanks for the reply tho
