Steam / proton game that runs .mp4 randomly freezes

Hi,

I found an issue that I have not been able to fix related to steam and mp4 playing in games.

I’ve been playing a bit of Marvel Rivals. Using proton-cachyos, mostly with NTsync version, but I dont think it’s related to it.

How I found out that the freezes were related to the .mp4 playing in the game?

Before, when modding was possible, I did disabled the intros and videos playing in the game, the game has a bunch of them, all of them being in mp4. By replacing it with a 0 byte video, it instantly bypassed them.

With that, the random freezes also stopped. But now, they completely disabled modding in all ways. So, the intros and freezings are back.

I wonder if it’s related to anything from proton / sdl or whatever causing freezes when playing videos inside games?

Anyone have any idea?

Don’t use the NTsync version, it’s unsupported. Does this happen with Proton Experimental and/or Proton-GE too?

I’ve been using the NTSync version with all games, it only happens in this specific one. So, the problem are probably unrelated to it. It’s very stable imo.

I didnt use any other. As I prefer the smoothness that comes with it. NTsync in latest Proton-CachyOS, Wine-CachyOS - #10 by random-user
