Yeah, I just reported the bug there. There was an older one that could be the same:

https://bugs.winehq.org/show_bug.cgi?id=50277

Running the game with stand alone Proton 9 seems to work fine here. At least the intro plays without problems.

I run the Proton binary directly without using Steam or the runtime so it uses my system libraries and local GStreamer/ffmpeg to decode the videos instead of using the transcoded versions.

The vast majority of the mfplat (and quartz etc.) happens in upstream Wine, but Proton pulls in a lot of cherry picked patches, stuff from staging and a bucket load of hacks specific to games so trying to figure out exactly what makes the videos work in this case might be hard.

Unless you have a good reason to use vanilla Wine you're almost always better of with Proton or -GE for games, even non-Steam ones.

GE stopped making releases altogether and decided to switch to some other format? And most developers don't recommend using Proton for non Steam games.

How can I narrow down which patches Proton applies to mfplat? I can try reproducing those. I prefer to stick to upstream Wine with only minimal patches when necessary. I tried staging btw, it didn't help in this case.

Comparing these:

* https://github.com/ValveSoftware/wine/commits/f80ddae9e217f2bad68455891371fa0f524451e7/dlls/mfplat
* https://gitlab.winehq.org/wine/wine/-/commits/master/dlls/mfplat?ref_type=undefined

Looks like proton is behind on some commits but also has non upstreamed ones.

I guess I'll wait until Wine pulls some of that upstream.

No idea, I don't think I've ever used -GE.

And there's a bunch of other mf dlls. mfplay, mfmediaengine etc. Plus the winegstreamer dll.

Sadly I don't think there's any easy way to figure out to narrow down the changes introduced to Proton.

I'll try to dig into all of them and compile a list of differences when I have time.

I hope Wine developers are upstreaming what's possible.

This is interesting: https://gitlab.winehq.org/wine/wine/-/merge_requests/5340#note_75745

Looks like Wine developers are considering switching away from using gstreamer. I wonder what they'll use, may be ffmpeg? Hopefully that will result in this whole situation improving.

yeah this is a really big trouble, well this situation need much time for see improvements and if them stay thinking seriously leave gstreamer

Yeah, that would probably be a while before they replace it.
