[PATCH 0/6] MR9913: Draft: winedmo: Allow building against multiple and specific FFmpeg versions.
by Rémi Bernon Jan. 22, 2026

Jan. 22, 2026

This would achieve ABI compatibility with arbitrary FFmpeg versions, without having to redefine / fixup FFmpeg structures manually. Downstream Wine distributions may be interested in having an embedded but crippled FFmpeg shipped with them, avoiding issues related to FFmpeg distribution, while still being able to dynamically load the system, or externally provided, more capable FFmpeg version. The distributions would only need to build every supported winedmo versions, targeting the corresponding FFmpeg ABI, to later dynamically load them. The non-versioned winedmo would load the distribution embedded FFmpeg for instance, while the versioned modules would target a matching system library. This also introduces an unified interface with winegstreamer, allowing us to get rid of the duplicated media source code. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9913

[PATCH v2 0/1] MR9897: mf/session: Discard end of presentation on IMFMediaSession_Stop.
by Rémi Bernon Jan. 22, 2026

Jan. 22, 2026

Some games calls IMFMediaSession_Stop while the presentation is ending, expects that command to quickly execute, interrupting the presentation end and emitting a MESessionStopped event instead of the MESessionEnded. Delaying the Stop command and emitting the MESessionEnded event breaks the game assumptions and it crashes, or waits for the MESessionStopped event forever. This is a redone of https://gitlab.winehq.org/wine/wine/-/merge_requests/1710, which still appears to be necessary for Disintegration. Haven't tested Life is Strange again, but I suspect it's probably some quirks of some Unreal Engine version. -- v2: mf/session: Discard end of presentation on IMFMediaSession_Stop. https://gitlab.winehq.org/wine/wine/-/merge_requests/9897

[PATCH v17 0/4] MR9265: crt: Run MSVC constructors and destructors
by Yuxuan Shui (＠yshui) Jan. 22, 2026

Jan. 22, 2026

There are several motivations to enable ctor/dtor support: 1. ASan. This is not just about my wine-asan work, this is important for @bernhardu's PE asan work as well. The compiler generates ctors that poisons memory around global variables so misuses of them can be caught. This is the same both of our implementations of ASan. 2. Building third-party codebases against wine's CRT. This is not necessary for mingw-gcc or llvm-mingw, but the MSVC frontend of clang is another option for cross-compiling to Windows. However right now that requires Windows SDK. Bringing wine CRT to the point of being functional enough will give us another option. Could be useful for things like Proton. 3. (Controversial) Many dlls perform init/deinit tasks in `DllMain`. Some of them might benefit from a conversion to ctor/dtor. Since nothing in wine uses ctor/dtor right now, this change shouldn't have any impact by itself. -- v17: crt: Run MSVC constructors and destructors. https://gitlab.winehq.org/wine/wine/-/merge_requests/9265

Hi, Does this series exactly fix the issue and make those games playable? AFAIU, it is AntiCheatExpert requires these functions, and sometimes just implementing a couple of functions is far from making the game playable; what is worse, maybe some other game will become unplayable because the exposing of these functions guides them to another code path (e.g. it goes further in the anti-cheat detection) that has issues on Wine. btw, Arknights: Endfield, which ships AntiCheatExpert, depends on KeAcquireGuardedMutex() too. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2044#note_127675

[PATCH 0/1] MR9486: windowscodecs: correct GIF LZW compression initialization
by Jiajin Cui (＠jin-king1) Jan. 22, 2026

Jan. 22, 2026

The GIF LZW compression algorithm was incorrectly initializing the code size to 8 bits regardless of the actual color depth. This caused issues with images that have fewer colors requiring smaller initial code sizes. The fix calculates the proper initial code size based on the actual number of colors in the image, using the formula: minimum code size = max(2, ceil(log2(color_count))). This ensures proper compression for images with small color palettes and maintains compatibility with GIF decoders that expect correct LZW initialization parameters.
