[PATCH v7 0/5] MR9572: opengl32: Implement GL_EXT_memory_object_win32 for base handle types.
by Derek Lesho (＠dlesho) Jan. 20, 2026

Jan. 20, 2026

Not sure about the extension replacement mechanism. Also, should tests be failing when extensions aren't supported? -- v7: opengl32: Expose GL_EXT_memory_object_win32. win32u/opengl: Implement glImportMemoryWin32(Handle/Name)EXT for opaque handle types. opengl32, win32u: Move gl_error to wgl_context. https://gitlab.winehq.org/wine/wine/-/merge_requests/9572

[PATCH 0/1] MR9937: winegstreamer: Protect wg_transform drain and flush by mutex.
by Charlotte Pabst (＠CharlottePabst) Jan. 20, 2026

Jan. 20, 2026

When flushing and draining at the same time from different threads without synchronization, one of them may fail and in the worst case, both fail, and the pipeline gets permanently stuck in EOS state. I'm dealing with a game that drains the Video Decoder MFT immediately after sending a stop command to the media session. In some cases, after the session is started again, the decoder does not output any samples anymore. The simple instance of this bug (with only one of them failing) stems from either drain-related events being pushed while the src pad is flushing, or flush-related events being pushed while the src pad is EOS. This does not cause any problems in the application. In the more complex case, the flush-stop event is processed by some pads (src in particular) but not yet the entire pipeline when a context switch happens, meaning that when the draining thread pushes its EOS event, it fails at a later pad (complete_drain then also fails), but is still stored as sticky in the src pad. After flush-stop finishes propagating, the stored EOS event then also propagates, leaving all pads in EOS state. This is the main problem I'm concerned about. I'm attaching `GST_DEBUG="4,WINE:9,GST_PADS:6,GST_EVENT:6"` logs for the EOS bug, as well as a test program. Note that the EOS case is comparatively rare. I'm unsure if this is the best fix for this issue, feel free to suggest something different.

Re: [PATCH v2 0/5] MR9588: dsound: Introduce a cubic spline interpolation resampler.
by Matteo Bruni (＠Mystral) Jan. 20, 2026

Jan. 20, 2026

> Here are my changes: !9928 I left a large comment over there which I'm not replicating here :sweat_smile: Good job though! > I also tried to add AVX+FMA3 versions of the resampling functions, but I'm getting diminishing returns. The bottleneck might be the indirect calls to `get` and `put` or the index calculation code in the outer loop. I haven't tried myself but I suspect this is where the computational complexity of the current filter comes back to bite us. As much as you can make the arithmetic and data accesses faster, it's always going to be ~60 multiplications and additions fetching data from 2 "large" arrays per sample for a FIR / sinc filter vs one order of magnitude fewer arithmetic operations, accessing a single large input data array for a cubic one. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9588#note_127395

[PATCH 0/28] MR9928: Draft: dsound: Speed up resampling.
by Anton Baskanov (＠baskanov) Jan. 20, 2026

Jan. 20, 2026

This implements a number of optimizations, in particular: - Swapping around the resampling loops in case of downsampling, allowing the FIR step to stay fixed regardless of the resampling ratio. - Rearranging the FIR array elements to make the access sequential. - Adding SSE versions of the resampling functions. Together, these amount to more than a 5x reduction of `cp_fields_resample` execution time. The quality of the resampling should be the same, or even improve slightly, due to a more precise `rem` calculation and removal of the FIR step rounding, although I haven't yet conducted any measurements. -- This merge request has too many patches to be relayed via email.
