[PATCH v7 0/8] MR8812: winegstreamer: Support 2D sample buffer.
by Conor McCarthy (＠cmccarthy) 02 Dec '25

02 Dec '25

Performance issues can occur when a video output sample has a 2D buffer, because winegstreamer currently outputs only to a linear buffer, which must then be copied into the 2D buffer. Worse, a linear lock of the 2D buffer requires the current contents to be copied to a linear buffer, even when we intend to overwrite it, because MF linear buffers do not support write-only locking. -- v7: winegstreamer: Support 2D sample buffer. mf/tests: Test color convert 2D buffers. https://gitlab.winehq.org/wine/wine/-/merge_requests/8812

[PATCH v7 0/4] MR8505: mfsrcsnk: Implement thinning.
by Charlotte Pabst (＠CharlottePabst) 02 Dec '25

02 Dec '25

Follow-up to !8184. This also adds a bunch of helpers for writing media source tests (without involving the mf session) in mfsrcsnk, these could be helpful for more tests of this kind in the future. I'm somewhat unsure as to why we haven't done tests for source behavior so far: while those are plugins, applications rely on a bunch of things in the builtin sources that microsoft provides. Since this affects both mfsrcsnk and winegstreamer sources, tests should be run both with `HKCU\\Software\\Wine\\MediaFoundation\\DisableGstByteStreamHandler` enabled and disabled. Due to this I figured it'd make sense to implement everything first and then remove the test todo_wine's and the statements rejecting the thin parameter in a single commit ("Allow thinning"). Perhaps this could be solved more nicely by setting the registry key in the tests themselves? I'm unsure if that is something we do in tests, generally. `MEStreamThinMode` events need to be emitted between the last sample using the outdated thinning parameter and the first sample using the updated thinning parameter. The winegstreamer implementation for this turned out a bit complex, if there is a simpler way to do this please let me know. Regarding winegstreamer, note that buffers need to be intercepted before the decoder because decoders often discard `GST_BUFFER_FLAG_DELTA_UNIT` flags (which is already annoying in itself - it causes all samples to be marked as `MFSampleExtension_CleanPoint`, this should potentially be worked around in the future). But even besides that, intercepting before the decoder is the "proper" implementation, since the point of thinning is increasing decoding speed by skipping delta frames, tho there are some games that rely on the semantics as well. -- v7: mfsrcsnk: Implement thinning. https://gitlab.winehq.org/wine/wine/-/merge_requests/8505

[PATCH v2 0/3] MR9454: Revert "winmm: Use AUTOCONVERTPCM when initializing the audio client."
by Giovanni Mascellani (＠giomasce) 02 Dec '25

02 Dec '25

This reverts commit 21fb3555ed1f26e46d4c82cb2ec8fc29f730a0e9, which inadvertently removed support for converting audio formats not directly supported by mmdevapi. I'll work on a better solution over the next few days. -- v2: Revert "winmm: Use AUTOCONVERTPCM when initializing the audio client." https://gitlab.winehq.org/wine/wine/-/merge_requests/9454

[PATCH 0/1] MR9655: winevulkan: Update to VK spec version 1.4.335.
by Georg Lehmann (＠DadSchoorse) 02 Dec '25

02 Dec '25

We should support VK_EXT_present_timing at some point, but it's not trivial to handle and I won't have time for it before the code freeze (nor a linux driver to test). For now, at least update the spec to ship the VK_EXT_ray_tracing_invocation_reorder fix. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9655

[PATCH v3 0/2] MR9639: Fix the integration of PowerPoint add-in in MS Office 2016
by Ivan Lyugaev (＠valy) 02 Dec '25

02 Dec '25

Encountered an issue with PowerPoint add-in integration. Reviewing the logs revealed the problem was due to the lack of CLSID lookup via the CurVer section and incorrect handling of the PARAMFLAG_NONE flag. A test was conducted in Windows to verify the handling of PARAMFLAG_NONE, PARAMFLAG_FIN, and PARAMFLAG_FOUT. Test class: ``` interface ITest : IDispatch { [id(1)] HRESULT TestMethod(BSTR* value); [id(2)] HRESULT TestMethodOut([out] BSTR* retVal); [id(3)] HRESULT TestMethodIn([in] BSTR* inVal); }; ``` Results in Windows: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) Invoke returned: 0x00000000 ``` Results in Wine: ``` --------TestMethod-------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethod] (null) Invoke returned: 0x00000000 -------TestMethodIn------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodIn] Hello from VT_BSTR Invoke returned: 0x00000000 -------TestMethodOut------- Variant type: 0x0008 (VT_BSTR) [CTest::TestMethodOut] (null) ``` Therefore, parameters with the PARAMFLAG_NONE flag are implied to be input parameters in Windows and are handled accordingly as PARAMFLAG_FIN. Added tests for the implemented changes. In the last two tests (their code is provided below), the CLSID is nullified in the guid_from_string function, which is why this test is left with a todo_wine tag. ``` clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.3", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); clsid = CLSID_StdFont; hr = CLSIDFromString(L"MyApp.DocumentTest.5", &clsid); todo_wine ok(IsEqualCLSID(&clsid, &CLSID_StdFont), "Unexpected clsid %s.\n", wine_dbgstr_guid(&clsid)); ``` -- v3: combase: Implement CLSID lookup with CurVer fallback oleaut32: Fix parameter value loss in ITypeInfo_Invoke for byref parameters https://gitlab.winehq.org/wine/wine/-/merge_requests/9639
