[PATCH v5 0/8] MR8812: winegstreamer: Support 2D sample buffer.
by Conor McCarthy (＠cmccarthy) Nov. 3, 2025

Nov. 3, 2025

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. -- v5: winegstreamer: Support 2D sample buffer. mf/tests: Test color convert 2D buffers. mf/tests: Test WMV decoder 2D buffers. mf/tests: Test H.264 decoder 2D buffers. mf/tests: Test sample copier 2D buffers. mfplat/tests: Test NV12 negative stride in MFCreateMediaBufferFromMediaType(). mf/tests: Remove todo for an H.264 decoder test. mf/tests: Stop checking samples at the end of the expected array. https://gitlab.winehq.org/wine/wine/-/merge_requests/8812

[PATCH v2 0/1] MR9339: winhttp/tests: Avoid buffer-overflow in WinHttpCreateUrl_test (ASan).
by Bernhard Übelacker Nov. 3, 2025

Nov. 3, 2025

The test sets in fill_url_components the dwPasswordLength to 8, therefore the memcpy copies 8 wide characters. But before this patch variable empty allocates just one wide character.
