commit 8f567d5cab578b085ff3ca79c9a1dd3fde433941 Author: David Christle <[email protected]> AuthorDate: Fri Feb 6 01:17:38 2026 -0500 Commit: Martin Storsjö <[email protected]> CommitDate: Mon Mar 2 13:14:07 2026 +0000 tests/checkasm/sw_yuv2rgb: test multi-row conversion with padded strides Increase test height from 2 to 4 rows and add 32 bytes of source stride padding. This exercises chroma row sharing across multiple luma row pairs in YUV420P and the stride increment arithmetic in SIMD implementations, both of which were previously untested.
