commit 489a3834d27c9add73d15e4c027856f6a39276a4 Author: Lynne <[email protected]> AuthorDate: Tue May 12 22:26:11 2026 +0900 Commit: Lynne <[email protected]> CommitDate: Tue May 19 03:22:29 2026 +0900 swscale/vulkan: implement SWS_OP_PACK/SWS_OP_UNPACK The issue is that while Vulkan already does the decomposition for us, swscale assumes that the pixels will be in bitstream order, rather than in their decomposed form. This is valid for all packed formats for which these instructions are issued (XV30 and X2RGB10). This allows us to support the formats in Vulkan.
