Subject: [FFmpeg-devel] [PATCH 0/3] swscale: refactor and optimize xyz12Torgb48
Date: Wed, 26 Nov 2025 15:26:10 +0000
Message-ID: <3szisuzpznn3w7sizkcf4zthigieqmqoqet4ghewysie53v5dp@7lzmeqgw4idb> (raw)
Hi,
This series prepares and optimizes the xyz12Torgb48 path in swscale.
Patch 1 refactors the XYZ/RGB state into a ColorXform struct and adds a
per-context xyz12Torgb48 hook with no functional changes.
Patch 2 adds checkasm coverage for the xyz12Torgb48le path.
Patch 3 introduces an AArch64 Neon implementation for the little-endian
xyz12 -> rgb48 conversion.
Comments welcome.
Arpad
