commit 01a897020e4d5d794cf16984796d4c8a2518bfaf Author: Andreas Rheinhardt <[email protected]> AuthorDate: Sat Feb 28 21:44:38 2026 +0100 Commit: Andreas Rheinhardt <[email protected]> CommitDate: Fri Mar 6 20:02:41 2026 +0100 avcodec/x86/vvc/alf: Use xmm registers where sufficient One always has eight samples when processing the luma remainder, so xmm registers are sufficient for everything.
