commit 467f8d8415e8818f8ef60aa099f5d5201b0c6dc6 Author: Andreas Rheinhardt <[email protected]> AuthorDate: Mon Mar 2 21:38:29 2026 +0100 Commit: Andreas Rheinhardt <[email protected]> CommitDate: Fri Mar 6 20:02:42 2026 +0100 avcodec/x86/vvc/alf: Improve offsetting pointers It can be combined with an earlier lea for the loop processing 16 pixels at a time; it is unnecessary for the tail, because the new values will be overwritten immediately afterwards anyway.
