commit fd77f00a8ff8f0558fef1bf7670c34b009414f2b Author: Andreas Rheinhardt <[email protected]> AuthorDate: Wed Apr 8 09:29:33 2026 +0200 Commit: Andreas Rheinhardt <[email protected]> CommitDate: Mon Apr 13 12:46:24 2026 +0200 avcodec/snow: Avoid always-true branch The input lines used in ff_snow_inner_add_yblock() must always be set (because their values are used).
