ffmpeg | branch: master | Michael Niedermayer <michael at niedermayer.cc> | Tue Feb 20 03:32:38 2024 +0100| [e9cc9e492f987ce23ce8c514258a17952dd20401] | committer: Michael Niedermayer

libswscale/utils: Fix bayer to yuvj

Fixes: out of array access.

Earlier code assumes that a unscaled bayer to yuvj420 converter exists
but the later code then skips yuvj420
