Subject: [FFmpeg-devel] [PATCH 3/3] libswscale/utils: Fix bayer to yuvj
Date: Tue, 20 Feb 2024 03:49:22 +0100
Message-ID: <20240220024922.22779-3-michael@niedermayer.cc> (raw)
In-Reply-To: <20240220024922.22779-1-michael@niedermayer.cc>
Fixes: out of array access.
Earlier code assumes that a unscaled bayer to yuvj420 converter exists
but the later code then skips yuvj420
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
