Subject: [FFmpeg-devel] [PATCH 3/4] avfilter/vf_lut3d: fix leak if allocate_3dlut failed
Date: Fri, 27 Jun 2025 22:09:17 +0800
Message-ID: <20250627140918.2832152-4-502024330056@smail.nju.edu.cn> (raw)
In-Reply-To: <20250627140918.2832152-1-502024330056@smail.nju.edu.cn>
In parse_cinespace(), memory allocated in in_prelut[] and out_prelut[]
would leak if allocate_3dlut() failed. Replace return ret with goto end
to free memory before return error code.
