Subject: [FFmpeg-devel] [PATCH] qsvenc: avoid dereferencing the null pointer
Date: Thu, 24 Feb 2022 10:27:40 +0800
Message-ID: <20220224022740.58216-2-tong1.wu@intel.com> (raw)
In-Reply-To: <20220224022740.58216-1-tong1.wu@intel.com>
The variable AVFrame *frame could be a null pointer, now add a null
pointer check to avoid dereferencing the null pointer.
