Subject: [FFmpeg-devel] [PATCH] avcodec/nvenc: fix NULL pointer dereference
Date: Wed, 1 Mar 2023 02:43:43 +0800
Message-ID: <tencent_0126DCE7F26A8E13075C744BAEA61E508F06@qq.com> (raw)
From: Zhao Zhili <zhilizhao@tencent.com>
This can happen if encoder init failed before setup the queue, then
reorder_queue_flush() is called by close().
Fix ticket #10221
