Subject: [FFmpeg-devel] [PATCH 3/3] avcodec/h264dec: Constify slices' pointer to the parent context
Date: Thu, 24 Mar 2022 21:21:51 +0100
Message-ID: <AS1PR01MB9564BB00446ED41264E643A48F199@AS1PR01MB9564.eurprd01.prod.exchangelabs.com> (raw)
In-Reply-To: <AS1PR01MB95645B7A1124DEDE589F0EC48F199@AS1PR01MB9564.eurprd01.prod.exchangelabs.com>
Modifying the main context by a slice thread is racy;
so constify the pointer to it in H264SliceContext.
The code itself was already compatible with this change.
