From 8940a6153ff60f9649d5bbde021df98bae68d543 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Tue, 4 Mar 2025 18:07:23 +0100 Subject: [PATCH] avcodec/mjpegenc: Constify parent ctx in encode_block() Said parent is shared between all slice contexts and encode_block() can be run concurrently by slice threads, so the parent context must not be (and is not) modified. So constify the pointers.
