Subject: [FFmpeg-devel] [PATCH] lavc/cbs_sei: Fix H.264/5 SEI unit ordering
Date: Mon, 24 Jan 2022 01:37:07 +0000
Message-ID: <abe4571410fa4ef3947119d5064dea3e@mx.toyon.corp> (raw)
Fixes regression from commit 8843607f495c95c1e67a3ce3d6f15dca6e252439
causing incorrect SEI unit ordering (e.g. after H264_NAL_IDR_SLICE when
prefix is specified).
