Subject: Re: [FFmpeg-devel] Late SEI is not implemented (providing a sample)
Date: Sun, 15 Jan 2023 15:42:17 +0000
Message-ID: <0F5CDFE7-8F38-44B2-9C28-B23305B0F2C4@kodi.tv> (raw)
Answering my own question here in case someone else stumbles into this, it turns out those streams were completely broken:
- The CC data SEI NAL units were defined after the primary coded picture which violates the H264 standard
- The user data part of SEI was lacking the marker_bits (0xFF) at the end
Both issues were fixed upstream by the Dash industry forum and the public samples regenerated after the report, they work correctly now in ffmpeg.
