And why is NAL 40 invalid? Last time I checked it is https://github.com/FFmpeg/FFmpeg/blob/870bfe16a12bf09dca3a4ae27ef6f81a2de80c40/libavcodec/hevc.h#L69
HEVC_NAL_SEI_SUFFIX

And it is supported right here: https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200107050355.17503-7-lance.lmwang@gmail.com/

And otherwise it is just HDR metadata, like MDCV (56ed01169269451b7bb327c6bb250eec36ee3de2). So...

Hi, I am the original reporter of this issue. Just wondering if any of the maintainers have time to do the work required to properly support this slightly proprietary format? I believe there are an awfully large number of these IP cameras out there so it would be very much appreciated.

I think the web-based management UI that comes with the camera uses this:
https://github.com/strukturag/libde265.js

Hope someone can help.

Martianw
