Do you happen to have an RFC or other reference docs about this NAL type?

Hi!

Yes FRC3984 describes the SEI types, section 4.1, here the link:

https://www.ietf.org/rfc/rfc3984.txt

The main referencia IMHO is our Axis repository for "Signed Video Framework"

https://github.com/AxisCommunications/signed-video-framework/blob/master/README.md

BR, José
