Again, for unregistered SEI you don't have a choice. Some encoders put tons
of private data in there. Some of the stuff is human readable, some of it
isn't.

The OP wants to test an implementation they have and they should do it
using the API, not using ffprobe to test their third party implementation
of something.

"Parsed by FFmpeg" sounds like you are proposing to extend the FFmpeg

As the OP says, this SEI data is from "MISB ST 0604" which is something
that could be implemented in FFmpeg and parsed properly like all the other
side data instead of just writing random binary data to the terminal.

I don't understand why any of this is hard to comprehend.
