Injecting metadata from file MISP

[Fran Raga]

Thanks for the quick response.
I definitely don't know how to do it, I don't know Gstreamer.

What I have is an original video, the MISB video created with a commercial
tool and the klv file extracted from that video.

What I want to generate is that video to not go through that commercial tool
I know that it has to be done in a flow, starting from a csv for example,
but I wanted to test if I got it in a first attempt.

thanks
