Okay. I was following the above links to writing my own metadata file.

I used "barectf config.yaml -m ctf" command. It helpled me generating the
metadata file. I looked at some other metadata file but they are binary
packetized. The one I generated using barectf is not binary packetized.

Are these file different?
Will both work the same way?
