decode vorbis_comment section from webm video file

From Unreal Tournament .webm recording library.

I came across the following lines of code:


 // Tell them UT wrote this
vorbis_comment vc;
vorbis_comment_init(&vc);
vorbis_comment_add_tag(&vc, "ENCODER", "UnrealTournament");

[TABLE=“class: highlight tab-size js-file-line-container”]

and in the video file, I saw that

was added into the header.

I was trying to find a way to decode the header and retrieve that line but couldn’t find any solution.
