The source is using a youtube URL for the streaming video and I use either
youtube-dl or ffmpeg directly to get it in my scripts.

Is the fact that the times are so exact indication of recoding by Youtube, or is
the source like that?
I really have no idea how Youtube video streaming works, I just use YouTube if
that is the source...
And I have never published any video on Youtube so I don't know the process.
