That's obviously this video he's talking about (second video after searching "mark knopfler french" on YouTube):
I remember being absolutely obsessed over this video, I thought it's a kind of magic. But today I only realize that's just a musician playing some random stuff on guitar. Yes, the musician happens to be the one with one of the most recognizable sounds in the world, but the actual jam doesn't make sense, just some random bits and pieces of music. I wouldn't bother transcribing it. This video is perfect for being an inspiration for someone, who would be obsessed over this sound like me.
