I couldn't get teh volume to work so I haven't got the full flavour but this is what I would do.
He doesn't looked very relaxed. I'd work out what WILL make him relaxed - personally I would half-wrap him then I'd sit on the rocking chair next to the cot and rock him for a up to a few minutes and say nice soothing things to him, like "what a nice morning we 've had, sleepy time now, oh, it's time for a nice sleep." I think hearing soothing things is very important to babies.
Then when he looks relaxed and his eyes are starting to close, I'd get up and continue rocking a bit then transfer to cot and carry on saying "sleepy time now".
If he's quietish, I'd then leave and ONLY go back if he's crying (rather than having a bit of a grizzle).
I think the key is to get them relaxed but let them go that last mile to putting themselves to sleep on their own. But you have to be persistent - it took four days of doing that at EVERY sleep for my DD to get it - doesn't sound long but that's about 30 sleeps in total because she was only a couple of months old.
