Info about the car (i.e. year, trim, motor) would help. I’m assuming you have a 92 GSR by your username. Sounds like a vacuum leak. Also, since it happens on cold start, it could also be something related to your Fast Idle Thermo Valve (FITV). Check the stickied thread that talks about rough idle, it should point you in the right direction.
I thought there was a stickied thread, but I guess I was wrong. Either way, do a search for low idle or rough idle and you should be able to come across some good reads. I know I’ve read countless threads about idle issues pointing in the same direction.
Also, I can’t check out your video from this PC I’m using. Therefore, I’m just going by what you typed up.
Seen the video and also believe its the FITV that might need to be cleaned/adjusted. You mentioned that coming to a stop the car sometimes dies, i had the same issue a while back and it was a vacuum leak coming from the brake booster. This leak didn’t cause a hight idle like most but rather a very low idle (weird). There is a ton of info about idle issues of Hondas online and especially here, just search.
I’m currently having an idle issue and assumed it was the booster from some initial tests I had done. However, the other day I tried to replicate while the idle was acting up and dropping low, but it didn’t help. Have a pair of pliers handy and next time the issue is happening while braking, pull the hose off that goes from the intake manifold to the check valve on the booster. Use something to plug the end that is still connected to the intake manifold. If your idle evens out and is no longer an issue, the booster is probably the problem, but make sure it’s not the check valve also. There are also a couple tests explained in the Helms manual, but I can’t think of them at the moment and don’t have access to the manual.
