Before doing these things you should check the maximum power the diode can withstand, besides all the power is dissipated on the single diode so it will fail sooner.

Actually, it's not. The man put in the appropriate resistor to drop the amperage to an appropriate level for this circuit. It's only dangerous if you don't know what you're doing.
He puts a resistor with a high resistance in series with the phase, making this not dangerous. It's just as safe as either a bare 12 volt supply or less, like your battery on your car, because the voltage drop across the large resistor makes the voltage drop. Now, since these are small LEDs, I would assume they are between one to three volt LEDs, making that the potential between you and the ground. So no, this is not dangerous.
ofcourse its dangerous. Anything you put in mains is not adviced. Yeah the circuit maybe safe (if the components can survive the occuring watts and dont burn). But the way its shown here its easy to short something out in the process making it incredibly unsafe.

Keep in mind that this led strip isn't intended to work like that. It's not insulated, and depending on how you plug it in the mains, all you can have between you and the line could be just a diode. So touching the led strip as the thing is plugged can shock you. Also, this isn't really a very efficient way of powering a led strips. Most of the power is going to be wasted on the resistor. It's going to be heating up with around 1.5W due to this being powered by a half wave rectified dc. The led strip appears to be low voltage as there are 12 leds and if it was a series one this would exceed the 25V rating of the capacitor. So that's even less efficient. This circuit would produce lots more light if it was powering a series string of leds.
depends what you want as output. full bridge rectifier is useful to use positive parts AND negative parts of the pulse. he's using half the pulse, hence half the volts main power offers. usually power supply just take both pulse (to avoid bad balance in power consumption) then reduce them with a transformer, offering galvanic insulation. he don't, meaning anyone touching a metal part is potentially exposed to full main voltage.
Dont do that! 1. It's hot by power loss at R limit current. 2. Non isolated AC source. 3. It's aluminium pcb. Leaking current cause quite low impedance to ground
remember that approximately Ir=(230*radq(2)-2)/15000=22mA flows on the resistance inside the plug So the total power on it is: Ptot=0.22^2*15000=7W The resistor in the video allows at most 1/4W... about 10x less.
