Just put “?autoplay=1” in the url the video will autoload.
So your url would be:
https://youtube.com/watch?v=JW5meKfy3fY%3Fautoplay%3D1
In case you wanna disable autoplay, just make 1 to 0 as
?autoplay=0
Actually, you will have to use the “?” instead of “&” for your first parameter only. If you use more than one parameter, you will then have to add “&” to the chain.
For instance, if you want to add autoplay and closed captioning, you will have to add this portion to your embedded video URL: ?autoplay=1&cc_load_policy=1.
It would look like this:
