I have the following code which detect the video id from a string. It actually catch more cases that I need, and I would like to make it more simply and return the id only for string in this formats:

https://www.youtube.com/watch?v=85PMSYAguZ8
https://youtu.be/85PMSYAguZ8

Code:

_getVideoIdFromUrl: function (value) {
var regEx = /^(?:https?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v=|watch\?.+&v=))((\w|-){11})(?:\S+)?$/;
var matches = value.match(regEx);
if (matches) {
    return matches[1];
}
return false;

I would need help to change the regEx accordingly, any ideas?

Currently it detects:
