How to modify a regular expression to parse a parameter from a YouTube URL [closed]

Answer 1

Capture YouTube video ID (and time seek parameter t if exists)

RegExp:

^(?:https?\:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v\=))([\w-]{10,12})(?:[\&\?\#].*?)*?(?:[\&\?\#]t=([\dhm]+s))?$

PS: you'll note I improved your original RegEx to validate the YouTube link safely
