I have to display some private Youtube videos in my blog. I cannot embed them directly. What should I use to do this.
Yes you can embed private and unlisted files on your website. If private, Youtube will ask for a login (if there is none) and the credentials will give access to watch the content or not, based on you are a manager/admin of the channel or have an invitation (invite emails from dashboard).
If unlisted it will show!
The video must be embeddable!
