This tip covers how to create Youtube embed links for use in full screen or iframes.
(related pages Youtube URL parameters and Youtube live channels)
Embed links provide a clean and officially supported method to view a Youtube video without the surrounding text or thumbnail links to other videos, making ideal to embed in your own web page or view as a full screen. Suppose a video has the following link:
https://www.youtube.com/watch?v=ABCDEFGHIJK
The embed link is then:
https://www.youtube.com/embed/ABCDEFGHIJK
Note: The embed link may not play if disabled by the video owner
A Youtube livestream permanent URL is of the form:
https://youtube.com/channel/CHANNEL_ID/live
The embed link is then:
https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID
The CHANNEL_ID is the 24 character Youtube User ID available in the Advanced Settings in Youtube. It will also be contained in the URL of the channel owners page.
eg. https://www.youtube.com/channel/UCLA3Uc4amh-v5eIS6M_r2ow
To autoplay, add &autoplay=1 to end of link. Other parameters can also be added.
