How to disable "related videos" from an embedded youtube playlist

If I look through the YouTube Embedded Players and Player Parameters docs, there is no such thing to order the more videos section if you pause the video.

The two parameters I suggest to get near as possible to your goal is:

You can add:

• listType=playlist
• rel=0 to turn off related videos from the more videos section.

Note: The behaviour of rel=0 will be removed after September 25, 2019.

Conclusion:

It seems like what you want to achieve is not possible. With the default embed iframe of YouTube.

You might want to consider to look to other players with playlist options. Something like JW Player note that you need a licence for this player, JW Player playlist docs. I did some reading on JW Player as well, they currently don't support YouTube videos.

But maybe there are other players that have the same functionally for free.

Update for 2021

Youtube now seems to have a loop function that can be used to git rid of “related videos”. What it does basically is that when your video ends, it restarts again instead of showing (un)related videos. It worked perfectly in my case. Here is the code:

https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1

Please make sure to replace both VIDEO_ID in the code with your video ID. N̲o̲ N̲e̲e̲d̲ for creating a playlist

Example of full iframe code with player controls being enabled

<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1" title="YouTube video player" rel="0" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Example of full iframe code with player controls being disabled

<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1&controls=0" title="YouTube video player" rel="0" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

If you add &rel=0 at the end of playlist link - in related videos will be showed only videos from your playlist. Example:

<iframe class="rep" src="https://www.youtube.com/embed/videoseries?list=PLUl4u3cNGP63gFHB6xb-kVBiQHYe_4hSi&rel=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

If you remove &rel=0 from the link, it show random videos from youtube
