问题
I am trying to embed a YouTube video with loop mode on, and to do so I have to set the playlist parameter otherwise it won't work:

The problem is when I do so i get a playlist with 2 videos on it, the same video appearing twice, which produces a very bad visual effect since i want one video to loop endlessly.
Any suggestions on how to do so? Thanks
Here's my code:
<iframe width="600" height="338"
src="https://www.youtube.com/embed/VIDEO_ID/?playlist=VIDEO_ID&autoplay=1&loop=1&rel=0&showinfo=0&color=white"
frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

I don't think the following information is actually documented somewhere, but I want share the discovery I made by making some tests in the URL for trying solve your "problem".
Saying this, you can remove your "problem" - (which is: displaying the same video twice) - by modifying the URL as follows:
https://www.youtube.com/embed/VIDEO_ID_1/?playlist=VIDEO_ID_2&autoplay=1&loop=1&rel=0&showinfo=0&color=white
Explanation:
VIDEO_ID_1: Corresponds to thevideoIdintended to play continuously - (in loop).VIDEO_ID_2: Corresponds to thevideoIdusted in theVIDEO_ID_1, BUT with the last letter changed. The idea is set avideoIdthat does not exist.
So, with the previous explanation, you can use the following video as an example:
Video: Stack Overflow is 10!
videoId:
QwS1r1mc888
The modified URL shows the following:
https://www.youtube.com/embed/QwS1r1mc888?enablejsapi=1&loop=1&playlist=QwS1r1mc880&autoplay=1&rel=0&showinfo=0&color=white
N.B that the videoId
QwS1r1mc880does not exist (yet) - you could also replace this value for15874598752- which will never be a YouTubevideoId(as far as I know).
Side note: I really hope this discovery won't be removed.
