Got YouTube embeds on your website? Are you finding that previously suppressed related videos are now appearing?
Well, needless to say, Google have changed things and it’s causing some confusion.
tl;dr: the related videos parameter has changed and there’s now no way of removing related videos from the broadcast sorry.
Back in August (you were paying attention, weren’t you?) YouTube announced the following…
The behavior for the rel parameter is changing on or after September 25, 2018. The effect of the change is that you will not be able to disable related videos.
That’s pretty much it in a nutshell. Before this, you could simply add
&rel=0 to turn off the displayed of related videos at the end. Now this parameter (which can be set to 0 or 1) does the following…
0 – the player will show related videos that are from the same channel as the video that was just played
1 – the player will show related videos from any channel
And, no, there isn’t an alternative.
But that’s not all – they’ve now completely deprecated the
showinfo parameter, if you ever used that. This indicated whether the player should display information like the video title and uploader before the video starts playing. Now, the channel avatar and video title will always display before playback begins, when playback is paused, and when playback ends.
