At some point (and without my interaction), the YouTube video background in my slider stopped playing, and I can’t get it working no matter what I do. On another slider, the video background (different video, implemented the exact same way) seems to work fine.
I’ve checked in multiple browsers on multiple machines, and I’ve tried making a brand new slider and replacing the old one, but it seems that the new slider I create won’t show the YouTube video background either. I’ve even downloaded the video from YouTube, edited it down and reuploaded it on another channel, to no effect. So I’ve figured out that it’s not the browser, it’s not the implementation, it’s not the particular slider and it’s not the video I’m linking or the account it’s on.
Thanks in advance!
