I’m the admin of a Xibo installation for one of my clients, and I’m hereby transmitting a question (the client speaks french). The Xibo installation works very well, by the way.
When he inserts the video in the webpage tab, the Youtube videoplayer is shown OK, but there’s an HTML 5 related error message. By the way, on the same client machine, the same video works on the Chrome web browser, but not with Xibo.
Could you confirm which player is in use and what is the CMS/player version please?
If it is Xibo for Windows, then it should render it the same as the IE11 does.
Regarding autoplay, if it is Windows, then you should be able to just add ?autoplay=1 to the end of the youtube URL, you should also use the /embed url, ie for example for the first URL you provided it should be: https://www.youtube.com/embed/HVywAcElAOI?autoplay=1
Alternatively you can use the script to achieve it (which will work on Windows as well), for more details please see: Autoplay Embedded Youtube Videos
Yep. There are software players for Android, WebOS and Windows. The most common is Windows, which as stated will use em edded IE to show web content. I believe the response above should likely work as I’ve used it to get past other video problems encountered using the direct link (inability to hide navigation, related videos).
