HTML5 Video Tag

[Rob]

When adding HTML5 video tag to the editor, it strips out the controls preload attributes:
<video id="video" poster="myposter.jpg" src="myvideo.mp4" controls preload></video>

Any suggestions? 

Thanks

Hello Chuck,

The content area of RadEditor is an editable IFRAME which uses the rich text editing engine of the browser under which it operates and this is a browser behavior. The XHTML specification does not allow tag attributes without values and for this reason the browser strips them.

You can reproduce the same issue in an editable iframe as well as in other web based competitors' editors.

All the best,

Hey not sure if you ever resolved this for anyone out there who runs in to it also I was able to get around this limitation by making the attribute equal to itself...

So controls="controls" and autoplay="autoplay" for example. I tried also leaving them null or making them equal to true but both of those seemed to cause performance issues. The former option worked the best and worked on IOS and Android devices and all A-grade browsers as well as IE 6/7/8.

Hello,

Thank you for sharing your discovery with the community. Indeed, if the HTML attributes have values the rich text engine of the browser will not strip them.

Meanwhile, 5+ years later and there is still a bug in the RadEditor's Media Manager. You can enter whatever values you want for various properties, but none of them ever get placed into the inserted html.

Hi David,

The media manager is working with and inserting the obsolete embed and object tags and the properties applies to these tags are deprecated and not supported by the modern browsers. That's why I created the Inserting a Video Tag via the Media Manager instead of the default Object/Embed ones article, to provide an alternative way of inserting the modern video media tags.

If you want to see a redesigned and updated Media Manager, please file your feature request in the Feedback portal.

You may also find useful the Insert External Video dialog too.
