Hi Ryan, Sorry I have to contact you for this, usually I try and find the answers by myself :) But here it is weird and I don't understand why my <video> tag is stripped in the editor when I switch from Editor/HTML view. First, here is my markup in the Article :

<video autoplay="autoplay" class="videostream"></video>

Based on this https://www.joomlacontenteditor.net/support/faq/editor/video-removed-on-saving I verified : Super Users were already set on "No Filter" in the Global Configuration Also I did check the following : in Plugin Parameters > Media Support VIDEO is set on Yes So I have really no clue of why my <video> tag is stripped... Txs for helping :)

OK, indeed if I add a fake scr="movie.ogg" it works !

But actually, I did not have any bc I was doing something similar to this, namely integrating the webcam to the page... so I don't need the scr attribute :

Txs for the explanation & solution Ryan !

Hi Ryan, I have another issue : now the users have added a <track> tag inside the <video> tag. But it gets stripped even if 1. super user 2. "no filtering" in general configuration 3. added "track" to "extended elements" The only temporary way I found was to disable the "validate html". How can I still have the <track .../ > while having "validate html" on ? Just in case, here is the full html

<div id="videocontainer"> <video controls="controls"
          id="firesidevideo" width="720"> <source
            src="https://www.joomlacontenteditor.net/Marzari_full.mp4" type="video/mp4"> <track
            kind="captions" src="https://www.joomlacontenteditor.net/Marzari.vtt" srclang="en"
            label="English"> </video> </div>
    </div>

Txs!

Hi Ryan,

I have installed & tested : it works fine. I can switch from "Code tab" to "Editor tab" and the <track (...)> Tag is not stripped any more.

Txs for the quick follow-up and the fix ! 🙂
