WEBM format videos won't autoplay

I’m trying to autoplay webm video in a post but I can’t.

I tried several codes:

[video width="640" height="360" webm="source***" loop="on" autoplay="on"][/video]

loop=”loop” autoplay=”autoplay”
loop=”on” autoplay=”on”
loop=”y” autoplay=”y”

No matter what I write, it isn’t auto-playing in published post, but it is auto-playing while post editing. video is uploaded on wordpress itself. I’m not using other website

Please, tell me how to fix this.

Should follow this format

I used this:

[video width="640" height="360" webm="" loop="on" autoplay="on"][/video]

and it still doesn’t work

Try turning off all plugins except visual composer … and in normal post, in the TEXT editor, NOT the visual editor, put in the proper format code.

One presumes the link you’re inserting in wdbm=”” actually plays in the web browser if you just load the file by itself ?

Maybe try adding the preload variable?

Does the function work on another theme other than this one?

You might try the WordPress forum also.

I don’t see anything on the docs page saying you need [/video] ?

Maybe somebody else with your issue might pitch in on this one !

It worked

<video src=”http://&#8221; width=”640px” height=”400px” autoplay=”on” controls>

but I added also loop=”on”

thanks for the support
