no video with support format or mime type found?

Update: it works in Safari

Update: get only audio in Firefox

Still nothing in IE or Chrome (perpetually loading…) It’s a 3 minute video of 7 MB.

This is my embed code:
[video mp4="https://www.salesclosingpower.com/wp/video/bill-bishop-seminar-steam-analogy.mp4" preload="true" autoplay="false" width="290" height="218"]

Update: resolved! (partly)

What it needed was formats for all three file formats to cover all browsers and platforms. I basically looked on https://mediaelementjs.com/ own site to see how they had done their video as I could see it on all browsers.

So, downloaded a converter and uploaded .ogv and .webm files as well as the .mp4 I already had. My code is this:

[video mp4="https://www.salesclosingpower.com/wp/video/bill-bishop-seminar-steam-analogy-h264.MP4" ogg="https://www.salesclosingpower.com/wp/video/bill-bishop-seminar-steam-analogy.ogv" webm="https://www.salesclosingpower.com/wp/video/bill-bishop-seminar-steam-analogy.webm" poster="https://www.salesclosingpower.com/wp/wp-content/uploads/2013/05/poster-steam.jpg" preload="true" autoplay="false" width="290" height="218"] [/video]

I used the [/video] closing tag to cover all bases.

The video and audio work in Firefox, IE, Chrome and Safari, although autoplay=”false” still doesn’t work unfortunately…

Would appreciate anyone letting me know if they have been able to fix that one.

thanks,
