I am not sure, how much this code snippet will help - in any case you need to embed the file (ogv in the case below) into a wrapper as follows

 <script type="text/javascript" src="http://s3.amazonaws.com/s3.www.universalsubtitles.org/embed.js">
     ({
         "base_state": {
             "language": "sl"
         },
         "video_url": "http://videos.mozilla.org/serv/brand/Mozilla_Firefox_Manifesto_v0.1.ogv",
         "video_config": {
             "width": 550,
             "height": 310
         }
     })
 </script>

The code is from mozilla.si (worpress-based) page.

Hope it helps.

Firefox doesn't support MP4 via the video tag.
This is only possible via the object or embed tag and if you have a player installed that supports the .mp4 file extension (about:plugins).

Thanks smo, I tried the wrapper and it just embedded a widget type object but not the video.

cor-el - I'm using webm as the video type.

I tried to add the webm video using html 5 but got a "no video with supported format and MIME type" error. I found the code below to add to the .htaccess file as a suggested fix since are using apache. Has anyone tried this?

1. MIME types for Video

AddType video/mp4 mp4 m4v f4v f4p AddType video/ogg ogv AddType video/webm webm AddType video/x-flv flv

This can also happen if the server isn't configured properly to send the file with a supported MIME type.

• AddType audio/webm .webm
• AddType video/webm .webm
