A short video encoded to WebM using Sorenson Squeeze Pro 8.0.48. Chrome and Opera play the HTML5 webm video with a problem. Firefox 10.0.1 and 11 just display a dimmed window with and "X" in the middle and will not load or play anything. Sorenson is a commercially proven product as confirmed by Chrome and Opera, so what gives with Firefox?

Chosen solution

We have just completed our webm testing with Telestream's Episode Pro 6.2.1.1 and not surprisingly, the same results as Sorenson Squeeze Pro 8.

Chrome, Opera and Safari browsers play HTML5 webm video as expected.

Firefox rigidly enforces the server .htaccess configuration to specifically state Mime Types, then it will/does work.

I'd also like to add that the Sorenson Squeeze Pro 8 webm HTML5 video also plays properly on all Android Mobile devices 2.3.3+. I have confirmed this on my mobile phone as well as at BestBuy with their display models Android 3.1/3.2. The problem is clearly with Firefox.

Make sure that the server sends the file with a supported MIME type (video/webm or video/ogg).
