HTTP Content-Type video/mp4 warning in firefox

Question

I have a video that is embeddedin in a webpage. My htaccess: ``` RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ app.php [QSA,L] AddType video/ogg .ogv AddType video/mp4 .mp4 AddType video/webm .webm ``` HTML: ```

``` I use the mediaelement.js player: ``` $('video').mediaelementplayer(); ``` In firefox the video does not preload and it does not show the preview image. The player is just black. In firebug I get this warning: HTTP "Content-Type" "video/mp4" is not supported. Failed to download media ... Any idea how to solve this problem?

Accepted Answer

Firefox supports Ogg Theora and WebM video. It does not support MP4 (H.264) video.
