no video with supported format and MIME type found. What does this mean and how can I change this

firefox, html, mime, mime-types

Solution

The webserver might not be sending the correct MIME types. Depending on the server you may be able to add a .htaccess file with the following:

AddType video/webm .webm
AddType video/mp4 .mp4

If that doesn't work try searching for "server mime types".

Problem

no video with supported format and MIME type found A huge screen for video is displayed and says the message above. How do I solve this? This happens to me only in Mozilla Fire fox and not on Google Chrome. I am using webm videos and mp4 videos. This is for html5 video.
