How to Fix No Video with Supported Format and MIME type found Users experience the error ‘ No video with supported format and MIME type found ’ when they try to stream video content on their Firefox browsers. This video can range from Facebook to other platforms such as LiveGo.
A MIME type (now properly called 'media type', but also sometimes 'content type') is a string sent along with a file indicating the type of the file (describing the content format, for example, a sound file might be labeled audio/ogg
, or an image file image/png
).
It serves the same purpose as filename extensions traditionally do on Windows. The name originates from the MIME standard originally used in E-Mail.
Firefox fails to display HTML 5OGG and WebM video formats on the page and displays the error – “No Video with Supported Format and Mime Type Found“
The issue is that the web server doesn’t quite know what to think of these formats and serves them out in the wrong type of format which the browser doesn’t understand. What you need to do is add the correct file types of OGG and WebM for video to the Web Server for those file extensions. MP4 will be Ok as that fomat is more widely adopted.
To fix this issue on Apache you need to add the following content to the ‘.htaccess‘ file which is found in your document root (public_html or htdocs). As it starts with a ‘.’ it is invisible to some browsing apps make sure you have a ‘show invisible files’ settings enabled. Below is the setting for the free FTP client Cyberduck
Just paste this at the very head of the .htaccess file and save:
You can also add these mime types directly in the Apache configuration file ‘mime.types’, this way it will affect all sites that share the same server. Open the file below –
Add in –
Restart Apache –
That should solve any Firefox browser issues. However what if your video/audio files are being served from a cloud style storage solution like Amazon S3, this will also needs mime types added.
There are a few ways to do this – directly in S3 or via an FTP client.
Select the file and in the Properties set the Key and the Value to ‘Content-Type’ and then the required ‘video/extension‘. This doesn’t always take immediate affect on existing files and a replacement upload with a different filename and the correct key/value applied will force it to work in the browser.
Rather than go through the S3 web interface you can create a more user friendly connection to the storage buckets via Cyberduck.
Navigate to the file and ‘Get Info’ (command+i), then set the name and value. Once done one time, files of the same type will automatically get the correct mime types.
In Transmit (preferences > Cloud) you can permanently add in the name/value pairs so all subsequent uploads will contain the mime type.

That’s the lot, all you needed to know about mime content headers but were too afraid too ask. Below is some additional information on setting up the key video players for general use and for responsive design techniques – enjoy!
