1. Mime Player For Firefox

I cannot get my mp4 video to play in Firefox - it simply says ' No video with supported format and MIME type found'. Here's my HTML..

Pocket by Firefox. Save content. Absorb knowledge. Your Firefox Account. Make the most of your Firefox experience, across every device. Firefox for Enterprise. Same speed and safety you trust, designed just for business. Firefox for Fire TV. Watch videos and browse the internet on your Amazon Fire TV. What solved it was to go in Firefox’ URL bar and type about:config, and there set media.gstreamer.enabled to true.

The video plays well in other browsers. I have read other similar questions here on Stackoverflow and some people are saying that FF just will not play mp4 video at all due to licensing..

That assumed therefore, could anybody please suggest either a fix or an alternative video format that plays universally across browsers and how I would convert it?

I am hosting with hostgator and I have checked the list of mime types and mp4 is listed there so I dont think it is that.

Pcunlocker full version free. You should use .ogg for firefox and opera, according to w3schools you can include both formats to make it work on all modern browsers

Here you have some info about compatibility between video/audio formats :

I solved this - the commenter was correct I need to run both mp4 and ogg videos. To do this step-by-step including converting mp4 to ogg for free using VLC media player see this video http://www.youtube.com/watch?v=vNxb6bnTpP0

What Are MIME Types?

A Multi-Purpose Internet Mail Extension (eg. “audio/x-mpegurl”), also known as a MIME, is type of Internet standard originally developed to allow the exchange of different types of data files through e-mail messages. MIME types like audio/x-mpegurl are classified into specific data categories such as Video, Audio, Image, and many more. This categorization provides instructions to your computer or mobile device about how these files should be opened / viewed.

Why Do I Need MIME Types Like audio/x-mpegurl?

Categorizing MIME types like audio/x-mpegurl into a data type such as “Audio” allows your e-mail client or Internet browser to display the content as intended. For example, when you attach a digital camera photo file to an e-mail, an Image MIME type will be associated with that file to allow your recipient to view the photograph.

Here's how it works: Web servers (computers that host websites and e-mail) insert a set of MIME instructions into the beginning of a data transmission, such as an e-mail message or webpage, in the following format:

Content-Type: audio/x-mpegurl

[Format Explanation: The MIME type, which in this example is “Audio”, is separated by a forward slash (“/”) and followed by a subtype.]

This set of instructions tells your client application, such as an e-mail program (eg. Microsoft Outlook, Apple Mail) or web browser (eg. Google Chrome, Mozilla Firefox), which “player application” should be used to properly display the audio/x-mpegurl content.

Many modern web browsers include built-in components to display common data types such as image players (eg. GIF, JPEG), Adobe Flash Player, Javascript, and many more. Other less-common types of players must be downloaded separately in order to properly display the MIME content.

What Are The Most Common Problems Associated With audio/x-mpegurl?

Sometimes you’ll find that your web browser or e-mail client is unable to properly display your audio/x-mpegurl content. This could be due to one of two reasons:

1. You are missing the proper Audio “player software” to display the audio/x-mpegurl content.

2. Your Windows Registry contains an incorrect file extension (eg. XLS, PDF) association with the audio/x-mpegurl MIME type.

How To Fix audio/x-mpegurl Issues

Do I have the audio/x-mpegurl “player application” installed?

The first step in troubleshooting issues with opening audio/x-mpegurl content is to first make sure that you have the correct “player application” installed for this MIME type. Because there can be several (or even hundreds) of related software applications to audio/x-mpegurl, it is very difficult for us to compile a comprehensive list.

Therefore, a key strategy in determining the correct application is to look for clues on what software programs might be related to audio/x-mpegurl. Look at the naming of the subtype for clues about a related program (eg. Word, Excel) or software developer name (eg. Microsoft).

Furthermore, if you’ve been sent MIME type audio/x-mpegurl as an e-mail attachment, look for the file extension of the attached file. This file extension (eg. M3U, etc.) can provide you with a clue of what “player application” is associated with this Audio MIME. Take a look at our file extension list below to see if there are any clues to finding the right “player application”.

Do I have broken audio/x-mpegurl file associations?

The second step in troubleshooting audio/x-mpegurl issues is making sure that you have correct file associations in the Windows Registry. Installing and uninstalling programs can lead to incorrect file associations with audio/x-mpegurl. Take a look at your Windows Registry settings to ensure that the MIME type is correctly associated with the “player application” and file extension.

WARNING: DO NOT edit the Windows Registry unless you are an advanced computer user with experience editing the Registry. Making an error in editing the Registry can create irreversible damage to your PC.

If you are not comfortable editing the Windows Registry, we highly recommend using an automated registry cleaning program, or taking you computer to a qualified professional.
