Playing MP4 videos from Server on IE9 RRS feed

  • Question

  • Hi 

    I am trying to play .mp4 videos from Server on my HTML5 web page, but it's not showing the video.

    I have the MIME type as video/mp4 on the server. I have checked it on Developer tool , its giving me error code 4 which is 

    Encoding not supported by IE9. 

    I have seen .mp4 videos hosted on other webpages playing fine.

    Please provide any assistance if possible.

    Code is like this

    <video width="300" height="162" ><source src=""  type="video/mp4"></video>

    Thanx in advance.

  • Hi,

    Please post questions about website development to the IE Web Developer forum.

    Include with your questions a link to your website, or publicly accessible mashup that shows your issue, or your full page makup and the compete error messages from the developer console. In your case we would need a link to your 'MP4' file.

    It is unclear from you question if you are using a browser on a Windows server version or from a windows client.... IE Runs in Enhanced protected mode on server versions of windows.

    IE11 is the latest version..and it correctly prompts the user If the file contents don't match its extension. Most probably you have a file that has been renamed with a mp4 extension.

    A quick way to troubleshoot issues is to type error messages into your favorite search engine.
