Question I am using Adobe/Macromedia Flash on my web site and regular SWF Flash files are working, but any that incorporate FLV videos are not displaying correctly. What could cause my FLV videos to not display?

Answer If you are using Microsoft Windows 2003 Server, and you are experiencing difficulties getting an Adobe Flash FLV video to display on your web site, then you just have to make a minor adjustment to the IIS configuration on your server. Microsoft has made IIS much more secure by default that previous versions of IIS by making sure that the server will not serve files that do not have a know MIME type defined on the server. There is not a MIME type defined for FLV files by default, so IIS ignores requests for those types of files by default on Windows 2003 Server. The following steps just need to be performed on the web server to allow FLV video files to be served from all sites on the server. Note: be sure to follow just these steps only and do not make any other configuration changes until you complete all these steps.

  • Open the IIS Management Tool (Internet Information Services Manager) on the webserver.
  • Expand the Local Compuer node on the display.
  • Right click on the Web Sites folder and select Properties from the pop-up menu.
  • Click on the HTTP Header tab on the Web Site Properties window.
  • Click the MIME Types button on the window.
  • The MIME Types window will pop-up and you want to click the NEW button.
  • In the Extension field, type in .FLV for the filename extension.
  • In the MIME Type field, type in the text “flv-application/octet-stream”, minus the quotes.
  • Click OK.
  • Click OK.
  • Click OK.
  • If you get a prompt titled, Inheritance Overrides, click the Select All button and then click OK again.
  • If the server does not start displaying FLV files immediately, you may have to stop and then restart the World Wide Web Publishing Service on the server.
Note: if you do not have console level access to your web server, your web host or ISP will need to perform this for you.
