A common point overlooked when setting a website live with FLV or F4V videos embedded is setting the MIME types in IIS.  Without doing this you'll be left with a big empty space of nothingness where your video should play.

Without further ado, I present to you a guide to overcome this….

Setting FLV/ F4V MIME type:

  1. Connect via RDP to your server 
  2. Open IIS (start > run > inetmgr OR start > programs > administrative tools > internet information services (IIS) manager)
  3. Expand your computer node
  4. Expand Web Sites node
  5. Right click on the website you want to set the MIME type for and select Properties
  6. Select the HTTP Headers tab
  7. Click on the "Mime Types" button
  8. Click "New"
  9. Set the extension to: .flv
  10. Set the MIMEType to: video/x-flv
  11. Click OK all the way back to your main IIS screen
  12. Restart IIS (right click on your computer node and select "All Tasks" > "Restart IIS" or go to start > run > and type "IISReset"

To set the F4V MIME type, which was introduced as the successor to FLV by Adobe in the most recent versions of Flash, in step 9 and 10 above set the paramters to ".f4v" and "video/mp4" (without the speech marks) consecutively.
