A client wants me to post a video on her site. It is in WMV format. I have it embedded, but it is just a block box with controls until you press play. Is there a way to show the first frame instead of the black box?
I believe there is a parameter to use a background image, you'll need screenshot first. The trouble with your code is cross browser and cross platform compatibility. That's why flash players are so popular for video. It eliminates those problems.
If you have to use WMV do a search for some of the Silverlight players.
