Video Format for webplayer build

What is the Video format supported by the Webplayer build? Only .ogg files?

Thanks,

Movie texture will help to play movie in web player. Movie Textures can play (usually .mov, .mpg, .mpeg, .mp4, .avi, .asf) file formats. If you’re playing movie using WWW you can prefer .ogg too.
