Don't need to know Flash; It can play FLVs and MOV, MP4, M4A, MP4V, 3GP, 3G2 if they contain H.264 video and/or HE-AAC encoded audio (basically whatever the Flash Player can work with). All the information is loading dynamic via Flash Parameters(same technology like youtube and other popular video players). Which means you don't need any XML files, you just set up the player and the parameters in the HTML file you embed it iDescription text formatted via css. Controls: play button , pause button, hd button, info button, seek bar, time(current time , total time) , mute button , volume button , full screen button, right click menu controls, load picture as first keyframe , preloader. Auto resize to every video size. You don't need to resize the video file with special programs or open the fla file to change the size, the player makes this for you.
