Video player to work in normal and mobile website

Hello, We have a video website. We need a player like the one in [login to view URL], it will play in a PC, and in mobiles (iphone, blackberry, android, windows mobile), so it plays everywhere. We need this player to be able to play inside it any video from Youtube, and also our links of videos in .mp4, .flv, and other similar formats. When loading, it should display an screenshot (an image that can be given to the player via php). For the player to know which video to play, it will only use in the embed code an id. Then, internally, the player must call a php file hosted in our server, and it will return all the variables needed, like the youtube video link or the video link and the screenshot, or anything else needed. This project is only for the player. The website is already working, and also a mobile version of the website (just light html) is already waiting for this player to be embed. PS: Additional to this quote, we need to know, as a complement to this, how much would it cost to have an iphone app, a blackberry app, and/or and android app.
