f4Player is an open source flash (AS3) video/stream player and library project. It is so small that it is only 13kb and totally free under LGPL license.
I'm still developing it for HTML5 support and JS interface.
I've only tested it with flv, f4v, mp4, stream, live stream, subscribed CDN and it works enough for me for now!
It is under LGPL License.
