有没有人使用任何库从浏览器中的网络摄像头录制，然后使用它上传到 YouTube？我认为有一些 Flash/JavaScript 解决方案，我发现一些是 ScriptCam (http://www.scriptcam.com/)、jpegcam (http://code.google.com/p/jpegcam/)、nimbb (http ://nimbb.com/) 和 Viddler (http://developers.viddler.com/documentation/articles/howto-record/)。
有没有人使用过这些库，或者你能推荐其他库吗？
YouTube has an interface for webcam recordings and upload:

However, I read on your question that you are seeking a video hosting service that isn't necessarily YouTube.
I would recommend red5, they allow you to gain full control on both server side, and client side events
