audio video photo path and access method

I hope to know wha开发者_JAVA技巧t is the absolute path of storing audio, video and photos. Are they in a same path?

I know I can use UIImagePicker to access saved photo. Are there standard sdk/frame to access audio video? or I need to construct the codes by myself?

Thanks

Yes: in iOS 4.0, the ALAssetsLibrary API will let you access media directly.
