AVAssetResourceLoadingRequest

An AVAssetResourceLoadingRequest object encapsulates information about a resource request issued from a resource loader object.

Overview

When an AVURLAsset object needs help loading a resource, it asks its AVAssetResourceLoader object to assist. The resource loader encapsulates the request information by creating an instance of this object, which it then hands to its delegate object for processing. The delegate uses the information in this object to perform the request and report on the success or failure of the operation.
