AVFoundationMBS.resourceLoaderDidCancelLoadingRequest(resourceLoader as AVAssetResourceLoaderMBS, loadingRequest as AVAssetResourceLoadingRequestMBS)
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
event | AVFoundation | MBS AVFoundation Plugin | 14.0 | ✅ Yes | ❌ No | ❌ No | ❌ No |
resourceLoader: The resource loader.
loadingRequest: The loading request that has been cancelled.
Previously issued loading requests can be cancelled when data from the resource is no longer required or when a loading request is superseded by new requests for data from the same resource.
For example, if to complete a seek operation it becomes necessary to load a range of bytes that's different from a range previously requested, the prior request may be cancelled while the delegate is still handling it.
Available in OS X v10.9 and later.
AVFoundationMBS.resourceLoaderShouldWaitForLoadingOfRequestedResource(resourceLoader as AVAssetResourceLoaderMBS, loadingRequest as AVAssetResourceLoadingRequestMBS) as boolean
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
event | AVFoundation | MBS AVFoundation Plugin | 14.0 | ✅ Yes | ❌ No | ❌ No | ❌ No |
resourceLoader: The resource loader object that is making the request.
loadingRequest: The loading request object that contains information about the requested resource.
Returns true if your delegate can load the resource specified by the loadingRequest parameter or false if it cannot.
The resource loader object calls this method when assistance is required of your code to load the specified resource. For example, the resource loader might call this method to load decryption keys that have been specified using a custom URL scheme.
Returning true from this method, implies only that the receiver will load, or at least attempt to load, the resource. In some implementations, the actual work of loading the resource might be initiated on another thread, running asynchronously to the resource loading delegate; whether the work begins immediately or merely soon is an implementation detail of the client application.
You can load the resource synchronously or asynchronously. In both cases, you must indicate success or failure of the operation by calling the finishLoadingWithResponse or finishLoadingWithError: method of the request object when you finish. If you load the resource asynchronously, you must also store a strong reference to the object in the loadingRequest parameter before returning from this method.
If you return false from this method, the resource loader treats the loading of the resource as having failed.
Available in OS X v10.9 and later.
