AVAssetResourceLoader

This is a fork from AVAssetResourceLoader. Why? Big thanks to LeshkoApps, they have made a great job and provided mechanism to cache playable content of AVPlayer. But it was limited to Yandex.Disk cloud service only. So I decided to make it more universal to use with any service/http client.

There are two sample applications:

1. It uses Yandex.Disk cloud service for streaming and caching audio files.
2. It uses AFNetworking framework and video from http://www.sample-videos.com .

Tutorial

0. Import next files to your project:

LSContentInformation.h
LSContentInformation.m
LSDataResonse.h
LSDataResonse.m
LSFilePlayerResourceLoader.h
LSFilePlayerResourceLoader.m
LSPlayerResourceLoaderDelegate.h
LSPlayerResourceLoaderDelegate.m

1. Implement an datasource that confirms LSFilePlayerResourceLoaderDataSource protocol. (HTTPManager and YDSession+LSFilePlayerResourceLoaderDataSource in samples)
2. create LSPlayerResourceLoaderDelegate instance using the datasource
3. use LSFileScheme while creating fileURL
4. use LSPlayerResourceLoaderDelegate instance as asset.resourceLoader delegate

Here is the code:

	// 2. create LSPlayerResourceLoaderDelegate instance using instance that confirms LSFilePlayerResourceLoaderDataSource protocol
	self.resourceLoaderDelegate = [[LSPlayerResourceLoaderDelegate alloc] initWithDataSource:[HTTPManager sharedManager]];
	
	// 3. use LSFileScheme while creating fileURL
	NSURL *fileURL = [[NSURL alloc] initWithScheme:LSFileScheme host:BaseHost path:@"/video/mp4/720/big_buck_bunny_720p_50mb.mp4"];
	
	AVURLAsset *asset = [AVURLAsset URLAssetWithURL:fileURL options:nil];
	
	// 4. use LSPlayerResourceLoaderDelegate instance as asset.resourceLoader delegate
	[asset.resourceLoader setDelegate:self.resourceLoaderDelegate queue:dispatch_get_main_queue()];
	
	AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:asset];
	
	self.player = [[AVPlayer alloc] initWithPlayerItem:item];
	[self.player play];
