AVPlayer is Not Playing From NSCachesDirectory? - iphone

Question

Hi I am Trying to Play Video Files From NSCachesDirectory. The Player is not loading the Files from NSCachesDirectory in videoView layer.
Is it Possible to play Video from cacheDirectory Memory?
Please suggest me...
I have tried this..
NSArray *myPathList = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDir = [myPathList objectAtIndex:0];
NSString *songPath = [[NSString alloc] initWithString: [cachesDir stringByAppendingPathComponent:[NSString stringWithFormat:#"Song.%#", downloadURL]]];
NSURL *pathurl = [[NSURL alloc] initFileURLWithPath:songPath];
NSLog(#"--pathurl---%#",pathurl);
avPlayer =[AVPlayer playerWithURL:pathurl];
self.avPlayerLayer =[AVPlayerLayer playerLayerWithPlayer:avPlayer];
if ( !([avPlayer status] == AVPlayerStatusReadyToPlay) && (dataReceivedSoFar.length >10000))
{
avPlayerLayer.frame =CGRectMake(0, 0, 320, 450);
[[self.videoView layer] addSublayer:avPlayerLayer];
[avPlayer play];
NSLog(#"Video IS Playing");
[alert dismissWithClickedButtonIndex:0 animated:YES];
}

Answer 1

KVO approach.
Add observer:
self.player = [AVPlayer playerWithURL:url];
[self.player addObserver:self forKeyPath:#"status" options:0 context:&PlayerStatusContext];
Observing value
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
change:(NSDictionary *)change context:(void *)context {
if (context == &PlayerStatusContext) {
AVPlayer *thePlayer = (AVPlayer *)object;
if ([thePlayer status] == AVPlayerStatusFailed) {
NSError *error = [self.player error];
// Respond to error: for example, display an alert sheet.
return;
}
// Deal with other status change if appropriate.
if ([thePlayer status] == AVPlayerStatusReadyToPlay) {
[self play];
}
}
// Deal with other change notifications if appropriate.
[super observeValueForKeyPath:keyPath ofObject:object
change:change context:context];
return;
}
Playing:
- (IBAction)play:sender {
[self.player play];
}
EDITING:
As awolCZ said AVPlayer can not play partially downloaded files. But you could use something like http://test.com/test.mp3 for URL.

I'm not sure that [avPlayer status] == AVPlayerStatusReadyToPlay returns YES in this case. It takes some time for AVPlayer to load the item. You should can play immediately even if it's better way to track AVPlayer.status using KVO.

EDIT: Try it this way (quick win):
NSArray *myPathList = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDir = [myPathList objectAtIndex:0];
NSString *songPath = [[NSString alloc] initWithString: [cachesDir stringByAppendingPathComponent:[NSString stringWithFormat:#"Song.%#", downloadURL]]];
NSURL *pathurl = [[NSURL alloc] initFileURLWithPath:songPath];
NSLog(#"--pathurl---%#",pathurl);
avPlayer =[AVPlayer playerWithURL:pathurl];
self.avPlayerLayer =[AVPlayerLayer playerLayerWithPlayer:avPlayer];
avPlayerLayer.frame =CGRectMake(0, 0, 320, 450);
[[self.videoView layer] addSublayer:avPlayerLayer];
[avPlayer play];
