HTTP Live Streaming with AVPlayer in iOS 4.0?
This is a bug in 4.0, but I found a workaround. Here is the correct way to load video with AVPlayer:
AVPlayer *player = [AVPlayer playerWithURL:[NSURL URLWithString:@"http://qtdevseed.apple.com/addemo/ad.m3u8"]];
// now use KVO to decide when it's ready to play
// works in both 4.3 and 4.0.1
The code from StitchedStreamPlayer works in 4.3 but not 4.0.1:
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:[NSURL URLWithString:@"http://qtdevseed.apple.com/addemo/ad.m3u8"] options:nil];
NSArray *tracksKeys = [NSArray arrayWithObjects:kTracksKey, kDurationKey, kPlayableKey, nil];
[asset loadValuesAsynchronouslyForKeys:tracksKeys completionHandler:
^{
NSError *error = nil;
AVKeyValueStatus status = [asset statusOfValueForKey:[tracksKeys objectAtIndex:0] error:&error];
NSLog(@"status=%@,error=%@",(status==AVKeyValueStatusLoaded?@"Loaded":status==AVKeyValueStatusFailed?@"Failed":@"?!"),error);
}];
// output in 4.3: status=Loaded,error=(null)
// output in 4.0.1: status=Failed,error=Error Domain=AVFoundationErrorDomain Code=-11828 "Cannot Open" UserInfo=0x15f2a0 {NSLocalizedFailureReason=This media format is not supported., NSUnderlyingError=0x1599e0 "The operation couldn’t be completed. (OSStatus error -12847.)", NSLocalizedDescription=Cannot Open}
For more info see the old version of StitchedStreamPlayer.

Is it possible to use HTTP Live Streaming with AVPlayer on iOS 4.0? This was clearly a documented feature of 4.0. However, if I run Apple's SitchedStreamPlayer sample code on my 3GS running iOS 4.0.1, clicking "Load Movie" does not play the stream, but gives an error:
2011-06-21 13:14:49.428 StitchedStreamPlayer[680:307] The asset's tracks were not loaded due to an error: Cannot Open
MPMediaPlayer is able to play the same stream on the same device. However, I need a working solution with AVPlayer.
Does anyone know how to get Apple's StichedStreamPlayer code to work on 4.0? The Runtime Requirements say it should work on "iOS 4.0 or later".
Thanks!
