I'm using next snippet to loadValues synchronously, so loading = NO never fires. And I have the same problem with AVAssetExportSession exportAsynchronously. It's all not working only on device.
NSDictionary *options = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES] forKey:AVURLAssetPreferPreciseDurationAndTimingKey];
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:URL options:options];
NSArray *keys = [NSArray arrayWithObjects:@"duration", @"tracks", nil];
__block bool loading = YES;
[asset loadValuesAsynchronouslyForKeys:keys completionHandler:^(void) {
loading = NO;
}];
while (loading)[[NSRunLoop currentRunLoop] runUntilDate:[[NSDate date] dateByAddingTimeInterval:0.5]];
Please, help! My brain is melting.
Here is the code I use:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"intro" ofType:@"m4v"]];
self.asset = [[AVURLAsset alloc] initWithURL:url options:nil];
NSString *tracksKey = @"tracks";
[self.asset loadValuesAsynchronouslyForKeys:[NSArray arrayWithObject:tracksKey] completionHandler:^{
// Other code here for AVPlayer
}];
I don't use any options or anything of that nature. I'm sure you've seen Apple's documentation example:
