I'm working with AVAsset in my app and met next problem. When I'm writing something like this:

AVAsset *audioAsset = [AVAsset assetWithURL:[NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/Hello.mp3", [[NSBundle mainBundle] resourcePath]]]];

its work fine. But when I trying get fresh recorded file from my tmp directory from in app's sandbox like that: 

AVAsset *audioAsset2 = [AVAsset assetWithURL:[NSURL URLWithString:[NSTemporaryDirectory() stringByAppendingPathComponent:[@"speechRecord" stringByAppendingPathExtension:@"m4a"]]]];

it doesn't work too. Even if I trying add video file to asset from sandbox - result is the same. I even tried work with AVURLAsset, but asset always empty too. I need it to mix two audio files between themselves and then merge it with recorded video. If I can do that without AVAssets and there is another way, I will appreciate if You tell me. Or may there is some another function for that?

You create the second URL for audioAsset2 with the URLWithString selector. Your first asset loaded correctly, because you used the fileURLWithPath selector.

If you want to load a file at a given URL always create the NSURL object with the fileURLWithPath selector.

So simply try:

AVAsset *audioAsset2 = [AVAsset assetWithURL:[NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[@"speechRecord" stringByAppendingPathExtension:@"m4a"]]]];
