I am using UIImagePickerController
to choose video file from library. And user can upload the video.
Also I am using videoMaximumDuration
property while user wants to capture video and upload it.
I want to know that How can I get the duration of selected video file ? so that I can restrict the user to upload video that has duration more then 20 seconds.
I am able to get some basic info about selected video by this code :
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
selectedVideoUrl = [info objectForKey:UIImagePickerControllerMediaURL];
NSError *error;
NSDictionary * properties = [[NSFileManager defaultManager] attributesOfItemAtPath:selectedVideoUrl.path error:&error];
NSNumber * size = [properties objectForKey: NSFileSize];
NSLog(@"Vide info :- %@",properties);
}
But there is nothing about duration of selected video.
Thanks...
Got the solution : I use AVPlayerItem
class and AVFoundation
and CoreMedia
framework.
#import <AVFoundation/AVFoundation.h>
#import <AVFoundation/AVAsset.h>
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
selectedVideoUrl = [info objectForKey:UIImagePickerControllerMediaURL];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:selectedVideoUrl];
CMTime duration = playerItem.duration;
float seconds = CMTimeGetSeconds(duration);
NSLog(@"duration: %.2f", seconds);
}
