I'm currently using UIImagePickerController to record a video and save it. I'm using 1080p quality so a short video can still be large. In my app, the user can send the videos they recorded by email, so having a large video isn't ok. Is there any way I can save 2 versions of the video(high quality and low quality), one saved at ~/app-folder/video-name.mov, then the other at ~/app-folder/video-name-SD.mov? Or save the HD video but have an SD version somehow? All solutions are welcome, not just saving an SD version. Here is what i'm doing:
- (BOOL)startCameraControllerFromViewController:(UIViewController *)controller
usingDelegate:(id)delegate {
//setup for video recording
//imagePickerWithout is a subclass of UIImagePicker
imagePickerWithout *cameraUI = [[imagePickerWithout alloc] init];
cameraUI.videoQuality = UIImagePickerControllerQualityTypeHigh;
[controller presentViewController:cameraUI animated:YES completion:nil];
return YES;
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
//setup video
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfURL:videoURL];
//pseudocode :(
NSData *lowQualData = [NSData LOW_QUALITY_VERSION_OF_URL:videoURL];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
int random = arc4random() % 80085;
NSString *tempPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@_%@_%@_%d.mov", self.person.first, self.person.last, self.person.age, random]];
NSString *sdPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@_%@_%@_%dLOWQUAL.mov", self.person.first, self.person.last, self.person.age, random]];
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL success = [videoData writeToFile:tempPath atomically:YES];
BOOL success = [lowQualData writeToFile:sdPath atomically:YES];
NSError *error = nil;
[_managedObjectContext save:&error]
}
[self dismissViewControllerAnimated:YES completion:nil];
}
