Question

I’m using an imagePickerController to record video. In the imagePickerController:didFinishPickingMediaWithInfo: function I’m trying to set the video to a previously defined MPMoviePlayerController:

if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]){
    NSURL *movieUrl = [info objectForKey:UIImagePickerControllerMediaURL];
    [self.moviePlayer setContentURL:movieUrl]];
}

This is working fine and the video is indeed playing.
But I want to save the file for later use. When I do this and use the saved file for the moviePlayer, nothing happens:

• I’ve tried this (saving the data to a new file)

  NSString *directory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
  NSString *newPath = [directory stringByAppendingPathComponent:@"myMovie.mov"];
  NSData *videoData = [NSData dataWithContentsOfURL:movieUrl];
  [videoData writeToFile:newPath atomically:NO];
  [self.moviePlayer setContentURL:[NSURL URLWithString:newPath]];
  

• or this (copying the temp video file to my document folder)

  NSString *directory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
  NSString *newPath = [directory stringByAppendingPathComponent:@"myMovie.mov"];
  NSFileManager *fileManager = [NSFileManager defaultManager];
  NSError *error = nil;
  [fileManager copyItemAtPath:[videoUrl path] toPath:newPath error:&error];
  [self.moviePlayer setContentURL:[NSURL URLWithString:newPath]];
  

Without any success, even though the file at newPath does exist… What am I doing wrong?

Answer 1

Ok I finally found the issue. The problem was not in fact with the MPMoviePlayerController but with the line:

[self.moviePlayer setContentURL:[NSURL URLWithString:newPath]];

I fixed it by replacing that line with:

[self.moviePlayer setContentURL:[NSURL fileURLWithPath:newPath isDirectory:NO]];

Hope that will help someone else!
