iphone sdk: Posting Video to Facebook throws format not supported error

Question

I am trying to post videos to my Facebook wall through app but it always gives error " Sorry, the video file you selected is in a format that we don't support. "

I have got permissions for upload_video and pubish_actions too. I don't know what is going wrong.

Here is my code:

 NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData,@"source",
                                   @"video/quicktime", @"contentType",
                                   @"", @"name",
                                   description, @"description",
                                   nil];

    [FBRequestConnection startWithGraphPath:@"me/videos"
                                 parameters:params
                                 HTTPMethod:@"POST"
                          completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
                              if (error.fberrorCategory != FBErrorCategoryUserCancelled) {
                                  [self presentAlertForError:error];
                              }
                              else {
                                  [self showAlert:@"Posted on your wall" title:nil];
                              }
                          }];

Thanks!

Answer 1

the params should be

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, @"video.mov",
                                   @"video/quicktime", @"contentType",
                                   @"Video Test Title", @"title",
                                   @"Video Test Description", @"description",
                       nil];
