How is it possible to upload the best quality video?

Full Quality For Video Upload

• Im picking a video from UIImagePicker, the video is then being uploaded to my server. I want the quality of the video to remain the same. As of right now the video has a bit less quality compared to the one i took directly off my phone, and it is a smaller resolution. here is my code: -(IBAction)video:(id)sender{ UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie, nil]; picker.allowsEditing = YES; picker.wantsFullScreenLayout = YES; picker.videoQuality = UIImagePickerControllerQualityTypeHigh; [self presentModalViewController:picker animated:YES]; } - (NSData *)generatePostDataForData:(NSData *)uploadData { // Generate the post header: NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"upload[file]\"; filename=\"somefile\"\r\nContent-Type: application/octet-stream\r\nContent-Transfer-Encoding: binary\r\n\r\n" encoding:NSASCIIStringEncoding]; // Get the post header int ASCII format: NSData *postHeaderData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; // Generate the mutable data variable: NSMutableData *postData = [[NSMutableData alloc] initWithLength:[postHeaderData length] ]; [postData setData:postHeaderData]; // Add the image: [postData appendData: uploadData]; // Add the closing boundry: [postData appendData: [@"\r\n--AaB03x--" dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]]; // Return the post data: return postData; } - (void)post:(NSData *)fileData { NSData *videoData = fileData; NSString *urlString = @"http://www.site.com/scripts/upload.php"; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]; [request addValue:contentType forHTTPHeaderField:@"Content-Type"]; NSMutableData *body = [NSMutableData data]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\".mov\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:videoData]]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:body]; NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"%@", returnString); } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{ [self dismissModalViewControllerAnimated:YES]; //assign the mediatype to a string NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; //check the media type string so we can determine if its a video NSLog(@"got a movie"); NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; NSData *webData = [NSData dataWithContentsOfURL:videoURL]; [self post:webData]; } setting the pickers quality to high i thought would do it, i guess not. I have the option to export in 720p, but i want iphone 4s's to upload in full 1080p. Any help would be great. Thanks :D

• Answer:

  You can't skip the annoying compression step, UIImagePicker insists on doing it. You can get at the high quality video by using the UIImagePickerControllerReferenceURL key, however the long compression step is a deal breaker for me. So go log a bug, then check out this excellent https://github.com/guicocoa/photopicker-ios.
