Upload video to youtube error 400 InvalidRequestUriException using GData API

Question

I'm trying to post video to youtube from inside of my iPhone application using the GData API. Here is the code I'm using:

GDataServiceGoogleYouTube* service = [self youTubeService];
[service setYouTubeDeveloperKey:youtubeAppKey];

NSString *username = service.username;
NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username];

NSData *data = [NSData dataWithContentsOfFile:self.videoPath];
NSString *filename = @"My Cool Video";
NSString *titleStr = @"Title";
GDataMediaTitle *mediaTitle = [GDataMediaTitle textConstructWithString:titleStr];

NSString *categoryStr = @"Comedy";
GDataMediaCategory *mediaCategory = [GDataMediaCategory mediaCategoryWithString:categoryStr];
[mediaCategory setScheme:kGDataSchemeYouTubeCategory];

NSString *descStr = @"Description";
GDataMediaDescription *mediaDesc = [GDataMediaDescription textConstructWithString:descStr];

NSString *keywordsStr = @"iOS";
GDataMediaKeywords *mediaKeywords = [GDataMediaKeywords keywordsWithString:keywordsStr];

GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup];
[mediaGroup setMediaTitle:mediaTitle];
[mediaGroup setMediaDescription:mediaDesc];
[mediaGroup addMediaCategory:mediaCategory];
[mediaGroup setMediaKeywords:mediaKeywords];
[mediaGroup setIsPrivate:isPrivate];

NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:self.videoPath
                                           defaultMIMEType:@"video/mp4"];

GDataEntryYouTubeUpload *entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup
                                                                               data:data
                                                                           MIMEType:mimeType
                                                                               slug:filename];

GDataServiceTicket *ticket = [service fetchEntryByInsertingEntry:entry
                                                      forFeedURL:url
                                                        delegate:self
                                               didFinishSelector:@selector(uploadTicket:finishedWithEntry:error:)];
[self setUploadTicket:ticket];

And I'm having this response:

serviceBase: objectFetcher:GTMHTTPUploadFetcher 0x48af0a0 (https://uploads.gdata.youtube.com/resumable/feeds/api/users/myCoolMail@gmail.com/uploads?upload_id=heregoesidiremoved) failedWithStatus:400 data:GDataInvalidRequestUriExceptionException message unavailable

I've tried Google sample code and had the same result. I used device and Simulator (5.0). I've tried prepared video as long as the recorded from iPhone one. I created the Project in the google API section and got an application key.

Please, help me find the solution of the problem!

Answer 1

The problem was here:

NSString *username = service.username;
NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username];

Don't know why is that, but I've changed the userID from "username" to kGDataServiceDefaultUser and the thing started working. So simple and so odd, but it did the trick.

Correct code:

NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:kGDataServiceDefaultUser];
