Answer 1

It works fine only if you implement the request exactly as specified (even a single space matters)

Finally able to upload the video, Here the 200% working code.

NSString* const kMetaData = @"<?xml version=\"1.0\"?>\r\n<entry xmlns=\"http://www.w3.org/2005/Atom\"\r\nxmlns:media=\"http://search.yahoo.com/mrss/\"\r\nxmlns:yt=\"http://gdata.youtube.com/schemas/2007\">\r\n<media:group>\r\n<media:title type=\"plain\">%@</media:title>\r\n<media:description type=\"plain\">\r\n%@\r\n</media:description>\r\n<media:category\r\nscheme=\"http://gdata.youtube.com/schemas/2007/categories.cat\">%@\r\n</media:category>\r\n<media:keywords>%@</media:keywords>\r\n</media:group>\r\n</entry>\r\n";


- (void)uploadVideo:(NSString *)videoFilePath videoInfo:(NSDictionary*)inVideoInfo
{
    NSData* videoData = [NSData dataWithContentsOfFile:videoFilePath];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:kVideoUploadURL]];
    request.HTTPMethod = @"POST";

    //header values
    [request setValue:kHostHeaderFiels_Upload_Value forHTTPHeaderField:kHostHeaderField_Key];
    [request setValue:[NSString stringWithFormat:@"%@ %@", self.tokenType, self.accessToken] forHTTPHeaderField:kAuthorizationHeaderField_Key];
    [request setValue:@"2" forHTTPHeaderField:kGdataVersionHeaderField_Key];
    [request setValue:videoFilePath.lastPathComponent forHTTPHeaderField:kSlugHeaderField_key];
    [request setValue:[NSString stringWithFormat:kContentTypeHeaderField_Upload_Value, kBoundary_Value] forHTTPHeaderField:kContentTypeHeaderField_Key];
    [request setValue:kConnectionHeaderField_Value forHTTPHeaderField:kConnectionHeaderField_Key];
    [request setValue:kGdataKeyHeaderField_Value forHTTPHeaderField:kGdataKeyHeaderField_Key];

    //Post Data
    NSMutableData* httpBodyData = [NSMutableData data];

    [httpBodyData appendData:[[NSString stringWithFormat:@"--%@\r\n", kBoundary_Value] dataUsingEncoding:NSUTF8StringEncoding]];
    [httpBodyData appendData:[@"Content-Type: application/atom+xml; charset=UTF-8\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    NSString *title, *descrition, *keywords, *category;

    title = [inVideoInfo objectForKey:kVideoTitle];
    descrition = [inVideoInfo objectForKey:kVideoDescription];
    keywords = [inVideoInfo objectForKey:kVideoKeywords];
    category = [inVideoInfo objectForKey:kVideoCategory];

    NSString* metaData = kMetaData;
    metaData = [NSString stringWithFormat:metaData, title, descrition, category, keywords];

    [httpBodyData appendData:[metaData dataUsingEncoding:NSUTF8StringEncoding]]; //Meta Data

    [httpBodyData appendData:[[NSString stringWithFormat:@"--%@\r\n", kBoundary_Value] dataUsingEncoding:NSUTF8StringEncoding]]; //boundary string
    [httpBodyData appendData:[[NSString stringWithFormat:@"Content-Type: video/%@\r\n", videoFilePath.pathExtension] dataUsingEncoding:NSUTF8StringEncoding]];
    [httpBodyData appendData:[@"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [httpBodyData appendData:videoData];
    [httpBodyData appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", kBoundary_Value] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setValue:[NSString stringWithFormat:@"%u", httpBodyData.length] forHTTPHeaderField:kContentLengthHeaderField_Key];

    request.HTTPBody = httpBodyData;

    [NSURLConnection sendAsynchronousRequest:request
                                       queue:[NSOperationQueue new]
                           completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
                               if(connectionError || data == nil)
                               {
                                   self.uploadHandler(NO, nil);
                               }
                               else
                               {
                                   NSXMLParser *xmlparser = [[NSXMLParser alloc] initWithData:data];
                                   xmlparser.delegate = self;
                                   [xmlparser parse];
                               }
                           }];
}
