GData youtube video upload mancante audio issue

Question

Sto usando il seguente codice per caricare il file .mov su youtube. Carica con successo ma il video non ha audio. Per favore dimmi se sto facendo qualcosa di sbagliato ....

- (void)uploadVideoFile { 

    NSString *devKey = @"AI39si4w9QSgQj1JzNxzuiHhFbTm2iLt3mRerGh0UNvlryRPGgQhgIaJA8l95j4YwdC1jBIz6_JaX8eJm2GMgE06FtvIu7E9Sg"; 

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

    NSString *username = txtYName.text; 

    NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username]; 

    // load the file data 
    NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/movie.mov"]] retain]; 
    NSData *data = [NSData dataWithContentsOfFile:path]; 
    NSString *filename = [path lastPathComponent]; 

    // gather all the metadata needed for the mediaGroup 
    NSString *titleStr = txtName.text; 
    GDataMediaTitle *title = [GDataMediaTitle textConstructWithString:titleStr]; 

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

    NSString *descStr = @"this is just test"; 
    GDataMediaDescription *desc = [GDataMediaDescription textConstructWithString:descStr]; 

    NSString *keywordsStr = @"SuperShredBros"; 
    GDataMediaKeywords *keywords = [GDataMediaKeywords keywordsWithString:keywordsStr]; 

    BOOL isPrivate = NO; 

    GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup]; 
    [mediaGroup setMediaTitle:title]; 
    [mediaGroup setMediaDescription:desc]; 
    [mediaGroup addMediaCategory:category]; 
    [mediaGroup setMediaKeywords:keywords]; 
    [mediaGroup setIsPrivate:isPrivate]; 

    NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:path 
              defaultMIMEType:@"video/quicktime"]; 

    // create the upload entry with the mediaGroup and the file data 
    GDataEntryYouTubeUpload *entry; 
    entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup 
                 data:data 
                MIMEType:mimeType 
                 slug:filename]; 

    SEL progressSel = @selector(ticket:hasDeliveredByteCount:ofTotalByteCount:); 
    [service setServiceUploadProgressSelector:progressSel]; 

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

    [self setUploadTicket:ticket]; 
// [self updateUI]; 
} 

per favore aiutatemi. Grazie in anticipo.

Answer 1

penso che YouTube supporti i file video in formato flv e mp4. quindi per favore cambia mimetype. Spero che otteniate risultati attesi.

Answer 2

penso che è necessario modificare il tipo MIME come di seguito

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

Questa cosa funziona bene per me e anche un'altra cosa sto caricando file .mov non solo .mp4 o .m4a o FLV

Answer 3

seguito dovrebbe aiutare:

GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup]; 
[mediaGroup setMediaTitle:title]; 
[mediaGroup setMediaDescription:desc]; 
[mediaGroup addMediaCategory:category]; 
[mediaGroup setMediaKeywords:keywords]; 
[mediaGroup setIsPrivate:NO]; 

NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:outputURL.relativePath defaultMIMEType:@"video/quicktime"]; 

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

SEL progressSel = @selector(ticket:hasDeliveredByteCount:ofTotalByteCount:); 
[service setServiceUploadProgressSelector:progressSel]; 

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

Answer 4

modificare l'impostazione di uscita audio .... dovrebbe essere come questo .....

audioOutputSettings = [NSDictionary dictionaryWithObjectsAndKeys: 
           [ NSNumber numberWithInt: kAudioFormatMPEG4AAC ], AVFormatIDKey, 
           [ NSNumber numberWithInt: 1 ], AVNumberOfChannelsKey, 
           [ NSNumber numberWithFloat: 44100.0 ], AVSampleRateKey, 
           [ NSNumber numberWithInt: 64000 ], AVEncoderBitRateKey, 
           [ NSData dataWithBytes: &acl length: sizeof(acl) ], AVChannelLayoutKey, 
           nil];
