还有其他问题上传AVAssetWriter的音频质量低，这就是为什么它无法上传... 。 – objectivecdeveloper

我认为Youtube支持flv和mp4格式的视频文件。所以请更改mimetype。希望你得到预期的结果。

我认为你需要改变MIME类型，如下

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

这件事工作正常，我也一件事我正在上传.mov文件不仅.MP4或.m4a的或者。FLV

以下应该可以帮助您：

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:)];

改变你的输出音频设置....它应该是这样的.....

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];
