YouTube直接上传 - OutOfMemory异常

每当我尝试通过使用YouTube API直接上传来上传大型视频时。我得到一个OutOfMemory异常。有什么我可以做的，以摆脱这一点？ YouTube API没有提及使用直接上传的视频大小限制。YouTube直接上传 - OutOfMemory异常

我放弃了直接上传。现在我尝试可恢复的上传方式。我的代码如下。

YouTubeRequest request; 
YouTubeRequestSettings settings = new YouTubeRequestSettings("YouTube Upload", Client Key, "Username", "Password"); 
request = new YouTubeRequest(settings); 
Video newVideo = new Video(); 

ResumableUploader m_ResumableUploader = null; 
Authenticator YouTubeAuthenticator; 

m_ResumableUploader = new ResumableUploader(256); //chunksize 256 kilobyte 
m_ResumableUploader.AsyncOperationCompleted += new AsyncOperationCompletedEventHandler(m_ResumableUploader_AsyncOperationCompleted); 
m_ResumableUploader.AsyncOperationProgress += new AsyncOperationProgressEventHandler(m_ResumableUploader_AsyncOperationProgress); 

YouTubeAuthenticator = new ClientLoginAuthenticator("YouTubeUploader", ServiceNames.YouTube, "[email protected]", "password"); 

//AtomLink link = new AtomLink("http://uploads.gdata.youtube.com/resumable/feeds/api/users/uploads"); 
//link.Rel = ResumableUploader.CreateMediaRelation; 
//newVideo.YouTubeEntry.Links.Add(link); 

System.IO.FileStream stream = new System.IO.FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read); 

byte[] chunk = new byte[256000];int count = 1; 
while (true) { 
    int index = 0; 
    while (index < chunk.Length) { 
     int bytesRead = stream.Read(chunk, index, chunk.Length - index); 
     if (bytesRead == 0) { 
      break; 
     } 
     index += bytesRead; 
    } 
    if (index != 0) { // Our previous chunk may have been the last one 
     newVideo.MediaSource = new MediaFileSource(new MemoryStream(chunk), filePath, "video/quicktime"); 
     if (count == 1) { 
      m_ResumableUploader.InsertAsync(YouTubeAuthenticator, newVideo.YouTubeEntry, new MemoryStream(chunk)); 
      count++; 
     } 
     else 
      m_ResumableUploader.ResumeAsync(YouTubeAuthenticator, new Uri("http://uploads.gdata.youtube.com/resumable/feeds/api/users/uploads"), "POST", new MemoryStream(chunk), "video/quicktime", new object()); 
    } 
    if (index != chunk.Length) { // We didn't read a full chunk: we're done 
     break; 
    } 
}

有谁能告诉我什么是错的？我的2 GB视频无法上传。

你的代码是什么？你试过了什么？什么是您的错误代码？ –

抛出异常在哪里？也许只是提供堆栈跟踪 –

行：m_ResumableUploader.InsertAsync（...）错误：System.Net.WebException：远程服务器返回错误：（403）禁止。 at System.Net.HttpWebRequest.GetResponse（） –

我得到一个403 Forbidden错误的原因是由于事实上，我并没有传递：

用户名密码&
开发人员键

上述代码中的请求变量未在上载中使用/发送。所以我正在做一个未经授权的上传。

有可能是你没有处理你的对象。确保所有一次性的对象是使用语句中..

例如，该代码将上传一个大的zip文件到服务器：

try 
{ 
    using (Stream ftpStream = FTPRequest.GetRequestStream()) 
    { 
     using (FileStream file = File.OpenRead(ImagesZipFile)) 
     { 
      // set up variables we'll use to read the file 
      int length = 1024; 
      byte[] buffer = new byte[length]; 
      int bytesRead = 0; 

      // write the file to the request stream 
      do 
      { 
       bytesRead = file.Read(buffer, 0, length); 
       ftpStream.Write(buffer, 0, bytesRead); 
      } 
      while (bytesRead != 0); 
     } 
    } 
} 
catch (Exception e) 
{ 
    // throw the exception 
    throw e; 
}
