c# – YouTube直接上传 – OutOfMemory例外

每当我尝试使用YouTube API通过直接上传来上传大型视频时.我得到一个OutOfMemory异常.有什么办法可以摆脱这个吗? YouTube API没有说明使用直接上传的视频大小限制.

我放弃了直接上传.现在我尝试了可恢复的上传方式.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 kilobytem_ResumableUploader.AsyncOperationCompleted += new AsyncOperationCompletedEventHandler(m_ResumableUploader_AsyncOperationCompleted);m_ResumableUploader.AsyncOperationProgress += new AsyncOperationProgressEventHandler(m_ResumableUploader_AsyncOperationProgress);YouTubeAuthenticator = new ClientLoginAuthenticator(“YouTubeUploader”,ServiceNames.YouTube,”kjohnson@resoluteinnovations.com”,”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; }}

谁能告诉我有什么问题?我的2 GB视频无法上传.

解决方法 我收到403 Forbidden错误的原因是因为我没有传入:

>用户名&密码
>开发人员密钥

上传代码中未使用/发送上述代码中的请求变量.因此我正在进行未经授权的上传.
