TweetInvi 视频上传失败 "The tweet cannot be published as some of the medias could not be published!"

Question

我遇到 TweetInvi 0.9.9.7 无法上传视频的问题。该视频是一个 9MB 的 MP4 视频，我可以使用网络界面将它上传到 Twitter。我收到的错误消息是：

The tweet cannot be published as some of the medias could not be published!

我使用了 fiddler，可以看到此错误消息是从 API:

返回的

error=segment size must be <= 1.

根据其中一位开发人员的说法，当试图将超过 5MB 的视频上传到 Twitter 并且没有分块发送时，就会发生该错误。 https://twittercommunity.com/t/append-call-in-video-upload-api-giving-error/49067

这是我的代码，我做错了什么吗？上传 5MB 以下的文件可以正常工作，但 official API spec supports video up to 15MB

Auth.ApplicationCredentials = new TwitterCredentials("blahblahblah", "censoring private key", "***private, keep out***", "***beware of dog***");
var binary = File.ReadAllBytes(VideoPath);
Tweet.PublishTweetWithVideo("Here is some tweet text", binary);

最终，我发现了这个无证美女： Upload.CreateChunkedUploader();

它完全公开了我上传这个更大的文件所需的功能。这是我的新工作代码，供可能遇到此问题的其他人使用。

        var chunk = Upload.CreateChunkedUploader(); //Create an instance of the ChunkedUploader class (I believe this is the only way to get this object)

        using(FileStream fs = File.OpenRead(VideoPath))
        {
            chunk.Init("video/mp4", (int)fs.Length); //Important! When initialized correctly, your "chunk" object will now have a type long "MediaId"
            byte[] buffer = new byte[4900000]; //Your chunk MUST be 5MB or less or else the Append function will fail silently.
            int bytesRead = 0;

            while((bytesRead = fs.Read(buffer, 0, buffer.Length)) > 0)
            {
                byte[] copy = new byte[bytesRead];
                Buffer.BlockCopy(buffer, 0, copy, 0, bytesRead);
                chunk.Append(copy, chunk.NextSegmentIndex); //The library says the NextSegment Parameter is optional, however I wasn't able to get it to work if I left it out. 
            }
        }

        var video = chunk.Complete(); //This tells the API that we are done uploading.
        Tweet.PublishTweet("Tweet text:", new PublishTweetOptionalParameters()
        {
            Medias = new List<IMedia>() { video }
        });

重要的收获：

您不能上传大于 5MB 的文件而不先将它们分开。
TweetInvi 已经有一个机制来处理这个限制，我只是找不到它的任何文档。
API 每个视频文件的硬性限制为 15MB。 Despite twitter's support site which claims it can handle up to 512MB

Note: You’ll be prompted if the selected video is not in a supported format. Maximum file size is 512MB. See here for more details about formats.
