如何解决Twitter API错误“无效媒体”

Question

我正在尝试上传15 MB的视频。在步骤INIT中，成功从服务返回了media_id信息

在APPEND步骤中，我们使用Chunk结构，并成功传递每个块值为4mb的字节数组

在“完成”步骤中，我们成功完成了上传过程

但是，当我们使用STATUS检查货件时，会出现以下错误。

{“ media_id”：1187325998846660609，“ media_id_string”：“ 1187325998846660609”，“ media_key”：“ 7_1187325998846660609”，“ size”：8795782，“ processing_info”：{“ state”：“ Failed”，“ progress_percent”：100 ，“错误”：{“代码”：1，“名称”：“ InvalidMedia”，“消息”：“文件无效”}}}

public class InitModel
    {
        public string media_id { get; set; }
        public string media_id_string { get; set; }
        public string expires_after_secs { get; set; }
    }
