java - 发布视频时总是提示视频格式不受支持

Question

我正在尝试使用图形 API 将视频上传到用户墙。结果始终是错误响应“{”error”:{“message”:“(#352) Video file format is not support”，“type”:“OAuthException”}}”。我尝试了几种不同的视频类型，这些类型都基于此列表受支持，http://developers.facebook.com/docs/reference/api/video/ 。根据我对找到的文档的理解，需要做的就是通过 POST 向“https://graph-video.facebook.com/me/videos”发送多部分表单数据请求。顺便说一句，我已经能够使用类似的技术发布照片。我正在使用的代码如下。它基于 http://developers.facebook.com/blog/post/493/ 处的 PHP 示例。 。我已经能够使用 Facebook 上传机制上传不同的视频，所以我知道这些视频适合 Facebook。访问 token 有效，因为我已使用它通过 Graph API 发布照片。

欢迎对我所缺少的内容提出任何建议!

这是我正在使用的 Java 代码:

File video = new File(pathtovideofile);
DataInputStream dis = new DataInputStream(new FileInputStream(video));
byte[] bytes = new byte[(int)video.length()];           
dis.read(bytes, 0, (int)video.length());

// set up the http client, the http method, and the multipart entity
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://graph-video.facebook.com/me/videos");
MultipartEntity mpEntity  = new MultipartEntity( );

ContentBody cbVideo     = new ByteArrayBody(bytes, "video/mp4", "Video Label");
ContentBody cbMessage     = new StringBody( "New Video" );
ContentBody cbTitle     = new StringBody( "Video Title" );
ContentBody cbAccessToken = new StringBody( accessTokenStr1 );

mpEntity.addPart( "access_token", cbAccessToken );
mpEntity.addPart( "file",         cbVideo        );
mpEntity.addPart( "description",  cbMessage     );
mpEntity.addPart( "title",        cbTitle     );

// put the multipart entity into the request
httppost.setEntity(mpEntity);
// send the request
HttpResponse response = httpclient.execute(httppost);

// get the response entity
HttpEntity resEntity = response.getEntity();
// read the stream and print out the results
InputStream instream = resEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(instream));
String line;
StringBuilder responsestr = new StringBuilder();
while (( line = reader.readLine()) != null) {               
  responsestr.append(line);
}
System.out.println(responsestr.toString());

在 php 中这对我有用。首先将文件上传到服务器，然后尝试使用 Graph API 进行 API 调用。

$fbvideo_upload=move_uploaded_file($_FILES['attach_video']['tmp_name'],$fbvideo_path);
chmod($fbvideo_path,0777);                  
if($fbvideo_upload)
{
    $args = array('message' => $status, "access_token" =>$accesstoken,"file" 
            => '@'.$fbvideo_path, "title"=>$video_title, "description"=>$video_desc);
    $post_url = "https://graph-video.facebook.com/me/videos?access_token=".$accesstoken;
    $ch = curl_init();                  
    curl_setopt($ch, CURLOPT_URL, $post_url);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
    $data = curl_exec($ch);                     
    $data=json_decode($data,true);                      
    if(file_exists($fbvideo_path))
    {                           
        @unlink($fbvideo_path);                         
    }
}
