Actionscript 3 as3将视频转换为byteArray

我正在尝试使用as3 api（

FacebookMobile.uploadVideo

）将视频上载到facebook，该api将视频作为

fielerefrance

或

byteArray

接受。a遵循示例@创建

byteArray

i ma在解压缩字节数组时出现2058错误（这可能是因为我没有压缩它，但示例中的adobe也没有）。 如果我把这一点注释掉，我会得到一个

353，你必须选择一个视频文件从Facebook上传
错误。
字节数组代码：

public function UICompleteHandler(event:MediaEvent):void
{
    trace("Welcome back from the camera");
    var media:MediaPromise = event.data;
    trace("file info "+media.file.url  + " - " + media.relativePath + " - " + media.mediaType);
    filePath = media.file.url;
    trace("Object encoding is: " + inBytes.objectEncoding + "\n\n" + "order file: \n\n");
    readFileIntoByteArray(filePath, inBytes); 
    trace("length 1:   "+inBytes.length);
    trace("position 1: "+inBytes.position);
    inBytes.position = 0; // reset position to beginning 

    //inBytes.uncompress(CompressionAlgorithm.DEFLATE); 

    trace("position 2:  "+inBytes.position);
    inBytes.position = 0;    //reset position to beginning 
}
private function readFileIntoByteArray(fileName:String, data:ByteArray):void 
{ 
     var inFile:File = new File(fileName);
     trace ("file to byte array  "+  inFile.url);
     trace ("file name var : "+fileName);

     inStream.open(inFile , FileMode.READ);
     inStream.readBytes(data); 
     inStream.close(); 
}

句柄上载代码：

public function handleUpload(ev:TouchEvent)
{
    trace ("posting to facebook - FileName: "+  accessCamera.fileName + " - FilePath: " + accessCamera.filePath);
    var params:Object ={  
        title:'test upload on FB api',
        description:'test upload on FB api',
        fileName: accessCamera.fileName,
        video: accessCamera.inBytes
    }

    trace ("params.video = "+params.video);

    FacebookMobile.uploadVideo('me/videos', onComplete, params);
}

private function onComplete( result:Object, fail:Object ):void {
    trace("facebook post onComplete called" );
    if (result)
    {
        //result.id is id of post that was just posted
        trace ("great");
    }
    else if (fail)
    {
        trace("post Failed");  
        trace('code: '+fail.error.code); 
        trace('message: '+fail.error.message);
        trace('type: '+fail.error.type); 
    }
}

当我追踪
参数视频时
会得到大量随机字符。问题似乎在于facebook似乎没有将
bytearray
（如果我成功地创建了它）视为视频
 adobe示例在写入字节时进行解压缩。试着在写的时候解压，看看解压是否仍然有问题。此外，在尝试上载之前，请更新您的问题，以包括params.video的跟踪。您的意思是将其放入
readFileIntoByteArray
方法中？当我跟踪
params.video
时，我在输出窗格中得到了大量随机字符。很抱歉，回复晚了。我与笔记本电脑分开了一天。我还尝试移动
解压
，但没有成功
