upload video to facebook from air android app - actionscript-3

Question

i am attempting (for some time now) to upload a video to Facebook from an air for android app. i have recorded the video on the device, saved it to the device and have the path to the video stored in a string. i was advised to convert the video to byteArray and pass that into the FacebookMobile.uploadVideo method of the as3 Facebook api which i attempted to do but am getting a 353 You must select a video file to upload. error (from Facebook i presume).
file to byteArray
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();
}
Upload to Facebook(attempt)
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);
}
}
when i uncomment the trace params.video i get a huge amount of random characters which i thought to be the data of the byteArray
any guidance or help from anyone would be appreciated
