I am using .NET to create a video uploading application. Although it's communicating with YouTube and uploading the file, the processing of that file fails. YouTube gives me the error message, "Upload failed (unable to convert video file)." This supposedly means that "your video is in a format that our converters don't recognize..."

I have made attempts with two different videos, both of which upload and process fine when I do it manually. So I suspect that my code is a.) not encoding the video properly and/or b.) not sending my API request properly.

Below is how I am constructing my API PUT request and encoding the video:

Any suggestions on what the error could be would be appreciated.

Thanks

P.S. I'm not using the client library because my application will use the resumable upload feature. Thus, I am manually constructing my API requests.

Documentation: http://code.google.com/intl/ja/apis/youtube/2.0/developers_guide_protocol_resumable_uploads.html#Uploading_the_Video_File

Code:

            // new PUT request for sending video
            WebRequest putRequest = WebRequest.Create(uploadURL);

            // set properties
            putRequest.Method = "PUT";
            putRequest.ContentType = getMIME(file); //the MIME type of the uploaded video file

            //encode video
            byte[] videoInBytes = encodeVideo(file); 

     public static byte[] encodeVideo(string video)
     {
        try
        {
            byte[] fileInBytes = File.ReadAllBytes(video);
            Console.WriteLine("\nSize of byte array containing " + video + ": " + fileInBytes.Length);
            return fileInBytes;
        }
        catch (Exception e)
        {
            Console.WriteLine("\nException:  " + e.Message + "\nReturning an empty byte array");
            byte [] empty = new byte[0];
            return empty;
        }
     }//encodeVideo

            //encode custom headers in a byte array
            byte[] PUTbytes = encode(putRequest.Headers.ToString());

          public static byte[] encode(string headers)
          {            
              ASCIIEncoding encoding = new ASCIIEncoding();
              byte[] bytes = encoding.GetBytes(headers);
              return bytes;
           }//encode 

            //entire request contains headers + binary video data
            putRequest.ContentLength = PUTbytes.Length + videoInBytes.Length;

            //send request - correct?
            sendRequest(putRequest, PUTbytes);
            sendRequest(putRequest, videoInBytes);

     public static void sendRequest(WebRequest request, byte[] encoding)
    {
        Stream stream = request.GetRequestStream(); // The GetRequestStream method returns a stream to use to send data for the HttpWebRequest.

        try
        {
            stream.Write(encoding, 0, encoding.Length);

        }
        catch (Exception e)
        {
            Console.WriteLine("\nException writing stream: " + e.Message);
        }
     }//sendRequest
