YouTube-API upload files without any error (C#)

Question

I'm using the .net nuget (Google.Apis.YouTube.v3) from Google for the API calls. Everything works so far (getting playlists, video informations and so on..). But when I try to upload a video it finishes within seconds and nothing happens. upload_ResponseReceived is never called, and upload_ProgressChanged is only called twice with the following output: 1) Bytes sent: 0, Status: Starting, Exception: after a while 2) Bytes sent: 0, Status: Failed, Exception: System.Threading.Tasks.TaskCanceledException: A task was canceled.

Sample Code:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Upload;
using Google.Apis.Util.Store;
using Google.Apis.YouTube.v3;
using Google.Apis.YouTube.v3.Data;

namespace UploadTest
{
    class Program
    {
        static void Main(string[] args)
        {
            UserCredential credential;
            using (FileStream stream = new FileStream("client_secrets.json", FileMode.Open, FileAccess.Read))
            {
                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeUpload },
                    "user",
                    CancellationToken.None,
                    new FileDataStore("YouTube.Auth.Store")).Result;
            }
            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
            });
            var video = new Video();
            video.Snippet = new VideoSnippet();
            video.Snippet.Title = "Default Video Title";
            video.Snippet.Description = "Default Video Description";
            video.Snippet.Tags = new string[] { "tag1", "tag2" };
            video.Snippet.CategoryId = "22"; // See https://developers.google.com/youtube/v3/docs/videoCategories/list
            video.Status = new VideoStatus();
            video.Status.PrivacyStatus = "unlisted"; // or "private" or "public"
            var filePath = @"E:\video.mp4"; // Replace with path to actual movie file.
            using (var fileStream = new FileStream(filePath, FileMode.Open))
            {
                var videosInsertRequest = youtubeService.Videos.Insert(video, "snippet,status", fileStream, "video/*");
                videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
                videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;
                videosInsertRequest.Upload();
            }
            Console.ReadLine();
        }

        private static void videosInsertRequest_ResponseReceived(Video obj)
        {
            Debug.WriteLine("Video has been uploaded! ID: {0}",obj.Id);
        }

        private static void videosInsertRequest_ProgressChanged(IUploadProgress obj)
        {
            Debug.WriteLine("Bytes sent: {0}, Status: {1}, Exception: {2}", obj.BytesSent, obj.Status, obj.Exception);
        }
    }
}

Any idea what I could be doing wrong?

What the returned object (IUploadProgress) contains? What Exception and Status properties contain? — peleyal

OK, I think that you have connection issues, all you have to do is changing the chunk size to a smaller size, so your code should look something like that:

const int KB = 0x400;
var minimumChunkSize = 256 * KB;

var videosInsertRequest = youtubeService.Videos.Insert(video, 
    "snippet,status", fileStream, "video/*");
videosInsertRequest.ProgressChanged +=
    videosInsertRequest_ProgressChanged;
videosInsertRequest.ResponseReceived += 
    videosInsertRequest_ResponseReceived; 
// The default chunk size is 10MB, here will use 1MB.
videosInsertRequest.ChunkSize = minimumChunkSize * 4; 
videosInsertRequest.Upload();
