C# YouTube : Google API

March 12, 2011 by C#   Integration   Google API     This post is marked as obsolete.

This week we had the opportunity to do some integration with YouTube for one of our clients - upload, edit, remove and displaying videos all in the "comfort" of their own website.

Initially we thought that we will probably need to do this using raw calls etc to YouTube (which we'd probably wrap into some sexy reusable classes), but luckily Google did all the work for us already via their data API - in a few lines of code one can for example upload a video to YouTube (like you will see in the following post).

Before you continue, you need to download the Google Data API (if you didn't already) and register for a YouTube developer key, you'll also need a username and password to access YouTube.

Lets jump into some code...

You'll need to add the following Google API references to your solution.



The following namespaces (located within the added references) are required:

using Google.YouTube;
using Google.GData.YouTube;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.GData.Extensions.MediaRss;

Next you need to create an instance of the YouTubeRequestSettings class to which we pass all the settings required to connect to YouTube:

YouTubeRequestSettings settings = new YouTubeRequestSettings("applicationName", "developerKey", "userName", "passWord");

Upload a video to YouTube

YouTubeRequest request = new YouTubeRequest(settings);
Video newVideo = new Video();
newVideo.Title = "Test";
newVideo.Tags.Add(new MediaCategory("Animals", YouTubeNameTable.CategorySchema));
newVideo.Description = "Testing Testing Testing";
newVideo.YouTubeEntry.Private = false;
newVideo.YouTubeEntry.MediaSource = new MediaFileSource("C:\\test.wmv", "video/x-ms-wmv");
request.Upload(newVideo);

In the preceding snippet we pass our settings instance to a YouTubeRequest to which we pass a video using its Upload method.

Notice the Tags collection to which we add a MediaCategory - we're required to add our video to at least one category, a list of available categories can be found here.

When uploading large files to YouTube it might be prudent to set the YouTubeRequest's timeout, like see in the following piece of code.

((GDataRequestFactory)request.Service.RequestFactory).Timeout = 9999999;

List your uploaded videos

public IEnumerable<Video> ListMyVideos()
{
    YouTubeRequest request = new YouTubeRequest(settings);
    YouTubeQuery query = new YouTubeQuery(YouTubeQuery.DefaultUploads);
    Feed<Video> feed = request.Get<Video>(query);
    return feed != null ? feed.Entries : null;
}

In the snippet above we essentially create a simple query that returns all the videos the current logged in user (via YouTubeRequestSettings) uploaded to YouTube.

Get a video

public Video GetMyVideo(string uploader, string videoID)
{
    YouTubeRequest request = new YouTubeRequest(settings);
    Uri uri = new Uri(String.Format("http://gdata.YouTube.com/feeds/api/users/{0}/uploads/{1}", uploader, videoID));
    return request.Retrieve<Video>(uri);
}

In the preceding snippet we pass our YouTube username (minus its domain) and the ID of the video we wish to retrieve (you can get a list of videoID's in the snippet ahead of this one).

The video object returned by the Retrieve method (on the request), contains all kinds of useful information about the retrieved video e.g. length of the video, links to generated thumbnails etc.

Remove a video

public void Remove(Video video)
{
    YouTubeRequest request = new YouTubeRequest(settings);
    request.Delete(video);
}

To remove your video from YouTube is quite simple, simply pass the video retrieved from the GetVideo method (like seen in this post) to the Remove method seen above.

Update a video

public void Update(Video video, string title, string description)
{         
    YouTubeRequest request = new YouTubeRequest(settings);
    video.Title = title;
    video.Description = description;
    request.Update(video);
}

Similar to the Remove method, we simply pass our retrieved video to the YouTubeRequest object.

Display a video

Displaying a video is probably the easiest part in the whole process - in the past we used object/embed tags, but I noticed that YouTube migrated to iframes like seen in the following snippet.

<iframe title="YouTube video player" width="640" height="390" src="http://www.youtube.com/embed/somevideoID" frameborder="0" allowfullscreen></iframe>

Note: You can disable "related videos", by passing rel=0 to the url in the iframe eg. http://www.youtube.com/embed/somevideoID?rel=0 or even default it to HD by passing hd=1 to the url eg. http://www.youtube.com/embed/somevideoID?hd=1.

Above that, there is tons of customizations & settings we can set within YouTube itself for our uploaded videos - disabling comments, visibility (private / public / unlisted) etc.

Have fun...

How to get Video URL September 6, 2011 by Saurabh

Hi Thank you for this article. Just 1 question though. How do i get the just uploaded video's URL on YouTube?

Timeout June 30, 2011 by Christoff Truter

Hi Anuradha Thank you for the comment. I did however have the following in the post already: ((GDataRequestFactory)request.Service.RequestFactory).Timeout = 9999999; (Didnt this work for you?) Which works on a per request basis I suspect, In contrast your snippet will set the timeout globally for YouTubeRequests...

Solution For Response Time out June 30, 2011 by Anuradha Jayamanne

When I going to upload a file I got "response Time Out" Error. The solution for it is set the time out value to "settings" as follows. Hope it would be helpful YouTubeRequestSettings settings = new YouTubeRequestSettings("applicationName", "developerKey", "userName", "passWord"); settings.Timeout = 1000000; YouTubeRequest request = new YouTubeRequest(settings); Video newVideo = new Video(); newVideo.Title = "Test"; newVideo.Tags.Add(new MediaCategory("Animals", YouTubeNameTable.CategorySchema)); newVideo.Description = "Testing Testing Testing"; newVideo.YouTubeEntry.Private = false; newVideo.YouTubeEntry.MediaSource = new MediaFileSource("C:\\test.wmv", "video/x-ms-wmv"); request.Upload(newVideo);

Hi Chris Spot on! worked the moment I changed it! Thanks for all your help! Mike

Readonly June 17, 2011 by Christoff Truter

Hi Mike I suspect that the url "http://gdata.youtube.com/feeds/api/videos/x" you're using in your method is the public readonly version. Have a look at the url I use in my GetMyVideo method in this post, its something along the lines of "("http://gdata.YouTube.com/feeds/api/users/user_that_uploaded_the_video/uploads/videoID", "

June 17, 2011 by Mike

Hi Chris My getVideoDetails method is below. public Video getVideoDetails(string key) { YouTubeRequest request = new YouTubeRequest(settings); Uri videoEntryUrl = new Uri("http://gdata.youtube.com/feeds/api/videos/" + key); return request.Retrieve<Video>(videoEntryUrl); } This method is only using a key as its linked to a databse which only contains just that. Thanks for taking the time to take a look! Mike

Hi Mike Can you show me an example of your getVideoDetails method?

Null Reference Pointer June 17, 2011 by Mike

Hi there! Wondered if anyone could offer me any assistance. While deleting a video I keep encountering a "Object reference not set to an instance of an object." error. I have ran a debugging trace and found that both the youtuberequest and video objects were instantiated so it cant be either of these. Am wondering if anyone knows if i am missing something? Sample of code below. YouTubeRequest request = new YouTubeRequest(settings); Video video = getVideoDetails(videoID); request.Delete<Video>(video); getVideodetails simpley performs a get video request. The error always occurs on the request.delete line. Thanks! Mike

Namespaces May 18, 2011 by Christoff Truter

Hi Leo Thanks for including the needed namespaces, I didn't include it in the post, I only included the needed assemblies, I added it to the post just now.

May 18, 2011 by Leo

Curiously I had to add the following using directives, and all worked fine... using Google.YouTube; using Google.GData.YouTube; using Google.GData.Client; using Google.GData.Extensions; using Google.GData.Extensions.MediaRss;
