C# YouTube : Google API





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...

Thanks and Async

Hey there. Thank you for posting that friendly examples. They really helped me a lot. They worked fine but my project required an async operation for the upload and luckyly I have found an other helpful example posted here: https://groups.google.com/forum/?fromgroups=#!topic/youtube-api-gdata/IbAyA8cLNWo Maybe that helps also someone else so I want to share it here beside your nice tutorial. Maybe you want to add it anyway as an optional way with progress output. Instead of: request.Upload(newVideo); Use: request.Service.InsertAsync(new Uri("http://uploads.gdata.youtube.com/feeds/api/users/default/uploads"), newVideo.AtomEntry, newVideo); request.Service.AsyncOperationProgress += new AsyncOperationProgressEventHandler(Progress); And add: public void Progress(object sender, AsyncOperationProgressEventArgs e) { MyProgressVariable = e.ProgressPercentage; }


Thank You for sharing. Was very helpful for me

You guys saved my life

I'm working on my graduation project which I have to submit in 10 days, So the last minute goal came from the lecturer and he asked me to add a button which will upload some videos that my program captures to youtube. So all day long I've been tryinig to get my piece of code working today, and I cant remember how many combinations I've tried and how many forums I have visited, And this article was the clearest one, although, I read this one like ten times at least :D, Because I was getting an error and I thought I wrote something wrong or missed some part, like username should be in e-mail format, etc. and I was like "seriously? I cant be missing anything, theres only one key and one application name in the dashboard" but finally I figured out it wasnt that. You wont believe me, I started around 6 o clock and now its 11.30, and the reason all this time I was getting error was that stupid video I been triying to upload. I changed it, and U-LA LA! works GREAT!!. So millions times of thanks to whom this article was written by.
