Description: This JavaScript sample performs the following functions:<br>

<ol>

<li>It retrieves the channel name and thumbnail of the authenticated user's channel using the API's channels.list method.</li>

<li>It handles the video upload to YouTube using the resumable upload protocol.</li>

<li>It polls for the uploaded video's upload and processing status using the API's videos.list method by setting the part parameter value to status.</li>

</ol><br>

The HTML page uses JQuery, the <code>plusone.js</code> and <code>upload_video.js</code> JavaScript files, and the

<code>upload_video.css</code> file to upload a video file to YouTube.<br><br>Note that if you use this code in your own application, you must replace the value of the <code>data-clientid</code> attribute in the code for the Sign-In Button

with your project's client ID. The only valid JavaScript origin for the client ID in the sample code is

<code>http://localhost</code>. This means that you could test the sample locally, but it would not work in your

production application.
