\youtube

When generating online documentation, embeds a YouTube video in the HTML. When generating offline documentation (.qch), adds an external link to the video with a thumbnail image. The HTML docs show a thumbnail of the video with a play button. You need to save the thumbnail in \images\extraimages\ in your project folder.

Use the following URL to open the thumbnail image in a browser: https://img.youtube.com/vi/<ID>/0.jpg. The <ID> is the ID of the video on YouTube. For example, if the URL to the video is https://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=youtu.be, the ID is dQw4w9WgXcQ. Save the image file as dQw4w9WgXcQ.jpg.

You must add the filename of the thumbnail file to \images\extraimages\extraimages.qdocconf. For example:

 {HTML.extraimages,qhp.qtdesignstudio.extraFiles} += \
     images/dQw4w9WgXcQ.jpg

To add a link to the video in text, write:

 \youtube dQw4w9WgXcQ
