Playing Videos stored in Google Drive

If you want to play a GoogleDrive video in mp4 format on your HTML page, do the following:

Open your GoogleDrive and right click on the video your want to play on your HTML page.
In the menu that opens, choose 'get link'.
In the tab that opens, make your link public (= anyone who has the link can see the video) and click on 'copy link'. The copied link looks like https://drive.google.com/file/d/1KrtLp296xfwnxA3bDTajXtPOKTqDs8Cb/view?usp=sharing or something similar. The id of the video is the part in green.
Now in order to play the video using the video embed element, replace the copied link with https://drive.google.com/uc?export=download&id=1KrtLp296xfwnxA3bDTajXtPOKTqDs8Cb. (In more general terms, replace https://drive.google.com/file/d/VIDEOID/view?usp=sharing with https://drive.google.com/uc?export=download&id=VIDEOID).

So this works:
<video controls src="https://drive.google.com/uc?export=download&id=1KrtLp296xfwnxA3bDTajXtPOKTqDs8Cb "></video>

If you want to dynamically include GoogleDrive videos in your page, you can do the following:

Put this script in the head of your page.
Create a link like <a style="cursor: pointer; text-decoration: underline" onclick="create_video('https://drive.google.com/uc?export=download&id=1KrtLp296xfwnxA3bDTajXtPOKTqDs8Cb', '80%', '80%') " >Liszt: Dante Symphony</a>

A click on this link will load a centered video whose size is 80% of the window (you may adapt the size) and whose position is fixed. The script provides it with a close button. You can make as many links as you want.

IMPORTANT: If the user's browser cookie settings are 'too secure', this may not work. The script will signal this to the user whenever this is the case.
