### Bug description

I am trying to embed videos on a book site using raw links from Dropbox. However, the video shortcode can't seem to parse the URL. For example, if a qmd document tries to include [this video file](https://www.dropbox.com/s/h3ezvnpyn8xe5ch/Section1_4_c.mp4?raw=1) using

````
Here is the video:

{{< video https://www.dropbox.com/s/h3ezvnpyn8xe5ch/Section1_4_c.mp4?raw=1 >}}
````

then rendering complains that "No video source specified for video shortcode".

This is in 1.2.280 on macos Ventura, in an empty default website template.
