Is it possible to limit YouTube content? In my company I would like YouTube to be used only to watch work videos and for example to prevent music videos, film previews or video games?
Not that I have seen.
There is nothing in a YouTube URL to identify the content.
Here is an example:https://www.youtube.com/watch?v=gbxk0WnTmEU
Which one is music & which one is a video?
If you have a list of specific URLs for desired work videos, then you can set up a HTTP proxy action on your HTTPS proxy to only allow those URLs and deny all other YouTube content in URL Paths.
