I'm checking threads here if there is a discussion that mentioned that we can post a video link here and the link will play the video but there is none.
It's good that we can post a live video here not just a link to the video but we can watch the video within the post, this will encourage members to promote their videos or post videos that are related to the discussion.
Yes, we can integrate a Youtube video into our chart like we can insert a script or code snippet-like structure in writing blogs. For example, we can insert the youtube link snippet and hit enter on LinkedIn or on the Medium platform. There are many other free platforms where we can public articles and can integrate a YouTube link in that article. Which proves to be very helpful.
To be honest, I don't see the purpose of this post, are you trying to let others know that we have this feature here, but I don't see any good use of it, while we could have only given the link also. But these Youtube snippets do save us a lot of time and energy the CPU as well, but posting more videos might increase the crime rate like spamming of posts, activity or karma, etc. That's why I prefer that less videos should be uploaded here.
