How to Post YouTube Video on Facebook Post?

How do I post a youtube video in a facebook post like this? ... https://www.facebook.com/photo.php?v=1388469821399312

Link isn't working for me, but if you put the url of the YouTube video in a post, it shows up.

You first go to YouTube and copy the URL of your video
Then you go here http://www.computerhope.com/issues/ch001002.htm and paste that URL to requiered field
Choose MP4 and save it to your pc
Open your FB page and click Photo/Video, then you upload a video from your PC and wait (this may take a couple of minutes or seconds, depends on video size). Once video is uploaded you will see a message saying how they need to approve the video or something.
Refresh your page and it should be there

why don't you just copy the embed code from YT, paste it in FB in the field for creating new post, once it shows up you delete the embed code and hit submit..

Download the video off youtube and then upload it to facebook. Its not rocket science
