From Facebook's
Embedded Video
"With the embedded video player you can easily add Facebook videos and Facebook live videos to your website. You can use any public video post by a Page or a person as video or live video source."
In the "URL of video" textbox, paste in the url of the public FB video you want to share.
Click the "Get Code" button.
For blogger add a "HTML/JavaScript" Gadget and add the step 2 code. I like to move it to the bottom.
Paste the Step 3 code in the html of your web page.
