You can share your streams and videos to play directly in Facebook. But some links are displayed as page preview because of the local facebook cache. If the link was shared before as an image, it will shows up without player. It’s possible to reset Facebook cache manually for each URL, on this page.
Follow next steps:
- Copy a link to Facebook Sharing Debugger
- Click button “debug” then “Scrape Again”
Now you can make post with player instead of image.
