I know this question has been asked many times.
I read everything on the topic. It's exactly the same problem here
I have a custom html5 video player that I'd like to use inside a facebook post, like youtube or vimeo does.
I added the correct meta tags but when I post the link of the player and click on play, I get a white screen with a "Download file" anchor.
It was suggested that this feature is on trial with youtube (and maybe vimeo or other partners)
Is it still the case or am I missing something ? Do I need an app approval from facebook ?
