if Pakistan ISP's are blocking youtube, there's not much you can do. There are probably ways to unblock it, like using an intermediate server (on which youtube isn't blocked) and streaming it back to the client that is trying to watch the video, but that would probably be considered illegal.
If you still want to make your video's available to your users, I think your best solution would be to upload your video to some other kind of social media (facebook?) that isn't blocked and share them through an embedded link. Or upload your video's to your webserver and use the HTML5 video tag to make your video's viewable on your website.
