youtubePlayer = YTSwiftyPlayer(
            frame: CGRect(x: 0, y: 0, width: postView.frame.size.width, height: postView.frame.size.height),
            playerVars: [
                .playsInline(true),
                .videoID(videoUrl.getVideoIDFromYoutubeUrl()),
                .loopVideo(false),
                .showRelatedVideo(false)
        ])
        youtubePlayer?.autoplay = true
        youtubePlayer?.backgroundColor = Color.videoBackground.value
        self.postView.addSubview(youtubePlayer ?? YTSwiftyPlayer())
        //youtubePlayer?.delegate = self
