Is there any official way of to play YouTube videos other than YouTubePlayer API. And is there any violation of policy of YouTube, if I play YouTube videos using ExoPlayer? By using YouTubePlayer API there is a limit to customize player. I want to make my own button in the player and ExoPlayer allow me to do this. Just like Ampme is not using YouTubePlayer API for playing YouTube videos. Here it says that ExoPlayer is not used for playing YouTube videos officially.
UPDATED: By exploring I found the library which is officially playing YouTube videos by using the YouTubePlayer API but the limitation is I cannot change the speed of the playback. I need to change the playback speed.
