Android application can't launch some videos from YouTube

I try to play video from YouTube in the application. Some videos are launching, but for some I get an error 'Video is not available'!I have no idea what is the difference!

My code:

    mOnInitializedListener = new YouTubePlayer.OnInitializedListener() {            @Override            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {                Log.d(TAG, "onClick: Done initializing");                //youTubePlayer.loadVideo("G5ws-ztZ0xU"); // <-- this is working!                 youTubePlayer.loadVideo("K0PtPOtMCy4&t=9s"); // <-- this is not working!            }
