Getting two different views in single RecyclerView using Firebase in Android

Question

I have developed an application in which there are two posts

• The image post using picasso
• the Video post using Youtube Api.

I have implemented both by using RecyclerView and Firebase recyclerAdapter but the problem is that I dont know that how to differentiate both views, if I use Video view using Youtube Api it gets attached with image view and also gets copy to all of items in recyclerView, and then there is only one video playing in all items. What I want is that if I want to show an image then the item only gets image and if I want to show video then the reyclerView item only gets video without repetition. Like Instagram. I have searched many forums but did not got any help from them. please help. I am using Firebase as my database and ViewHolders are according to that.

Class file for Image and Video posts:

FirebaseRecyclerAdapter <post, postViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<post, postViewHolder>(
    post.class,
    R.layout.post_row_recycle_home,
    postViewHolder.class,
    mDatabaseReference
) {
    @Override
    protected void populateViewHolder(postViewHolder viewHolder, post model, int position) {
        viewHolder.setimage(getApplicationContext(), model.getImage());
        viewHolder.setYoutube(model.getYoutube()); 
    }
};

mrecyclerView.setAdapter(firebaseRecyclerAdapter);

Holder:

public static class postViewHolder extends RecyclerViewPager.ViewHolder{

    View mView;

    public postViewHolder(View itemView) {
        super(itemView);
        mView = itemView;
    }

    public void setYoutube(final String youtube){
        final YouTubePlayerView youPlay = (YouTubePlayerView) mView.findViewById(R.id.youtuber);
        youPlay.initialize("SOME KEY",
            new YouTubePlayer.OnInitializedListener() {
                @Override
                public void onInitializationSuccess(YouTubePlayer.Provider provider,
                                                    YouTubePlayer youTubePlayer, boolean b) {

                    youTubePlayer.cueVideo(youtube);
                }
                @Override
                public void onInitializationFailure(YouTubePlayer.Provider provider,
                                                    YouTubeInitializationResult youTubeInitializationResult) {

            }
        });
    }

    public void setimage(final Context ctx, final String image){
        final ImageView post_image = (ImageView)mView.findViewById(R.id.post_image);

         Picasso.with(ctx).load(image)
            .networkPolicy(NetworkPolicy.OFFLINE).into(post_image, new Callback() {

            @Override
            public void onSuccess() {
            }
            @Override
            public void onError() {
                Picasso.with(ctx).load(image).into(post_image);
            }
        });
    }
}
