You can create 2 threads. First for image when it is loaded then call another thread of video. Make two runnable actions and two handlers to handle that

public void onCreate(Bundle savedInstanceState) {
    ProgressDialog pd = ProgressDialog.show(this, "","Please Wait", true, false);

    Thread th = new Thread(setImage);
    th.start();

}

public Runnable setImage = new Runnable() {
    public void run() {
        //your code 
        handler.sendEmptyMessage(0);
    }
};

private Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {

        if (pd != null)
            pd.dismiss();
    }
};

On Android it's best to use AsyncTask to execute tasks in the background while still updating UI:

1. Extend the AsyncTask
2. Start the progress dialog in onPreExecute()
3. Define the background task in doInBackground(Params...)
4. Define updating of the progress dialog in onProgressUpdate(Progress...)
5. Update dialog by calling publishProgress() from doInBackground()
6. Start a new Dialog #2 in onPostExecute().
