I have been using Poweramp (PA) for a year+ and am  pleased  with the app. I have karaoke video files in mp4 format. When I played the mp4 file on PA through my samsung phone, i can hear the audio and be able to set the equalizer. However there is no video displayed on my phone.  How do i set to display the video?  However, the default apps on my phone for eg video player and google play music can play/display both audio/video. I intend to install PA on my android box and connect
