depending on the properties of the video, you can differentiate :

@Override Public voidOnvideosizechanged (MediaPlayer MP,intWidthintheight) {            if(Width = =0|| Height = =0) {log.e (TAG,"Invalid video width ("+ width +") or height ("+Height+")"); return; } logger.d (TAG,"onvideosizechanged Width:"+ width +"Height:"+height); Misvideosizeknown=true; Mvideoheight=height; Mvideowidth=width; intWID =mmediaplayer.getvideowidth (); intHIG =mmediaplayer.getvideoheight (); //Adjust the mode of display based on the properties of the video            if(Wid >hig) {                if(Getrequestedorientation ()! =Activityinfo.screen_orientation_landscape)                {setrequestedorientation (Activityinfo.screen_orientation_landscape); }            } Else {                if(Getrequestedorientation ()! =activityinfo.screen_orientation_portrait)                {setrequestedorientation (activityinfo.screen_orientation_portrait); }} displaymetrics DM=NewDisplaymetrics ();            Getwindowmanager (). Getdefaultdisplay (). Getmetrics (DM); Msurfaceviewwidth=Dm.widthpixels; Msurfaceviewheight=Dm.heightpixels; if(Width >height) {                //Vertical screen recording of the video, adjust its upper and lower spare                intw = msurfaceviewheight * Width/height; intmargin = (msurfaceviewwidth-w)/2; LOGGER.D (TAG,"margin:"+margin); Relativelayout.layoutparams LP=NewRelativelayout.layoutparams (RelativeLayout.LayoutParams.MATCH_PARENT,                RelativeLayout.LayoutParams.MATCH_PARENT); Lp.setmargins (Margin,0, margin,0);            MSURFACEVIEW.SETLAYOUTPARAMS (LP); } Else {                //horizontal screen recording of the video, adjust its left and right to the spare                intH = msurfaceviewwidth * Height/width; intmargin = (msurfaceviewheight-h)/2; LOGGER.D (TAG,"margin:"+margin); Relativelayout.layoutparams LP=NewRelativelayout.layoutparams (RelativeLayout.LayoutParams.MATCH_PARENT,                RelativeLayout.LayoutParams.MATCH_PARENT); Lp.setmargins (0, margin,0, margin);            MSURFACEVIEW.SETLAYOUTPARAMS (LP); }        }
