Matrix scale video on TextureView Android -

-

i'm trying play video exoplaye on textureview. in order scale , crop video fit view use matrix. custom view extends `textureview' here code:

@override public void onvideosizechanged(int width, int height, float pixelwidthheightratio) {     updatetextureviewsize(width, height);     log.v("exo", "onvideosizechanged() " +  width + "x" + height); }  private void updatetextureviewsize(float videowidth, float videoheight) {     float viewwidth = getwidth();     float viewheight = getheight();      float scalex = 1.0f;     float scaley = 1.0f;      float viewratio = viewwidth / viewheight;     float videoratio = videowidth / videoheight;     if (viewratio > videoratio) {         // video higher view         scaley = videoheight / videowidth;     } else {         //video wider view         scalex = videowidth / videoheight;     }      matrix matrix = new matrix();     matrix.setscale(scalex, scaley, viewwidth / 2, viewheight / 2);       settransform(matrix); }

i had rectangular views , worked perfectly. views have 2 states: expanded (the old ones still rectangular) , collapsed (have smaller height.

so video stretched vertically in collapsed views.

for instance have view 1080x480 , video 360x640 looks video scaled , cropped 1080x1080 , stretched 1080x480.

what doing wrong here ?

upd: here screenshots: enter image description here

check updatetextureviewsize :

i'm using unity3d networked multiplayer online game have large complex 3d terrain scene forest, trees, cliff, hills, mountains, bounders, etc. players can build structures sort of minecraft, , put them anywhere in scene, or move them around anytime. aside human controlled players, there automated ai players , objects animals roaming around scene following path. the problem how make these automated ai players , animals, able navigate around static , dynamic player created structures, because path follow can blocked player created structures, or other players , other ai objects, cliffs etc. have find away around them or on track if tumble down off high cliff example. so made navmesh , used navagents, takes care of static, non moving objects, how make ai players navigate around each other , dynamic structures created players can number in hundreds? i thought of adding navmeshobstacle everything, result in being attached hundreds of objects since user created structures b...
