As you can see in top picture, the video is in 18:9 aspect ratio because by default exoplayer adjust video scale to my device screen, I want to disable it to play video content in 16:9 ratio aspect but I don't know to do that, I edited exoplayer files but nothing works.
Exoplayer is already added in app, I want to know what is the exoplayer XML file that control video scale and what I need to edit to get default video scale?
