Very lightweight helper class to resize the video in texture view to fit center or crop center

Because TextureView doesn't support with video scaling like the ExoPlayer library and many develop still use TextureView to display the video. This library already provided the code for video scaling, so you don't need to write that boilerplate code anymore. Just use this library

Maven

<dependency>
 <groupId>com.akexorcist</groupId>
 <artifactId>textureviewvideoscaler</artifactId>
 <version>0.9.9</version>
</dependency>

Gradle

compile 'com.akexorcist:textureviewvideoscaler:0.9.9'

When you want to do the video scaling in your TextureView, just call the getVideoScaleMatrix(...) method

float viewWidth = ...TextureView's width...
float viewHeight = ...TextureView's height...
float videoWidth = ...Video's width...
float videoHeight = ...Video's height...
//int scaleType = VideoScaler.FILL;
//int scaleType = VideoScaler.CROP_CENTER;
int scaleType = VideoScaler.FIT_CENTER;
Matrix matrix = VideoScaler.getVideoScaleMatrix(viewWidth, viewHeight, videoWidth, videoHeight, scaleType);
textureView.setTransform(matrix);

This static method will result the result as Matrix class that you can set directly to TextureView (or customize something in Matrix class before use it)
