Center Crop an Android VideoView

Question

I am looking for something like the CENTER_CROP in ImageView.ScaleType

Scale the image uniformly (maintain the image\'s aspect ratio) so that both dim

Answer 1

You can only achieve this with a TextureView. (surfaceView won't work either). Here's a lib for playing video in a textureView with center crop function. TextureView can only be used in api level 14 and up unfortunately.

Another possibility is to zoom in the videoview just right, but I haven't tried that yet.

Answer 2

Nabin's answer worked for me.

Here is the Java version:

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        float videoRatio = mp.getVideoWidth() / (float) mp.getVideoHeight();
        float screenRatio = videoView.getWidth() / (float) videoView.getHeight();
        float scaleX = videoRatio / screenRatio;
        if (scaleX >= 1f) {
            videoView.setScaleX(scaleX);
        } else {
            videoView.setScaleY(1f / scaleX);
        }
    }
});

Answer 3

//store the SurfaceTexture to set surface for MediaPlayer
mTextureView.setSurfaceTextureListener(new SurfaceTextureListener() {
@Override
    public void onSurfaceTextureAvailable(SurfaceTexture surface,
            int width, int height) {
        FullScreenActivity.this.mSurface = surface;

    }

Answer 4

The simple and easy way if you are using ConstraintLayout.

XML

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

    <VideoView
        android:id="@+id/videoView"
        android:layout_width="@dimen/dimen_0dp"
        android:layout_height="@dimen/dimen_0dp"
        android:visibility="gone"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

then

In Kotlin:

videoView.setOnPreparedListener { mediaPlayer ->
    val videoRatio = mediaPlayer.videoWidth / mediaPlayer.videoHeight.toFloat()
    val screenRatio = videoView.width / videoView.height.toFloat()
    val scaleX = videoRatio / screenRatio
    if (scaleX >= 1f) {
        videoView.scaleX = scaleX
    } else {
        videoView.scaleY = 1f / scaleX
    }
}

And this worked for me.
