You can easily achieve this effect by putting TextureView inside CardView (from the support library).

Then you can set the radius and shadow on the CardView:

<androidx.cardview.widget.CardView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:cardCornerRadius="12dp">

    <TextureView
        android:id="@+id/video"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</androidx.cardview.widget.CardView>
