VideoView не поддерживает вращение видео, даже если матрица композиции установлена правильно и используется атрибут вращения.
Что вы можете сделать, это использовать TextureView и установить его атрибут вращение = "90" (например). Затем он будет вращать кадры, но соотношение сторон - это то, что вам нужно для себя. Для этого вы можете использовать textureView.setScaleX ((screenHeight * 1.0f) / screenWidth)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextureView
android:id="@+id/playback_video"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:rotation="90" />
</RelativeLayout>
Он также должен обрабатывать потоковое видео. Но, пожалуйста, подумайте об этом как о примере, а не о выпуске готового кода. Я переименовал некоторые вещи и удалил другие, они не имеют отношения к вопросу, и это может что-то сломать, но в целом это работоспособный пример.

Надеюсь, это поможет. Я долго искал это решение. Перепробовал почти все, и это, кажется, единственный способ.
