VideoView不播放。还听不到声音

Question

在Kotlin / Android 我正在尝试播放mp4视频 Logcat显示这些错误

example.so: population.o example.o neat.o network.o nnode.o link.o trait.o gene.o innovation.o organism.o species.o genome.o

没有视频，尽管出现错误消息，您仍然可以听到音频。

和

<VideoView
            android:id="@+id/exercise_video"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginStart="10dp"
            android:layout_marginTop="5dp"
            android:layout_marginEnd="10dp"
            android:layout_marginBottom="5dp"
            android:visibility="gone"
            android:background="@android:color/holo_green_dark"
            android:contentDescription="@string/blank" />

我尝试了其他网址，但都遇到相同的问题

什么是IOException或SecurityException？

预先感谢
