BufferQueue已被放弃:使用TextureView播放视频时

Question

每次我暂停我的活动(实际上是碎片)去另一个应用程序,返回onResume我尝试恢复视频播放,但它不播放:我得到一个空白的屏幕.经过调查,我在Logcat中看到以下内容

E/BufferQueueProducer: [unnamed-23827-0] queueBuffer: BufferQueue has been abandoned
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/BufferQueueProducer: [unnamed-23827-0] connect(P): BufferQueue has been abandoned

这是我在简历中调用的代码

player.seekTo(mVideoSeekPosition);
player.start();

仅供参考:我一直试图将这个答案应用到我的案例中,但我不能:当BufferQueue被放弃后我该怎么办？

UPDATE

我挣扎着独自一人,但我仍在崩溃.所以我发布了整个代码以寻求帮助

我在活动之间切换时遇到了同样的问题,也有MediaPlayer(1971):错误(100,0).通过在onSurfaceTextureDestroyed中添加这些行来解决它

    @Override
    public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
        if (mediaPlayer != null) {
            mediaPlayer.stop();
            mediaPlayer.release();
            mediaPlayer = null;
        }
        return true;
    }
