每次我暂停我的 Activity(实际上是 Fragment)以转到另一个应用程序时，在使用 onResume 返回时我尝试恢复视频播放但它不播放:我得到一个空白屏幕。经调查，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();

仅供引用:我一直在尝试将此答案应用于我的案例，但我不能:What can I do when the BufferQueue has been abandoned?

更新

我努力一个人去做，但我还是崩溃了。所以我发布了整个代码以寻求帮助

private void setupVideoPlayingSystem(View root) {
  textureView = (TextureView) root.findViewById(R.id.textureView);
    
  textureView.setSurfaceTextureListener(this);
}
    
    
    

@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
  Log.d(TAG, "onSurfaceTextureAvailable");
  if (null == surface) {
    Log.d(TAG, "new surface");
    surface = new Surface(surfaceTexture);
    mediaPlayer = new MediaPlayer();
    mediaPlayer.setSurface(surface);
    mediaPlayer.setLooping(false);
  }
    
  /*
    
  outstandingVideoRequest is IOU for orentation change (verifed: onResume before onSurfaceTextureAvailable)
  but for cold startup, must check mVideoUrl
  */
    
  if (outstandingVideoRequest && null != mVideoUrl) {
    
    outstandingVideoRequest = false;

        playNewVideo(mVideoUrl);
  }
    
}

最佳答案

我在 Activity 之间切换时遇到了同样的问题，还有 MediaPlayer(1971): Error (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;
    }

关于android - BufferQueue 已被放弃 : When playing video with TextureView，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33288303/
