Question

我正在使用Vitamio库，需要每分钟播放一段短片。有一段时间它工作得很好，但在几次执行后，Vitamio开始显示空白屏幕而不是播放视频。 Native Video在这种情况下效果很好，但我需要支持更多的视频格式。

以下是视频显示时的Vitamio日志：

这是我的代码片段，用于启动视频：

if(mVideoView.isPlaying()) {
    mVideoView.stopPlayback();
    mVideoView.destroyDrawingCache();
}
mVideoView.setVisibility(View.VISIBLE);
mVideoView.setVideoPath(path);
mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mVideoView.setMediaController(null);
mVideoView.requestFocus();
mVideoView.start();

有没有人遇到过这样的问题？如何正确释放所有Vitamio资源并重用VideoView？这没有任何改变：

mVideoView = null;
mVideoView = (VideoView) findViewById(R.id.videoViewForAdv);

Answer 1

我找到了解决问题的方法。我刚刚将Vitamio VideoView改为Vitamio MediaPlayer。现在一切正常。以下是我播放视频的结果代码：

releaseMediaPlayer();
try {
    mMediaPlayer = new MediaPlayer(getApplicationContext());
    mMediaPlayer.setDataSource(path); //Path to video file
    mMediaPlayer.setDisplay(holder); //Set SurfaceHolder
    mMediaPlayer.prepare();
    mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
       @Override
       public void onPrepared(MediaPlayer mp) {
             startVideoPlayback();
       }
    });
}
catch (Exception e){} 

...

private void releaseMediaPlayer() {
    if (mMediaPlayer != null) {
        if(mMediaPlayer.isPlaying())
            mMediaPlayer.stop();
        mMediaPlayer.release();
        mMediaPlayer = null;
    }
}

private void startVideoPlayback() {
    holder.setSizeFromLayout();
    mMediaPlayer.start();
}

如何多次使用Vitamio VideoView？
