Android 4.4+中的视频呈现问题

Question

Android 4.4及以上花费太多时间在启动画面上呈现视频。

这是播放视频的方法。

private void playVideo() {
        mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

            @Override
            public void onPrepared(MediaPlayer mp) {
                mVideoView.requestFocus();
                mVideoView.start();
            }
        });
        mVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

            @Override
            public void onCompletion(MediaPlayer vmp) {

            }
        });
        String uriPath = "android.resource://" + getPackageName() + "/" + R.raw.animation_converted;
        Uri uri = Uri.parse(uriPath);
        mVideoView.setVideoURI(uri);
        if (mStopPosition != 0)
            mVideoView.seekTo(mStopPosition);
    }
}

告诉我我的错误或给我任何建议。
