Android:“无法播放此视频"；媒体播放器VideoView错误1 -38 [英] Android: 'Can't play this video'; MediaPlayer & VideoView Error 1 -38

问题描述

我尝试使用以下代码播放视频.但是，在运行时出现了无法播放此视频"弹出窗口，出现了经典错误消息.我在搜索android资料并查看其他人的问题时做了尽职调查，但似乎找不到问题a)因为在文档中找不到MediaPlayer的错误代码(1，-38)和b)我的视频符合android媒体格式(h.264和MPEG-4)所需的规范.如果有人可以帮助我指出正确的方向，我将不胜感激！谢谢

I tried to play a video with the code below. However, I get the classic error of 'Can't play this video' pop-up at run time. I did my due diligence in searching the android literature and looking through other people's questions, but I can't seem to find the problem a) because no where in the documentation can I find the error code (1 ,-38) for MediaPlayer and b) my video meets the specifications required for android media formats (h.264 and MPEG-4). If anyone can help point me in the right direction I'd really appreciate it! Thanks

private void startVideo() {
    Log.v(TAG, "videoUrl = " + mVideoUrl);
    Uri uri = Uri.parse(mVideoUrl);
    mVideo = (VideoView) getView().findViewById(R.id.preview_videoView);
    MediaController mediaController = new MediaController(getActivity());
    mediaController.setAnchorView(mVideo);
    mVideo.setMediaController(mediaController);
    mVideo.setVideoURI(uri);
    mVideo.start();
}

这些是日志

推荐答案

我认为，您需要在onPrepare

mVideo.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
  public void onPrepared(MediaPlayer mp) {
    mVideo.start();
  }
});
