视频流与媒体播放器

标签： android video streaming video-streaming android-mediaplayer

我是新开发者，我希望我的应用能够流式传输视频。我基本上希望它像youtube一样工作，能够从自己的数据库/服务器流式传输视频（不知道它是如何工作的）。我搜索了一下从媒体播放器流式传输YouTube视频的方法，并在几个地方找到了下面的代码。 我还在xml文件中添加了一个VideoView。但它似乎有某种问题，我真的不知道它是什么。代码与我发现的唯一不同之处在于我将其修改为从片段而不是从活动中进行操作，因为现在我的应用只包含一个活动和四个三个片段。

所以我有两个问题：1。有没有人知道我的实施问题是什么？ 2.这是我与服务器交互的方式，如果我在该服务器上拥有所有视频 - 只需写入网址？感谢。

public class main_page extends Fragment {
    public main_page() {

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View rootView = inflater.inflate(R.layout.main_page, container, false);
        return rootView;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);
        VideoView videoView=(VideoView)getActivity().findViewById(R.id.vvMainPage);


        MediaController mc=new MediaController(getActivity());
        videoView.setMediaController(mc);

        String str="https://www.youtube.com/watch?v=fvEZUbzqqyM";
        Uri uri=Uri.parse(str);

        videoView.setVideoURI(uri);

        videoView.start();
        videoView.requestFocus();


    }

}

试试这个

Uri uri = Uri.parse("first_uri");
MediaController mediaController = new MediaController(this);
VideoView videoView = (VideoView) findViewById(R.id.video);

    mediaController.setAnchorView(videoView);
    videoView.setVideoURI(uri);
    videoView.setMediaController(mediaController);
    videoView.start();
