如何从 HTTPS URL 获取 RTSP URL？ [关闭]

Question

如何将 HTTPS 转换为 RTSP URL。

谁能为我提供正确的代码示例解决方案？

这是我的代码：

  MediaController mc = new MediaController(MainActivity.this);
        mc.setAnchorView(videoView);
        Uri video = Uri.parse(newurl);
        videoView.setMediaController(mc);
        videoView.setVideoURI(video);

尝试以下方法。

注意：确保在任何后台线程中使用getUrlVideoRTSP 方法。使用 AsyncTask 或 Thread 执行网络操作。

public static String getUrlVideoRTSP(String urlYoutube)
{
    try
    {
        String gdy = "http://gdata.youtube.com/feeds/api/videos/";
        DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
        String id = extractYoutubeId(urlYoutube);
        URL url = new URL(gdy + id);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        Document doc = documentBuilder.parse(connection.getInputStream());
        Element el = doc.getDocumentElement();
        NodeList list = el.getElementsByTagName("media:content");///media:content
        String cursor = urlYoutube;
        for (int i = 0; i < list.getLength(); i++)
        {
            Node node = list.item(i);
            if (node != null)
            {
                NamedNodeMap nodeMap = node.getAttributes();
                HashMap<String, String> maps = new HashMap<String, String>();
                for (int j = 0; j < nodeMap.getLength(); j++)
                {
                    Attr att = (Attr) nodeMap.item(j);
                    maps.put(att.getName(), att.getValue());
                }
                if (maps.containsKey("yt:format"))
                {
                    String f = maps.get("yt:format");
                    if (maps.containsKey("url"))
                    {
                        cursor = maps.get("url");
                    }
                    if (f.equals("1"))
                        return cursor;
                }
            }
        }
        return cursor;
    }
    catch (Exception ex)
    {
        Log.e("Get Url Video RTSP Exception======>>", ex.toString());
    }
    return urlYoutube;

}

protected static String extractYoutubeId(String url) throws MalformedURLException
{
    String id = null;
    try
    {
        String query = new URL(url).getQuery();
        if (query != null)
        {
            String[] param = query.split("&");
            for (String row : param)
            {
                String[] param1 = row.split("=");
                if (param1[0].equals("v"))
                {
                    id = param1[1];
                }
            }
        }
        else
        {
            if (url.contains("embed"))
            {
                id = url.substring(url.lastIndexOf("/") + 1);
            }
        }
    }
    catch (Exception ex)
    {
        Log.e("Exception", ex.toString());
    }
    return id;
}

示例

new Thread(new Runnable() {
    @Override
    public void run() {
        String newurl = getUrlVideoRTSP("http://www.youtube.com/watch?v=9fBcrzA-hWY"));
    }
}).start();
