来自 Google Drive 的 Android Stream 视频

Question

我正在构建一个需要从 Google 驱动器流式传输视频的 Android 应用程序视频链接是这样的:https://docs.google.com/file/d/--ID--

我无法获得 rtsp，因此它无法在视频 View 中运行视频，并且它不会以 mp4 或 3gp 结尾...所以我无法那样运行它:

Intent intent = new Intent(Intent.ACTION_VIEW);intent.setDataAndType(Uri.parse("https:// docs.google.com/file/d/--ID--"),"video/mp4"); view.getContext().startActivity(intent);

我能够使用此代码在 webView 中运行视频:

webview.getSettings().setJavaScriptEnabled(true);webview.getSettings().setPluginState(WebSettings.PluginState.ON);webview.loadUrl("https:// docs.google.com/file/d/--ID--");

webview.setWebChromeClient(new WebChromeClient());

但是视频不能全屏播放也不能暂停而且卡顿...

那我该怎么办？无论如何都可以从 Google 驱动器流式传输视频

Answer 1

因为我也在尝试这个，我可以自己找到解决方案

1: 确保视频 url 是 https://drive.google.com/file/d/VIDEO-ID/preview "

2:我从上面的url下载网页内容，得到直接的视频url:

public String downloadUrl(String myurl) throws IOException {
        InputStream is = null;
        try {
            URL url = new URL(myurl);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setReadTimeout(10000);
            conn.setConnectTimeout(15000);
            conn.setRequestMethod("GET");
            conn.setDoInput(true);
            conn.connect();
            is = conn.getInputStream();
            String contentAsString = readIt(is);
            return contentAsString;
        } finally {
            if (is != null) {
                is.close();
            }
        }
    }

//从流输出中获取直接视频url

public String readIt(InputStream stream) throws IOException {
        BufferedReader reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"));
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            if (line.contains("fmt_stream_map")) {
                sb.append(line + "\n");
                break;
            }
        }
        reader.close();
        String result = decode(sb.toString());
        String[] url = result.split("\\|");
        return url[1]; 
    }

//我们需要一个函数来解码url才能正常使用

public String decode(String in) {
        String working = in;
        int index;
        index = working.indexOf("\\u");
        while (index > -1) {
            int length = working.length();
            if (index > (length - 6)) break;
            int numStart = index + 2;
            int numFinish = numStart + 4;
            String substring = working.substring(numStart, numFinish);
            int number = Integer.parseInt(substring, 16);
            String stringStart = working.substring(0, index);
            String stringEnd = working.substring(numFinish);
            working = stringStart + ((char) number) + stringEnd;
            index = working.indexOf("\\u");
        }
        return working;
    }

现在我使用这三个函数后，我可以获得一个由 readtIt(InputStream stream) 返回的直接视频 url 作为一个字符串，我可以用它来解析到 VideoView。
