Android 从 Google 驱动器流式传输视频

Android Stream video from Google drive

我正在构建一个 Android 应用程序,它需要从 Google 流式传输视频 link 就像这样:https:// docs.google.com/file/d/--ID--

我无法获取 rtsp,所以它无法 运行 videoview 中的视频,并且它不以 mp4 或 3gp 结尾...所以我不能 运行 就是这样:

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 运行 webView 中的视频:

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,不能暂停,而且很卡...

那我该怎么办?无论如何可以从 Google 驱动器

流式传输视频

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url下载网页内容,直接获取视频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();
            }
        }
    }

//直接从流输出中获取视频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,我可以通过 readtIt(InputStream stream) 得到一个直接视频 url return 作为一个字符串,我可以用它来解析 VideoView.
