Webview android未正确显示来自摄像头的视频

我使用Webview使用webRTC API加载视频，它在一些设备上运行良好，但在我测试的许多其他设备上不工作。这是输出的视频。这是一个视频，而不是GIF，正如你所看到的，视频没有播放，而是被击中。

下面是webview的代码

        setUpWebViewDefaults();


 webView.loadUrl("https://mysecurewebsite.com/api/connect?video_call_id=" + mVideoCallId);

    webView.setWebChromeClient(new WebChromeClient() {
        @Override
        public boolean onConsoleMessage(ConsoleMessage consoleMessage) {
            Log.d("getUserMedia, WebView", consoleMessage.message() + " -- From line "
                    + consoleMessage.lineNumber() + " of "
                    + consoleMessage.sourceId());

            return true;
        }

        @Override
        public void onPermissionRequest(final PermissionRequest request) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // Below isn't necessary, however you might want to:
                    // 1) Check what the site is and perhaps have a blacklist
                    // 2) Have a pop up for the user to explicitly give permission
                    if(request.getOrigin().toString().equals("https://mysecurewebsite.com/") ||
                            request.getOrigin().toString().equals("https://mysecurewebsite.com/")) {
                        System.out.println("correct site");
                        request.grant(request.getResources());
                    } else {
                        System.out.println("incorrect site");
                        request.deny();
                    }
                }
            });
        }
    });

下面是setUpWebViewDefaults函数

    private void setUpWebViewDefaults() {
    WebSettings settings = webView.getSettings();
    settings.setJavaScriptEnabled(true);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
    }
    settings.setCacheMode(WebSettings.LOAD_NO_CACHE);

    settings.setAllowContentAccess(true);
    settings.setAllowFileAccessFromFileURLs(true);
    settings.setAllowUniversalAccessFromFileURLs(true);
    settings.setJavaScriptCanOpenWindowsAutomatically(true);
    settings.setMediaPlaybackRequiresUserGesture(false);

    // Enable remote debugging via chrome://inspect
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        WebView.setWebContentsDebuggingEnabled(true);
    }

    webView.clearCache(true);
    webView.clearHistory();
    webView.setWebViewClient(new WebViewClient());

}
