Re: How to stream live content from YouTube using QWebEngineView

Hi out there. I have been using the advice as mentioned in the link above, as I also did hit the HTML5 problem when wanting to play a YouTube live stream. It is also not working in the Qt Demo Browser example. So do not know how to resolve.

Problem:
I do not get a YouTube live stream in the window. It does continue to spin (hourglass), as if it is loading. When I slide the YouTube progress bar back I do see the historical snapshots passing by.

Question:
Who know the solution for this problem?

Set-up:

• Windows 10, 64bit
• QT version: C:\Qt\5.9.1\msvc2017_64
• Installed Flashplayer: https://get.adobe.com/flashplayer/
• C++ coding, snippets:
  webview = new QWebEngineView;
  webpage = new QWebEnginePage;
  webpage->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true);
  .....
  webpage->load(QUrl(https://www.youtube.com/embed/live_stream?channel=UCrYJITU7pDh73ovCUQ_sUPg));
  webview->setPage(webpage);
