QWebView does not display a video

**MasterBLB** · 14th January 2015, 11:15

Hello

I've a local page which contains several video objects:

Qt Code:

Switch view

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8" />
  <title>HTML5 Video Player</title>
</head>
<body>
A message
    <div >
	<object width="400" height="400" data="big_buck_bunny.mp4" controls="0"></object>
	<object width="400" height="400" data="Robotica_720.wmv" controls="0"></object>
	<object width="400" height="400" data="ArchitectVideo_dvd.ogv" controls="0"></object>
    </div>
  </body>
</html>

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8" />
  <title>HTML5 Video Player</title>
</head>
<body>
A message
    <div >
	<object width="400" height="400" data="big_buck_bunny.mp4" controls="0"></object>
	<object width="400" height="400" data="Robotica_720.wmv" controls="0"></object>
	<object width="400" height="400" data="ArchitectVideo_dvd.ogv" controls="0"></object>
    </div>
  </body>
</html>

I have plugins enabled for my QWebView,but in it I don't see the movies but icon similar to those in browsers indicating a plugin is missing.

Can anyone give me a hint what I need to display the vids?

Qt 5.3 32bit,VS2013 with Add-on

Correct me if I'm wrong but for HTML5 you should use a <video> tag and not <object>. Otherwise you would be playing the video via a plugin.

That's true Wysota,but I did the above because <video> tag seems to not working too.

Qt Code:

Switch view

<!-- <video controls>
	<source src="ArchitectVideo_dvd.ogv" type="video/ogg">	
	</video> -->

<!-- <video controls>
	<source src="ArchitectVideo_dvd.ogv" type="video/ogg">	
	</video> -->

This is how my code was during 1st attempt to play a video in QWebView.
Also,from what I know there will be issues to play .avi files via <video> tag,and that possibility is highly demanded in my application.

You'll be having issues in playing them (and all other) with the plugin api if you don't have a working plugin too.

This works for me without problems:

Qt Code:

Switch view

#include <QtWidgets>
#include <QWebView>
 
int main(int argc, char **argv) {
  QApplication app(argc, argv);
  QWebView view;
  view.setUrl(QUrl::fromLocalFile("/tmp/vi/main.html"));
  view.show();
  return app.exec();
}

#include <QtWidgets>
#include <QWebView>

int main(int argc, char **argv) {
  QApplication app(argc, argv);
  QWebView view;
  view.setUrl(QUrl::fromLocalFile("/tmp/vi/main.html"));
  view.show();
  return app.exec();
}

html Code:

Switch view

<html>
<body>
<video width="1920" height="1080" controls>
        <source src="http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_surround.avi" type="video/mp4"/>
</video>
</body>
</html>

        <source src="http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_1080p_surround.avi" type="video/mp4"/>
</video>

Unfortunately,for me it does not.
Also,when I try to open the html in a browser (opera 12.17 and IE 11) it does not work too.

**wysota** · 14th January 2015, 13:07

Tough luck, it's valid html5 code. You should at least get the (probably black) player rectangle, even if your browser cannot play the movie. You can replace the avi with some other format and try again.

Yes,that's is - I have a player object,but nothing happens when I hit play.
And that's the result for all video types.
