How to insert VLC instance into a QFrame
<p>I'm trying to make a simple video player app by embedding a VLC instance inside a PyQt widget (a QFrame). I found a few examples that go me going, but my code doesn't quite work. When I launch it, it  plays "test_video.mp4", but it launches the regular VLC player app in its own, separate window. When I close out of the VLC player window, obviously the video stops, but the audio continues playing until I close my own Qt (PyQt) window.</p>

<p>edit 1: Forgot to mention I am using python-vlc, downloaded via pip.</p>

<pre><code>    ### video_player.py

    import sys
    import vlc
    from PyQt4 import QtCore, QtGui
    from video_player_main_window import Ui_MainWindow

    class StartQT4(QtGui.QMainWindow):
        def __init__(self, parent=None):
            QtGui.QWidget.__init__(self, parent)
            self.ui = Ui_MainWindow()
            self.ui.setupUi(self)

            self.vlc_instance = vlc.Instance("--no-xlib --sout-all")
            self.mediaplayer = self.vlc_instance.media_player_new()
            self.mediaplayer.set_xwindow(self.ui.video_frame.winId())
            print(self.ui.video_frame.winId())
            self.media_path = "test_video.mp4"
            self.media = self.vlc_instance.media_new(self.media_path)
            self.mediaplayer = self.vlc_instance.media_player_new()
            self.mediaplayer.set_media(self.media)
            self.mediaplayer.play()

    if __name__ == "__main__":
        app = QtGui.QApplication(sys.argv)
        myapp = StartQT4()
        myapp.show()
        sys.exit(app.exec_())
</code></pre>

<p>I added a "print(self.ui.video_frame.win())" just for debugging / sanity check to make sure that was a legitimate value. Command line output below. The "X server failure" shows up after I close the VLC window while my PyQt window is still running.</p>

</code></pre>

<p>The "video_player_main_window" is the module that QtDesigner (+ pyuic4) generates. "video_frame" is the name of the QFrame object I'm trying to put the VLC instance into.
