Trouble Inserting VLC Instance into PyQt Frame
Posted: 18 Oct 2016 06:35
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. I'm using python-vlc, downloaded via pip.
Full disclosure, I originally posted this problem on stackoverflow, but got no response (yet).

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.
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. See full code for video_player_main_window.py here: http://pastebin.com/cHpAHZN2
