PyQt6 and QWindowCapture

[Jason Hallen]

Wonderful, thank you! I upgraded to v6.6 and I now have access to
QWindowCapture.

However, I'm having trouble recording any windows. I must be missing
something. Here's my code where I'm trying to capture my VS Code window.

self.window_capture = QWindowCapture(self)
self.window_capture.setWindow(QWindowCapture.capturableWindows()[13])   #
VS Code window
self.window_capture.start()
self.media_capture_session = QMediaCaptureSession()
self.media_capture_session.setWindowCapture(self.window_capture)
self._video_widget = QVideoWidget(self)
self._video_widget.resize(400, 300)
self.media_capture_session.setVideoOutput(self._video_widget)

When I run this I don't see anything in the video widget. Here's a
screenshot.

When I instead use QScreenCapture in the MediaCaptureSession I see the
video feed.

Can someone help me properly connect a window capture?

Thanks,
Jason
