Python: can't use CameraCaptureUI #759

Closed oxygen-dioxide closed 1 year ago

>>> from winrt.windows.media.capture import CameraCaptureUI
>>> cap=CameraCaptureUI()
Traceback (most recent call last):

RuntimeError: 不支持从 MTA 中激活单线程类

This is due to the fact that the library currently initializes itself as a multi-threaded apartment (MTA). Programs with a graphical user interface need to have a single-threaded apartment (STA). See discussion in #690.
