This is a simple Qt-based widget for monitoring a camera on the network, and performing some overdrawing of the images. It is still subject to change and also involves at least one developer translating years of C++ Qt experience into Python and qtpy.
It depends upon qtpy which needs PySide2 or PyQt5 in order to show anything.
This currently expects a network endpoint that offers a single JPEG file, which it will use to download from periodically. Things like the FFMPEG plugin for the area detector and the AXIS webcams support this. Likely soon I will add support for the MJPEG stream that is offered by some of the cameras for more efficient data streaming from the cameras.
