M50 recognized but not showing

[thomasjoubert]

Hi, I plugged my M50, it's recognized (the menu appears) but there is no preview available and OBS doesn't "see" it. The Canon Webcam utility has been uninstalled and doesn't show in /Library/CoreMediaIO/Plug-Ins/DAL/EOSWebcam.plugin I have CameraLive installed and the camera works with it. But I'd like to use PTPwebcam since it works with my others camera and we can't prevent a camera to be recognized, (otherwise I'd use the Canon Webcam Utility for the M50 only).

Here is the report

It seems like this kind of thing, with the properties not being enumerated properly, happens with other Canon M series cameras, too. Unfortanetly Canon's PTP support is a little opaque, and this will be hard to fix without a camera on hand for debugging.
