MS Teams crashes when EOS Webcam Utility is used for Video

Hi, 

I am using Microsoft Teams for my school. I am using EOS Webcam Utility (NOT Beta) with my Canon EOS 80D. It was working perfectly with video calls for school up until about two weeks ago. Now, whenever I turn on my camera in a video call (and the video setting is EOS Webcam), my Teams crashes and I get an error saying, "There was a glitch. Sorry for the inconvenience. Please sign in again." 

In my school, there is an expectation that my camera is on, and my computer's webcam is unusable, so I really need this fixed, and quickly.

Thank you so much for any help you can provide. 

Kane

    Hi - I tried going back to the beta version (0.9) but it did not help.

    So you re-installed 0.9. Did you uninstall the non-beta (1.1) or keep it?

    If you didn't remove the non-beta version it's still there and still can crash Teams. Check in team Settings > Device. If you see "EOS Webcam Utility" selected, quickly try to change it to the beta version (before the app crashes). (or just remove the whole driver/utility from Add or Remove Programs in the Windows control panel.) At least this how this issue is manifesting on my machine, it could be different on others.

    Hi - I tried going back to the beta version (0.9) but it did not help. I am using OBS (see earlier responses in this thread) with canon webcam utility which works for teams.

    For me all other apps work - it is just Teams that has a problem.

    It does appear that I can keep both 1.1 and .9 Beta installed at the same time. As long as I choose "EOS Webcam Utility Beta" in Settings > Device it appears to work fine in Teams.

    If you pick "EOS Webcam Utility", it'll crash in Settings and you'll have a hard time choosing a different camera as it will keep crashing after the application re-starts and you re-enter settings - but only after a few seconds. If you're fast you can try to change the camera back to one that works (the Beta entry in the last, or another camera if you have one) in that small window of time before settings crashes, but it may take several attempts.

    I assume using the camera switch button on while in a video call/meeting would be dangerous as it cycles to the next camera "source" without letting you choose. I bet it'll crash as it picks the non-beta EOS camera source. Just avoid the button I guess. Not a big deal if you only have the EOS camera as your only webcam, if you have multiple camera this could be an issue as now you can't change it during a meeting. I doubt anyone does this normally? I used to before my I got an AC adapter for my Canon, I'd switch to my built-in camera during long meetings when the DLSR ran out of battery.

    Edit: After many meetings today (hours) I can confirm that the Beta driver in Teams works when installed alongside of 1.1. I just have to be sure to never switch to the release EOS camera source while in Teams.

    Also, I noticed the camera does not need to be plugged for Teams to crash... just selecting the driver suffice to crash the application.

    Since today I have the same issue with catastrophic consequences since I use the EOS Webcam Utility  for work to call customers via Teams etc. This leads to a bad impression as we are are selliong "high tech systems" ouselves. Yesterday all was fine and the first call made Teams crash immediately. Also my USB mic was affected since it was part of the custom setup. All steps described here, I tried.

    What did not help:

    • Uninstalling and re-installing Teams
    • Changing from 32bit to 64bit version
    • Updating from EOS Wecam Utility 1.0 to 1.1

    What did help:

    • Uninstalling the EOS Webcam Utility 1.0 or 1.1 and moving back to the beta version (0.9)

    All other apps (Windows Camera, Webex, Nextcloud Talk) that I am using work fine with all versions 0.9, 1.0 and 1.1. Only Teams has issues.

    As I think that sticking to a beta version should not be a solution, it is up to Microsoft to fix this!
