With the COVID-19 lockdown, I needed to do some videoconferencing with zoom.us, but I wanted something higher quality than my MacBook’s built-in webcam. So instead I wanted to use my Canon 5D III. (These instructions are for macOS only, not Windows)
First we need to export your camera’s proprietary liveview into a video stream we can use. To do this you can install v002-Camera-Live:
Turn on your camera and connect it to your computer with USB, then run Camera Live and double click your camera in the list to activate it. This makes the liveview output from your Canon camera available as a Syphon video stream.
But zoom.us doesn’t support Syphon video directly, it only supports webcams. So you now need to convert the Syphon stream into a virtual webcam using CamTwist Studio:
In CamTwist’s menu, go into Preferences and change the resolution to 1280×720 and the framerate to 25 fps, then quit CamTwist and reopen it. Double click “Syphon” in the left pane, then on the right pane select “Camera Live” as your source. Now in the menu bar, click View -> Preview, and you should see a small preview window from your Canon camera:
If your camera falls asleep, you will need to half-press its shutter to wake it back up and reselect the Camera Live stream in the right pane.
Now your Canon camera will appear as a webcam in Chrome’s settings, at least in Chrome version 81, so you’ll be able to use it with various webapps. But it will not be available in the Zoom.us app’s video settings if you’re using Mojave or Catalina. This is because Zoom is running in a high security mode that prevents CamTwist’s extension from being loaded into it.
To fix this you need to codesign the zoom.us app to add an entitlement which allows it to load libraries from third-party authors. Quit Zoom if it is already running.
First, create a codesigning identity for yourself:
- Open the “Keychain Access” app
- In the main menu select Keychain Access -> Certificate Assistant -> Create a certificate…
- Call it “my-zoom”, set identity type to “self-signed root”, and certificate type to “code signing”
- Click Create, and continue to finish the wizard
Now run these commands in the Terminal to make a new copy of the zoom.us app on your desktop and export its current entitlements to a file:
Open up the
entitlements.plist file that is created on your desktop in TextEdit to add these two lines before the closing
The end result should look like this:
Now back in the Terminal, you can use that new entitlements file to re-sign Zoom:
Now you have a fixed version of Zoom on your desktop ready to use! You can either move it into your Applications folder to replace the original one, or keep it on the desktop. You may need to right-click on it and click “Open” to run it instead of double-clicking on it. Now if you enter Zoom’s preferences, you should find CamTwist as a choosable camera and everything will work nicely:
Note that you’ll likely need to repeat this codesigning when Zoom is updated.
