Troubleshooting a Canon DSLR via USB

Troubleshooting using your Canon DSLR as a webcam over USB.

Updated over a week ago

Using a Canon DSLR for your Ecamm Live broadcast is a great way to have a professional looking stream. 

Be sure to read Intro to Using Canon DSLRs with Ecamm Live first for important setup steps.

Still having trouble? Here's some troubleshooting steps:

First, always make sure your Ecamm Live is up to date: Choose Check for Updates from Ecamm Live menu.

Camera NOT showing up in Ecamm Live in the Camera menu on the menubar:

Turn off Wifi and NFC

Some Canon models have Wi-Fi or Wi-Fi and NFC wireless connections. These must be disabled in the camera’s on-screen settings to allow Ecamm Live to receive video from your camera.

Put Your Camera in Picture Mode

Ensure that your Canon is set to the normal mode that you’d use to take photos. There isn’t any need to put it in video capture mode or playback mode.
Try the P mode on the dial.

Try a Different USB Cable

Some USB cables are "charge only" and won't let the data through. Try a different USB cable, preferably one that came with the camera.

Check Catalina Security Permissions

The first time you connected the camera and opened Ecamm, Catalina asks for permission to access Photos and Removable Volumes. You must accept these permissions to allow camera access over USB.

 If you denied these permissions by accident, you can reset them in the Privacy Preferences.

Remove Memory Card

Take the SD or CF card out of your camera before each time you use it for streaming. Put it somewhere safe so you don't lose it!

Connect Your Camera Directly to the Mac

If possible, connect the USB cable directly to your Mac. Connections through USB hubs may not connect or be reliable for high-bandwidth devices, such as cameras. Other high bandwidth devices like webcams and microphones can also cause a drain on the bandwidth available to the Canon.

Set Canon EOS Utility To Not Start Automatically

The Canon EOS Utility should not be running along with Ecamm Live. There is a setting in the Canon EOS Utility menubar item to tell it to not start when a camera is connected.

You should select this option.

Camera Starts But Then Freezes

Check USB Cable Connection

Make sure the USB cable is not wiggling around in the socket on the camera. Sometimes micro-USB cables can be loose.

Set to Movie Mode

On some cameras, including the Canon M50, having the dial in Movie mode works better.

Open the View Finder

When using the M50, Canon recommends opening the folding view finder, and making sure it's pointed backwards to towards the user.

Unplug, and Power Cycle the Camera

Try turning off the camera, and unplugging the USB, re-plugging it and then plugging it back in.
