Google chrome DOMException: Permission denied by system for navigator.mediaDevices.getUserMedia

发布于 2019-11-22 19:26:47

It's November of 2019, this JavaScript code works in FireFox (70.0.1 (64-bit)), Safari (13.0.2 (15608.2.30.1.1)), Opera (Version:65.0.3467.48), On a Windows Chrome Version 70.0.3538.77 (64-bit), this code works. but NOT in MacOS Google Chrome (Version 78.0.3904.108 (Official Build) (64-bit)):

navigator
.mediaDevices
.getUserMedia({video: true, audio: true})
.then(stream => {
    console.log("success!")
})
.catch(e => {
    console.log("e: ", e);
});

In Chrome's console, I got: DOMException: Permission denied After much googling, I haven't found anything up to date. How exactly do we use JS to request camera access in Chrome?

Since MacOS Mojave, camera and microphone require OS permissions.

This applies to all non-Apple products, including all browsers other than Safari.

Check System Preferences > Security & Privacy > Privacy > Camera & Microphone. Make sure Chrome is listed and has a checkbox.

You should have gotten a special OS prompt about this the first time Chrome tried to access them. But if it accidentally got blocked somehow, you won't ever be prompted again.
