Chrome fires deviceReady event when cam is in use
See original GitHub issueDescription
In Firefox 66 I get a deviceErrorCode
name of “NotReadableError” if video is in use.
In Chrome 73 I do not get a deviceError
in fact i get a deviceReady
But when I try to start recording I get an error in console.
This data is captured in my local dev environment.
Steps to reproduce
On my Windows 10 (build 1803) development pc.
- I start the local windows 10 camera app and let it hold camera.
- I then proceed into my app and go to the video recording page.
- In Chrome I get a deviceReady called in my page - my page enables the start video capture button.
- When I click the start capture button get the above error in javascript console.
The error isn’t surprising, what is surprising is that I get a deviceReady. Despite reporting deviceReady I do not see the video preview it remains black.
Results
Expected
In Chrome I should receive deviceError event.
Actual
In Chrome I do receive a deviceReady
event.
It fails later in start() video capture.
Error output
This error appears in the Chrome js console when I execute start() because Chrome things I have the device due to deviceReady event.

Nice, I should be able to figure where I am at with that page and your example. Thanks so much! I’ll let you know if I learn anything else I think might be useful.
this is from '15: https://stackoverflow.com/questions/31108855/webrtc-check-if-camera-and-microphone-are-in-use-on-chrome If it’s still a bug, chrome is just lame.
I do hope the chromium devs have an open issue for this, haven’t found it yet though.
Come on, this can’t be real. 🤦♂️
