Capture multiple cameras simultaneously with getUserMedia

[guest271314]

Is there a technical reason that multiple cameras cannot be captured with one or more call to getUserMedia({video: true}) and getUserMedia({video: {deviceId: {exact: deviceId}}})?

I read this https://superuser.com/questions/431759/using-multiple-usb-webcams-in-linux used different USB ports instead of the previous test with multiple cameras on one USB hub set width and height constraints to 320 and 240 after getUserMedia() and was able to simultaneously capture both cameras. This does not appear to be an issue with getUserMedia().

You can capture multiple cameras with multiple getusermedia calls indeed.

On Linux, not when the cameras are connected to the same USB hub and the width and height exceed 320x240. "The requested device not found" or "Could not start device" error will be thrown.
