getUserMedia should not ask for permissions if constraints cannot be satisfied |
||
Issue descriptionChrome asks for permission if getUserMedia is invoked with constraints that cannot be satisfied. This contradicts the spec. See steps 6.2.1 and 6.2.3 of https://w3c.github.io/mediacapture-main/#dom-mediadevices-getusermedia However, some applications rely on the nonstandard behavior. See Issue 690336 .
