OverconstrainedError.OverconstrainedError() - Web APIs

olutions if an exact match is not available, or the user overrides it. to require a capability, use the keywords min, max, or exact (a.k.a. min == max). the following demands a minimum resolution of 1280x720: { audio: true, video: { width: { min: 1280 }, height: { min: 720 } } } if no camera exists with this resolution or higher, then the returned promise will be rejected with overconstrainederror, and the user will not be prompted. the reason for the difference in behaviour is that the keywords min, max, and exact are inherently mandatory. whereas plain values and a keyword called ideal are not. here's a full example: { audio: true, video: { width: { min: 1024, ideal: 1280, max: 1920 }, height: { min: 576, ideal: 720, max: 1080 } } } an ideal value, when used, has...
