Through MediaStreamConstraints, you can also pick the specific captured device using its deviceId, which can be derived from the enumerateDevices() method. The getUserMedia() call takes MediaStreamConstraints as an input argument, which defines the preferences and/or requirements for capture devices and captured media streams, such as camera facingMode, video resolution, and microphone volume. The getUserMedia() method is a good starting point to understand the Media Capture APIs. A brief summary of the Media Capture and Streams APIs We will also suggest some best practices when using the media capture APIs. In this blog, we will share insights on some of our implementation decisions, and share details on what we have implemented today and what we are still working on for a future release. We are very excited that major websites such as Facebook share the same vision and have adopted standards-based interfaces to enable the best user experiences across browsers. The media capture functionality in Microsoft Edge is implemented based on the W3C Media Capture and Streams specification that recently reached the Working Group “Last Call” status. Media capture functionality in Microsoft Edge To allow for early feedback from the web development community, we’ve set this feature to be “on” by default in the latest Windows Insider preview. This feature can be toggled under the experimental features interface in Microsoft Edge, which can be found by navigating to about:flags. It is known by some web developers simply as getUserMedia, which is the main interface that allows webpages to access media capture devices such as webcams and microphones. This feature is based on the Media Capture and Streams specification, developed jointly at the W3C by the Web Real-Time Communications Working Group and the Device APIs Working Group. In the latest Windows 10 preview release, we added support for media capture APIs in Microsoft Edge for the first time.
