ShijunS has just created a new issue for https://github.com/w3c/mediacapture-fromelement: == define behaviors of the common ConstrainablePattern Interfaces == The spec currently doesn't cover behaviors for the ConstrainablePattern Interfaces. As example, here are some questions with applyConstraints() - Whether the "frameRate" constraint can be applied to video track captured from video element and canvas (might be relevant to issue #43) - Whether apps want to capture a lower resolution video from an UHD/4k-video source, and whether the "width" and "height" constraints should be honored in that case - Whether the "channelCount" constraint should be applied for captured audio tracks. As an potential use case, we might need to convert multi-channel audio to stereo before we send it out with peerconnection. - How about other audio constraints: volume, sampleRate, and sampleSize - although it might require audio DSP operations so leading to more complexity in implementations. In case any of the common ConstrainablePattern Interfaces is irrelevant, the spec should call that out explicitly.
