aboba has just created a new issue for https://github.com/w3c/webrtc-extensions: == setParameters: changing scaleResolutionDownBy == The current text relating to `scaleResolutionDownBy` does not provide much detail about what happens when the value is changed in `setParameters()`. For example: - Is a keyframe automatically generated on a change to `scaleResolutionDownBy`? - If not, what happens if the decoder doesn't support the ability to do spatial prediction, that is, using frames of a resolution different than the current resolution as dependencies? Note: the Media Capabilities API makes it possible to discover whether a decoder supports spatial prediction via the [`spatialScalability`](https://w3c.github.io/media-capabilities/#dom-videoconfiguration-spatialscalability) attribute. This was needed because some (hardware) decoders were found to be unable to do spatial prediction, and therefore would produce a decoder error on encountering an encoding using spatial prediction.
