CfC: Handling of MSE Candidate Recommendation "at risk" features

The HTML Media Extensions WG is issuing a Call for Consensus to determine how to handle the "at risk" features published in the most recent MSE Candidate Recommendation [1].

This CfC proposes to remove ALL of the "at risk" features identified in [1] and they will NOT appear in the upcoming candidate Proposed Recommendation.

        The following features are at risk and may be removed:

                . The appendStream method on the sourceBuffer object and algorithm steps that are used only by it.

                . The VideoPlaybackQuality object and the HTMLVideoElement Extensions that use it.

                . The totalFrameDelay attribute on the VideoPlaybackQuality object.

                . The TrackDefault object and its related objects, attributes, methods and algorithms, including: TrackDefaultList, SourceBuffer.trackDefaults, Default track language, Default track label, and Default track kinds.
The appendStream feature is covered by ISSUE-14 [2].  The current CR text will be maintained in MSE VNext for further work and to await implementations of the Streams API and the associated parts of MSE.

The VideoPlaybackQuality and totalFrameDelay features are covered by ISSUE-69 [3].  The current CR text will NOT appear in the initial MSE VNext and will be worked on in the Web Incubator Community Group [4].

The TrackDefault feature is covered by ISSUE-136 [5].  The current CR text will be maintained in MSE VNext for further work and to await MSE implementations of this feature.

Silence will be taken to mean there is no objection, but positive responses are encouraged.  If there are no objections by Wednesday Aug 10, this resolution will carry and we will proceed with the removal of the identified at risk features as we prepare the MSE Proposed Recommendation.
