Hello TAG!

I'm requesting a TAG review of WebRTC Insertable Streams.

WebRTC Insertable Streams is a proposed API that allows the insertion of user-defined processing steps in the pipeline that handles media in a WebRTC context. It defines a number of extensions to objects defined in WEBRTC-PC, and it draws upon some definitions originally proposed for WEB-CODECS.

• Explainer¹: https://github.com/w3c/webrtc-insertable-streams/blob/master/explainer.md

• Specification URL: https://htmlpreview.github.io/?https://github.com/w3c/webrtc-insertable-streams/blob/master/index.html

• Tests:

  • https://github.com/web-platform-tests/wpt/tree/master/webrtc-insertable-streams
  • https://source.chromium.org/search?q=third_party%2Fblink%2Fweb_tests%2Ffast%2Fpeerconnection%2FRTCPeerConnection-insertable-streams*&sq=

• Security and Privacy self-review²: https://github.com/w3c/webrtc-insertable-streams/blob/master/tag_sp_questionnaire.md

• GitHub repo (if you prefer feedback filed there): https://github.com/w3c/webrtc-insertable-streams (we don't require the feedback there)

• Primary contacts (and their relationship to the specification):

  • Guido Urdaneta, (@guidou), Google, Chromium implementer, editor (guidou@chromium.org)
  • Harald Alvestrand, (@alvestrand), Google, Chromium implementer, editor (guidou@chromium.org)

• Organization(s)/project(s) driving the specification: Chromium & W3C WebRTC WG

• Key pieces of existing multi-stakeholder review or discussion of this specification: WebRTC WG Minutes, Github Issues

• External status/issue trackers for this specification (publicly visible, e.g. Chrome Status): Chrome Status, Github

Further details:

• I have reviewed the TAG's API Design Principles
• The group where the work on this specification is currently being done: W3C WebRTC Working Group
• The group where standardization of this work is intended to be done (if current group is a community group or other incubation venue): W3C WebRTC Working Group
• Major unresolved issues with or opposition to this specification: None for the API itself, but more work needed for future modules (e.g., end-to-end encryption module, support for raw media frames) to better support use cases.
• This work is being funded by: Google

We'd prefer the TAG provide feedback as (please delete all but the desired option): 💬 leave review feedback as a comment in this issue and @-notify @guidou and @alvestrand
