784514 - [meta] Allow editing of SDP by JS between createOffer/createAnswer and setLocal/setRemote

Status: RESOLVED FIXED

(Core :: WebRTC: Signaling, defect)

Description

[Ethan Hugg [:ehugg]]

Need to figure out what parts of SDP should be editable, how to enforce these rules and how to consume edited SDP.  Currently we fail if the SDP has been changed.

[Randell Jesup [:jesup] (needinfo me)]

We should document the restrictions and options here.  obviously they could change any part of the SDP and many changes would break the negotiation.

[Suhas]

This is a spreadsheet that tries to identify some reasoning on what can/can't be edited by JS. 
Just a note, this spreadsheet was created close to 8-9 months back and need some analysis on the contents. Nevertheless, thought it could be a good framework to start with

I expect this will get changed into a meta bug.  I'd like to have "taking deltas in the SDP" done for Firefox/Gecko 29 (which uplifts to Aurora on Jan 20th).  So I'm targeting being done with this work early in the Gecko 29 cycle: Dec 16th (a month before uplift and a week before Christmas). Dependent bugs will be filed & fixed between here and Gecko 29.  There isn't a Gecko/Mozilla 29 target milestone yet in the dropdown.  When there is, we should set it.

[First some bookkeeping: This is a meta, which typically don't prioritize.  We prioritize the dependent bugs (except at the very beginning - prior to bug breakdown).]

Ethan -- Can we close this? Or are there more dependencies to add?

[Ethan Hugg [:ehugg]]

Going to close this.  I don't think there are more dependencies to add.  Using SDP as an API surface is not particularly popular in the WG.
