From cd26c2a88a5d082423f6a5b5f9b0f3e5ff908b7e Mon Sep 17 00:00:00 2001 From: Sameer Vijaykar <194338+sam-vi@users.noreply.github.com> Date: Thu, 18 Apr 2024 16:28:13 +0200 Subject: [PATCH] Modify the change of selected pair algo in RTCIceTransport. This ensures that each candidate pair has a unique identity, simplifying the validation of RTCIceCandidatePair arguments to RTCIceTransport methods. --- index.html | 115 +++++++++++++++++++++++++++++------------------------ 1 file changed, 63 insertions(+), 52 deletions(-) diff --git a/index.html b/index.html index 94adcfa..e8cbd34 100644 --- a/index.html +++ b/index.html @@ -1043,58 +1043,69 @@

Modifications to existing procedures

+

+ In the steps to [=RTCIceTransport/change the selected candidate pair and state=], if the selected candidate pair was changed, modify the first step to the following: +

+
    +
  1. + Let newCandidatePair be the [= list/item =] [= list/contained =] in |this|.{{RTCIceTransport/[[CandidatePairs]]}} whose {{RTCIceCandidatePair/local}} and {{RTCIceCandidatePair/remote}} attributes respectively [= candidate match | match =] the local and remote candidates of the indicated pair if one is selected, and null otherwise. +
    2. +
+

+ The candidate match algorithm given two {{RTCIceCandidate}} |first:RTCIceCandidate| and + |second:RTCIceCandidate| is as follows: +

+
    +
  1. +

    + If |first|.{{RTCIceCandidate/candidate}} is not [= string/identical to =] |second|.{{RTCIceCandidate/candidate}}, return false. +

    +
    2. +
  2. +

    + If either (but not both) of |first|.{{RTCIceCandidate/sdpMid}} and |second|.{{RTCIceCandidate/sdpMid}} is + null, return false. +

    +
    3. +
  3. +

    + If neither of |first|.{{RTCIceCandidate/sdpMid}} and |second|.{{RTCIceCandidate/sdpMid}} is null, and |first|.{{RTCIceCandidate/sdpMid}} is not [= string/identical to =] + |second|.{{RTCIceCandidate/sdpMid}}, return false. +

    4. +
  4. +

    + If either (but not both) of |first|.{{RTCIceCandidate/sdpMLineIndex}} and |second|.{{RTCIceCandidate/sdpMLineIndex}} is + null, return false. +
