    Mozilla not much interested in implementing totalRoundTripTime.

    Harald: totalRoundTripTime is per candidate, SCTP or RTP round
    trip time is different.

    Varun: smooth RTT is on data channel so different. Would prefer
    to have both of them.

    Tim panton: both RTTs are useful. Would be good to have them
    both MTI.
    … More useful in a future where ICE API gets exposed.

    Mozilla: agreeing with responsesReceived and totalRoundTripTime
    to have the same exposure

    Proposal: let's continue discussion on GitHub

     Issue [28]#730 [29]🎞︎

    Poll: Proposal A: Define an algorithm in one spec that other
    specs can point to
    … Proposal B: Can that place be MC's exposure of
    powerEfficient?

    Proposal A has some consensus

    Proposal B does not have consensus

    Proposal: continue discussion, hoping to piggy back on
    webcodecs discussion

    Consensus in the room that the use case is good. Some concerns
    about the API shape.

    Proposal: focus discussion on track vs. source and other
    requirements (do we need to set auto pause dynamically). Then
    focus on API.
