(patchset #8 id:140001 of https://codereview.webrtc.org/1413713003/ ) Relanding after fixing CallAndModifyStream to account for new procedures for adding/removing a track from a stream. Original issue's description: > Adding the ability to create an RtpSender without a track. > > This CL also changes AddStream to immediately create a sender, rather > than waiting until the track is seen in SDP. And the PeerConnection now > builds the list of "send streams" from the list of senders, rather than > the collection of local media streams. > > Committed: https://crrev.com/ac9d92ccbe2b29590c53f702e11dc625820480d5 > Cr-Commit-Position: refs/heads/master@{#10414} Review URL: https://codereview.webrtc.org/1468113002 Cr-Commit-Position: refs/heads/master@{#10790}
