This is a reland of 0cbcba7ea0dced1a7f353c64d6cf91d46ccb29f9. Original change's description: > Moved congestion controller to task queue. > > The goal of this work is to make it easier to experiment with the > bandwidth estimation implementation. For this reason network control > functionality is moved from SendSideCongestionController(SSCC), > PacedSender and BitrateController to the newly created > GoogCcNetworkController which implements the newly created > NetworkControllerInterface. This allows the implementation to be > replaced at runtime in the future. > > This is the first part of a split of a larger CL, see: > https://webrtc-review.googlesource.com/c/src/+/39788/8 > For further explanations. > > Bug: webrtc:8415 > Change-Id: I770189c04cc31b313bd4e57821acff55fbcb1ad3 > Reviewed-on: https://webrtc-review.googlesource.com/43840 > Commit-Queue: Sebastian Jansson <srte@webrtc.org> > Reviewed-by: Björn Terelius <terelius@webrtc.org> > Reviewed-by: Stefan Holmer <stefan@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#21868} Bug: webrtc:8415 Change-Id: I1d1756a30deed5b421b1c91c1918a13b6bb455da Reviewed-on: https://webrtc-review.googlesource.com/48000 Reviewed-by: Stefan Holmer <stefan@webrtc.org> Commit-Queue: Sebastian Jansson <srte@webrtc.org> Cr-Commit-Position: refs/heads/master@{#21899}
