VideoSendStreamInternal is created and used on the new task queue. > > - BitrateAllocator is now created on libjingle's worker thread but always used on the new task queue instead of both encoder threads and the process thread. > > - VideoEncoderConfig and VideoSendStream::Config support move semantics. > > - The encoder thread is moved from VideoSendStream to ViEEncoder. Frames are forwarded directly to ViEEncoder which is responsible for timestamping ? and encoding the frames. > > BUG=webrtc:5687 > > Committed: https://crrev.com/cc168360f41322332860cb075edeb1cde21aa473 > Cr-Commit-Position: refs/heads/master@{#13767} TBR=tommi@webrtc.org,mflodman@webrtc.org,stefan@webrtc.org,sprang@webrtc.org,pbos@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
