Adds new method VideoSendStream::SetSource(rtc::VideoSourceInterface* and VieEncoder::SetSource(rtc::VideoSourceInterface*) This is the first step needed in order for the ViEEncoder to request downscaling using rtc::VideoSinkWants instead of separately reporting CPU overuse and internally doing downscaling due to QP values This cl Revert "Revert of Replace interface VideoCapturerInput with VideoSinkInterface. (patchset #13 id:280001 of https://codereview.webrtc.org/2257413002/ )" This reverts commit 9fdbda6aa3f66ea872344c22e79b23361047cbab. and fix the problem in the original cl in video_quality_test.cc BUG=webrtc:5687 TBR=mflodman@webrtc.org Review-Url: https://codereview.webrtc.org/2348533002 Cr-Commit-Position: refs/heads/master@{#14265}
