Now we always process |rate_profile.num_frames| number of frames. This means that the output of the tests in videoprocessor_integrationtest.cc will be slightly different, as we will no process 300 frames, instead of 299. No rate control or quality thresholds need to be updated, however. BUG=webrtc:6634 Review-Url: https://codereview.webrtc.org/3004583002 Cr-Commit-Position: refs/heads/master@{#19515}
