This reverts commit e307d56bd7e192c354871a739bc0133d88cb5379. Reason for revert: Breaks client.webrtc.perf bots. Example failure: https://ci.chromium.org/buildbot/client.webrtc.perf/Android32%20Tests%20(L%20Nexus7.2)/8635 AttributeError: Values instance has no attribute 'yuv_directory' Original change's description: > Add option to call VMAF in compare_videos.py. > > VMAF compares videos on several metrics and produces a unified score. > > Calling it from compare_videos required passing in a path to a VMAF > directory, where there should be a C++ wrapper executable and a model. > For now, the relative paths to those are constant. > > VMAF needs to compare aligned videos in YUV format, so two videos > (ref and test) will be saved by frame_analyzer after it has aligned > them. > > Bug: webrtc:9642 > Change-Id: Idddfcf6b1b235e7f925696ffc38938fb84c4ff9e > Reviewed-on: https://webrtc-review.googlesource.com/102140 > Reviewed-by: Patrik Höglund <phoglund@webrtc.org> > Reviewed-by: Sami Kalliomäki <sakal@webrtc.org> > Commit-Queue: Paulina Hensman <phensman@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#24876} TBR=phoglund@webrtc.org,sakal@webrtc.org,phensman@webrtc.org Change-Id: I3e1dc98d7dfc0309ee2934cb3a978eecf274c477 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:9642 Reviewed-on: https://webrtc-review.googlesource.com/102561 Reviewed-by: Sami Kalliomäki <sakal@webrtc.org> Commit-Queue: Sami Kalliomäki <sakal@webrtc.org> Cr-Commit-Position: refs/heads/master@{#24883}
