This is a reland of commit 92043022488f80fd58c91d4dbb6889248de160ce Original change's description: > Implement Optimized CropAndScale for ObjCFrameBuffer > > The default implementation of CropAndScale uses ToI420() and then Scale, > and this implementation behaves inefficiently with RTCCVPixelBuffer. > > Bug: None > Change-Id: I422ef80d124db0354a2e696892e882a78db445bb > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/271140 > Reviewed-by: Kári Helgason <kthelgason@webrtc.org> > Commit-Queue: Daniel.L (Byoungchan) Lee <daniel.l@hpcnt.com> > Auto-Submit: Daniel.L (Byoungchan) Lee <daniel.l@hpcnt.com> > Commit-Queue: Kári Helgason <kthelgason@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#37877} Bug: None Change-Id: Ie74146a33c1f54d0c988978bd925671afe699d05 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/272740 Reviewed-by: Kári Helgason <kthelgason@webrtc.org> Commit-Queue: Daniel.L (Byoungchan) Lee <daniel.l@hpcnt.com> Cr-Commit-Position: refs/heads/main@{#37887}
