This reverts commit 3babb8af238a531cbff27951604b09bb78b762cd. Reason for revert: - Causes regressions to transceivers, see https://crbug.com/1291956 for more information, including tests to reproduce the issue. This CL is not a pure revert. While it reverts everything else, it does keep the new enum value (kProfilePredictiveHigh444). This is as to not break Chromium which already depend on it. It is not listed in the kProfilePatterns though so the enum value should never be applicable. Original change's description: > Added support for H264 YUV444 (I444) decoding. > > Added Nutanix Inc. to the AUTHORS file. > > PS#1 is a reland of "Added support for H264 YUV444 (I444) decoding." https://webrtc-review.googlesource.com/c/src/+/234540 > > Bug: chromium:1251096 > Change-Id: I99a1b1e4d8b60192ff96f92334a430240875c66c > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/235340 > Reviewed-by: Niels Moller <nisse@webrtc.org> > Reviewed-by: Ilya Nikolaevskiy <ilnik@webrtc.org> > Reviewed-by: Harald Alvestrand <hta@webrtc.org> > Commit-Queue: Harald Alvestrand <hta@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#35684} # Not skipping CQ checks because original CL landed > 1 day ago.
