This reverts commit 74281bed5350af9c15f83e0b1aec5c5921dbf76f. Reason for revert: Fixed unit test by removing VP9 profile 2 from encoder factory unit test since this is platform dependent. Original change's description: > Revert "Handle scalability mode in QueryCodecSupport" > > This reverts commit 715a14811883a642e3acca21fb6017f8a128c0a5. > > Reason for revert: Speculative revert. Breaks upstream project http://b/200009579 > > Original change's description: > > Handle scalability mode in QueryCodecSupport > > > > All valid scalability modes should be supported by the builtin > > software decoder/encoder. > > > > Bug: chromium:1187565 > > Change-Id: If66105d210d5055019f35dae2f80a18ad4a70cdd > > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/222642 > > Commit-Queue: Johannes Kron <kron@webrtc.org> > > Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> > > Reviewed-by: Erik Språng <sprang@webrtc.org> > > Cr-Commit-Position: refs/heads/main@{#34998} > > TBR=danilchap@webrtc.org,sprang@webrtc.org,kron@webrtc.org,webrtc-scoped@luci-project-accounts.iam.gserviceaccount.com > > Change-Id: Ibf40d523c50791d73e2afdc3917892b859d2bcb6 > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: chromium:1187565 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/232020 > Reviewed-by: Andrey Logvin <landrey@webrtc.org> > Commit-Queue: Andrey Logvin <landrey@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#35001} Bug: chromium:1187565 Change-Id: I598a2a530b8fea22997bbb5910eb3b864d1e28a2 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/232021 Reviewed-by: Erik Språng <sprang@webrtc.org> Reviewed-by: Danil Chapovalov <danilchap@webrtc.org> Commit-Queue: Johannes Kron <kron@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35003}
