Revert "Implement xHE-AAC decoding via AudioToolbox on macOS 10.15+" This reverts commit 0485d783792e8efbfed4e56da9ec1a81087d0c5e. Reason for revert: Findit (https://goo.gl/kROfz5) identified this CL at revision 0485d783792e8efbfed4e56da9ec1a81087d0c5e as the culprit for failures in the continuous build including: Sample Failed Build: https://ci.chromium.org/b/8820940100274702545 Sample Failed Step: compile If it is a false positive, please report it at https://bugs.chromium.org/p/chromium/issues/entry?status=Available&comment=Datastore+key+for+the+culprit+entity%3A+chromium.googlesource.com%2Fchromium%2Fsrc%2Frefs%2Fheads%2Fmain%2F0485d783792e8efbfed4e56da9ec1a81087d0c5e&labels=Test-Findit-Wrong&components=Tools%3ETest%3EFindIt&summary=Wrongly+blame+0485d783792e8efbfed4e56da9ec1a81087d0c5e Original change's description: > Implement xHE-AAC decoding via AudioToolbox on macOS 10.15+ > > This uses the macOS AudioConverter interface to decode xHE-AAC > streams into planar floating point.

This directory contains platform-specific sandboxing libraries. Sandboxing is a technique that can improve the security of an application by separating untrustworthy code (or code that handles untrustworthy data) and restricting its privileges and capabilities.
Each platform relies on the operating system's process primitive to isolate code into distinct security principals, and platform-specific technologies are used to implement the privilege reduction. At a high-level:
mac/
uses the Seatbelt sandbox. See the detailed design for more.linux/
uses namespaces and Seccomp-BPF. See the detailed design for more.win/
uses a combination of restricted tokens, distinct job objects, alternate desktops, and integrity levels. See the detailed design for more.Built on top of the low-level sandboxing library is the //sandbox/policy
component, which provides concrete policies and helper utilities for sandboxing specific Chromium processes and services. The core sandbox library cannot depend on the policy component.
