8b235dbb0f829b9d9fe869af9615b3f7464511ee Implement a VideoToolbox H264 encoder in WebCore
not a security fix
confidence 0.08
signal score 7.9
Source/WebCore/Headers.cmake
Classified as not security-relevant.
Triage note: Adds H264Utilities.cpp (libwebrtc-ported SPS/PPS/slice bitstream parser with bounds checks), GPUVideoEncoderVTBH264, and many kVTProfileLevel_H264_* soft-link constants. New H264 encode path; brand-new code, not a fix.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
