Two key fixes for idb_companion on macOS 12.1+: 1. FBSimulatorVideoStream.m: Don't require hardware-accelerated encoding for JPEG - The original code unconditionally required hardware acceleration on macOS 12.1+ - JPEG encoding may not have hardware encoder support on all systems - This caused VTCompressionSessionCreate to fail with -12902 (kVTParameterErr) - Now only H.264 requires hardware acceleration; JPEG prefers but doesn't require it 2. FBXcodeConfiguration.m: Fall back to xcode-select -p for developer directory - The symlink at /var/db/xcode_select_link no longer exists on modern macOS - Now tries the symlink first, then falls back to running xcode-select -p 3. FBSimulatorControl.xcodeproj: Mark required headers as Public - FBSimulatorApplicationCommands.h and FBSimulatorFileCommands.h need to be public - Required for idb_companion to build against the framework 4. Applied fixes from upstream PRs facebook#889 and facebook#895 for compilation issues These fixes enable MJPEG video streaming at ~30 FPS without requiring the simulator window to be visible on screen.
