Build a multiplexed QUIC transport layer using Apple's Network.framework for remote desktop streaming. Covers reliable streams for control, unreliable datagrams for video, fragmentation, and latency measurement.
How to build a high-performance screen capture pipeline using Apple's ScreenCaptureKit framework — the same API used by Astropad Workbench. Covers discovery, filtering, configuration, IOSurface zero-copy, and frame status handling.
A comprehensive reverse engineering analysis of Astropad Workbench (codename Stargate), revealing the internal architecture of the LIQUID protocol — a Rust-based tile rendering engine using QUIC transport, GPU-accelerated diffing, and adaptive H.264/HEVC encoding.
