Under the Hood

How it works

CGDisplayStream captures the virtual display at 60 Hz. Each frame is converted to greyscale via vImage SIMD, LZ4-delta compressed against the previous frame, and streamed over USB-TCP. On the device, a GL shader blit renders the texture at native refresh rate.

Version Pipeline Result
v0.1 SCStream → JPEG → WebSocket → Android WebView 15 FPS
v0.2 SCStream → vImage greyscale → LZ4 → TCP → Skia Canvas 20 FPS
v0.3 SCStream → vImage → LZ4 delta → TCP → GLES blit 30 FPS
v1.0 CGDisplayStream → vImage → LZ4 delta → TCP → GL shader blit 60 FPS
