genymobile/scrcpy

Client core (app/src/scrcpy.c, main.c)

Orchestrates startup: parses CLI options, connects adb tunnel, starts the on-device server, and wires together demuxer, decoder, controller, recorder, and screen.

Media pipeline (demuxer.c, decoder.c, packet_merger.c, audio_player.c, frame_buffer.c)

Receives encoded video/audio packets from the device socket, merges fragmented packets, feeds FFmpeg decoders, and renders/plays them with clock/regulator-based synchronization.

Screen rendering (screen.c, opengl.c, texture.c, icon.c)

Manages the SDL window and OpenGL textures that display mirrored frames, including rotation, fullscreen, and resize handling.

Control/input (controller.c, input_manager.c, control_msg.c, receiver.c)

Serializes mouse/keyboard/gamepad/clipboard actions into control messages sent to the device and processes device-to-client messages.

USB/HID subsystem (usb/, hid/, uhid/, aoa_hid.c, scrcpy_otg.c)

Implements physical keyboard/mouse/gamepad simulation over USB HID/AOA/UHID and OTG-mode control without USB debugging.

ADB integration (app/src/adb/)

Locates the adb binary, lists devices, parses device state, and establishes forward/reverse socket tunnels to reach the on-device server.

scrcpy-server (server/src/main/java/com/genymobile/scrcpy)

Java process executed on the Android device via app_process that captures display/camera/audio using hidden APIs, encodes with MediaCodec/MediaRecorder, injects input events, and manages lifecycle/cleanup.

Device-side wrappers & workarounds (wrappers/, Workarounds, FakeContext, CleanUp)

Reflectively accesses hidden Android system services (WindowManager, ActivityManager, etc.), fakes a shell-UID context, applies OEM workarounds, and restores modified device settings after exit.
