Implement keyboard/mouse control To control the device from the computer: - retrieve mouse and keyboard SDL events; - convert them to Android events; - serialize them; - send them on the same socket used by the video stream (but in the opposite direction); - deserialize the events on the Android side; - inject them using the InputManager.

Define feature test macros in common.h This enables necessary functions once for all. As a consequence, define common.h before any other header.

Replace SDL types by C99 standard types Scrcpy is a C11 project. Use the C99 standard types instead of the SDL-specific types: SDL_bool -> bool SintXX -> intXX_t UintXX -> uintXX_t

Rename "event" to "message" After the recent refactorings, a "control event" is not necessarily an "event" (it may be a "command"). Similarly, the unique "device event" used to send the device clipboard content is more a "reponse" to the request from the client than an "event". Rename both to "message", and rename the message types to better describe their intent.

Move event conversion to input_manager Only keep helper functions separated. This will help to convert coordinates internally when necessary.

convert_keycode_action(SDL_EventType from, enum android_keyevent_action *to);
Update code style Limit source code to 80 chars, and declare functions return type and modifiers on a separate line. This allows to avoid very long lines, and all function names are aligned. (We do this on VLC, and I like it.)

Add --prefer-text option Expose an option to configure how key/text events are forwarded to the Android device. Enabling the option avoids issues when combining multiple keys to enter special characters, but breaks the expected behavior of alpha keys in games (typically WASD).

Scale mouse events The video screen size on the client may differ from the real device screen size (e.g. the video stream may be scaled down). As a consequence, mouse events must be scaled to match the real device coordinates. For this purpose, make the client send the video screen size along with the absolute pointer location, and the server scale the location to match the real device size before injecting mouse events.
