Add missing include guards In practice, these headers are included only once, but it's a good practice to always use include guards.

Replace SDL_Atomic by stdatomic from C11 There is no reason to use SDL atomics.

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

Wait server from a separate thread Create a thread just to wait for the server process exit. This paves the way to simply wake up a blocking accept() in a portable way.

#include "config.h"
Extract server-related functions To lighten screen.c, move start_server() and stop_server() to a separate file.

#include "command.h"
Accept port range Accept a range of ports to listen to, so that it does not fail if another instance of scrcpy is currently starting. The range can be passed via the command line: scrcpy -p 27183:27186 scrcpy -p 27183 # implicitly 27183:27183, as before The default is 27183:27199. Closes #951 <https://github.com/Genymobile/scrcpy/issues/951>

#include "common.h"
Make scrcpy.h independant of other headers The header scrcpy.h is intended to be the "public" API. It should not depend on other internal headers. Therefore, declare all required structs in this header and adapt internal code.
2020-06-20 04:04:06 +08:00
#include "scrcpy.h"
Add cli option to set the verbosity level The verbosity was set either to info (in release mode) or debug (in debug mode). Add a command-line argument to change it, so that users can enable debug logs using the release: scrcpy -Vdebug

Move server-related code to server.c The file server.c already existed, but exposed a low-level API. Make it higher-level, so that scrcpy.c does not handle server details directly.

Make owned serial a pointer-to-non-const The server owns the serial, so it needs to free it. Therefore, it should not be a pointer-to-const.

atomic_flag server_socket_closed;
Kill the server only after a small delay Let the server terminate properly once all the sockets are closed. If it does not terminate (this can happen if the device is asleep), then kill it. Note: since the server process termination is detected by a flag set after waitpid() returns, there is a small chance that the process terminates (and the PID assigned to a new process) before the flag is set but before the kill() call. This race condition already existed before this commit. Fixes #1992 <https://github.com/Genymobile/scrcpy/issues/1992>

Make it work over tcpip "adb reverse" currently does not work over tcpip (i.e. on a device connected by "adb connect"): <https://issuetracker.google.com/issues/37066218> To work around the problem, if the call to "adb reverse" fails, then fallback to "adb forward", and reverse the client/server roles. Keep the "adb reverse" mode as the default because it does not involve connection retries: when using "adb forward", the client must try to connect successively until the server listens. Due to the tunnel, every connect() will succeed, so the client must attempt to read() to detect a connection failure. For this purpose, when using the "adb forward" mode, the server initially writes a dummy byte, read by the client. Fixes <https://github.com/Genymobile/scrcpy/issues/5>.

socket_t server_socket; // only used if !tunnel_forward
Use two sockets for video and control The socket used the device-to-computer direction to stream the video and the computer-to-device direction to send control events. Some features, like copy-paste from device to computer, require to send non-video data from the device to the computer. To make them possible, use two sockets: - one for streaming the video from the device to the client; - one for control/events in both directions.
