Parse XPM without SDL_image We encounter some problems with SDL2_image on MSYS2 (Windows), so implement our own XPM parsing which does not depend on SDL_image. The input XPM is considered safe (it's in our source repo), so do not check XPM format errors. This implies that read_xpm() is not safe to call on any unsafe input. Although less straightforward, use SDL_CreateRGBSurfaceFrom() instead of SDL_CreateRGBSurfaceWithFormatFrom() because it is available with SDL versions older than 2.0.5.

Move screen-related code to screen.c The file scrcpy.c contains too many different things in addition to the main logic, so move the screen code to a separate file, screen.c.

// kill the server before decoder_join() to wake up the decoder
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.

Improve main() error handling Parse the command-line arguments first, and do not ignore avformat network init failure. At the end, deinit the avformat network.
