Win10 compiles ffmpeg (including ffplay)

1、 install MSYS2

       Win10 build MSYS2 Environmental Science _cloud_yq The blog of -CSDN Blog

2、 compile SDL

        SDL It's compilation generation ffplay The basis of , You don't have to generate ffplay Do not compile SDL.

        1） Download address ：https://www.libsdl.org/download-2.0.php

        2） As a result of MSYS2 Compile below , download SDL2-2.0.22.tar.gz - GPG signed This package .

        3） Compilation steps

              step1、mkdir /usr/local/SDL2    This path is used to store SDL Compiled file , It can be changed （ After the change, other subsequent places should also be modified synchronously ）

              step2、./configure --prefix=$MSYS2/usr/local/SDL2/    here $MSYS2 To express oneself MSYS2 The installation directory （ It's your own situation ）.

              step3、make

              step4、 make install

              After the compilation is successful, it will be in $MSYS2/usr/local/SDL2/  Corresponding library directory （ If it is not generated, you need to carefully check whether there are errors in the above three steps ）：

        4）、 Record the compilation process and report an error , stay SDL2-2.0.18 and SDL2-2.0.22 Versions have encountered .make Step compilation SDL_windows_gaming_input.c, The error information is as follows ：

        make: *** [makefile:730: build/sdl_windows_gaming_input.lo] error 1

        This is supposed to be windows Define the type and linux There are differences , It needs to be revised  SDL_windows_gaming_input.c（$MSYS2/home/source/SDL2-2.0.18/src/joystick/windows） file , Add new macro （ Here is the reference SDL issue solve , The path is pasted at the end ）. The modification is as follows ：

// Add macro 
#ifdef __MINGW32__
#define __FIReference_1_int __FIReference_1_INT32
#define __FIReference_1_int_get_Value __FIReference_1_INT32_get_Value
#define __FIReference_1_int_Release __FIReference_1_INT32_Release
#endif

// Source code 
struct joystick_hwdata
{
    __x_ABI_CWindows_CGaming_CInput_CIRawGameController *controller;
    __x_ABI_CWindows_CGaming_CInput_CIGameController *gamecontroller;
    __x_ABI_CWindows_CGaming_CInput_CIGameControllerBatteryInfo *battery;
    __x_ABI_CWindows_CGaming_CInput_CIGamepad *gamepad;
    __x_ABI_CWindows_CGaming_CInput_CGamepadVibration vibration;
    UINT64 timestamp;
};

3、 compile ffmpeg        

    1）、 The environment needs to be configured

        stay mingw64 Execute the command in the command window ：

1、Pacman -S nasm

2、Pacman -S yasm

3、Pacman -S make cmake

4、 Pacman -S diffutils

    2）、 Set up SDL2 The Library Directory of

        export PATH="/usr/local/SDL2/bin/:$PATH"     

   3）、ffmpeg Compile instructions

1、./configure --enable-shared --disable-static --enable-debug --enable-sdl2 --extra-cflags='-I/usr/local/SDL2/include/SDL2/' --extra-ldflags='-L/usr/local/SDL2/lib/' --prefix=/home/source/ffmpeg_build/

2、make

3、make install

The library file generated after successful compilation is in  /home/source/ffmpeg_build/  Under the table of contents .
