Android编译ffmpeg常见错误

作者: JXiaoNiu | 来源:发表于2019-01-31 16:52 被阅读0次

    1.编译环境
    FFmpeg 4.1
    NDK android-ndk-r15c

    2、错误1少文件

    makefile:2: ffbuild/config.mak: no such file or directory
    

    解决方法:
    先不要执行make和make install,第一步先在ffmpeg-4.1下执行./configure,该命令会自动生成缺少的文件

    3.错误2

    ../libavutil/libm.h:62: error: static declaration of 'lrint' follows non-static declaration
    ../libavutil/libm.h:69: error: static declaration of 'lrintf' follows non-static declaration
    ../libavutil/libm.h:76: error: static declaration of 'round' follows non-static declaration
    ../libavutil/libm.h:83: error: static declaration of 'roundf' follows non-static declaration
    ./libavutil/libm.h:90: error: static declaration of 'truncf' follows non-static declaration
    

    解决方法:
    config.h搜索lrint、lrintf、round、roundf等对应的字符

    #define HAVE_LLRINT 1
    #define HAVE_LLRINTF 1
    #define HAVE_LRINT 1
    #define HAVE_LRINTF 1
    #define HAVE_ROUND 1
    #define HAVE_ROUNDF 1
    

    将对应的值改为1即可

    3.错误3

    ffmpeg yasm not found, use --disable-yasm
    

    解决方法:
    下载yasm ,重命名为yasm.exe ,放到MinGW\bin 目录下

    4.错误4

    libavformat/os_support.c: In function 'ff_gai_strerror':
    libavformat/os_support.c:194:10: error: 'ERROR_NOT_ENOUGH_MEMORY' undeclared (first use in this function)
    

    解决方法:

    打开libavformat/os_support.h 文件,在其中增加 #include <winerror.h>

    5.错误5

     [install-libavdevice-static] Error 127
