我正在使用 x264 作为静态库构建自定义视频编码器。我已按照指南构建静态库。试图编译这个:

x264_t * setup_encoder(int width, int height){
    x264_param_t param;
    x264_param_default_preset(&param, "veryfast", "zerolatency");
    param.i_threads = 1;
    param.i_width = width;
    param.i_height = height;
    param.i_fps_num = 26;
    param.i_fps_den = 1;
    // Intra refres:
    param.i_keyint_max = 26;
    param.b_intra_refresh = 1;
    //Rate control:
    param.rc.i_rc_method = X264_RC_CRF;
    param.rc.f_rf_constant = 25;
    param.rc.f_rf_constant = 25;
    param.rc.f_rf_constant_max = 35;
    //For streaming:
    param.b_repeat_headers = 1;
    param.b_annexb = 1;
    x264_param_apply_profile(&param, "baseline");

    return x264_encoder_open(&param);
}

结果是:

main.obj:错误 LNK2019:无法解析的外部符号“int __cdecl x264_param_default_preset(struct x264_param_t *,char const *,char const *)”

main.obj:错误 LNK2019:未解析的外部符号“int __cdecl x264_param_apply_profile(struct x264_param_t *,char const *)”

main.obj:错误 LNK2019:未解析的外部符号“struct x264_t * __cdecl x264_encoder_open_136(struct x264_param_t *)”

%PROJECT_DIR%:致命错误 LNK1120:3 个未解决的外部

链接器扫描 libx264.lib,但在里面找不到任何东西。

Searching .\lib\libx264.lib:

使用 dumpbin /HEADERS 我实际上可以找到我需要的声明,但链接器无法做到这一点。

SECTION HEADER #38
   .text name
       0 physical address
       0 virtual address
     E60 size of raw data

环境是在 Windows 8 64 位上使用 Intel Compiler 14 的 Visual Studio 2012。

尝试包括使用 C 样式绑定。

extern "C" {
#include <x264.h>
}
