  • ffmpeg not using all cores

    4 novembre 2013, par kkgzjjmj

    I just got my new server with two intel e5-2695 but I was shocked to see that ffmpeg or ubuntu doesn't utilize all cores.

  • Unable to link with libx264.lib static library

    3 novembre 2013, par dtumaykin

    I’m building custom video encoder using x264 as a static library. I’ve followed this guide in order to build static library. Trying to compile this :

    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);
    }

    Results in :

    main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_default_preset(struct x264_param_t *,char const *,char const *)"

    main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_apply_profile(struct x264_param_t *,char const *)"

    main.obj : error LNK2019 : unresolved external symbol "struct x264_t * __cdecl x264_encoder_open_136(struct x264_param_t *)"

    %PROJECT_DIR% : fatal error LNK1120 : 3 unresolved externals

    Linker scans libx264.lib, but can’t find anything inside.

    Searching .\lib\libx264.lib:

    With dumpbin /HEADERS I can actually find the declaration I need, but linker is unable to do it.
