windows - libx264 没有找到 FFmpeg？

问题描述

我正在尝试构建启用了 libx264 的 ffmpeg。但是，当我在 MSYS 中运行以下命令时

./configure --prefix=ffmpeg/ --enable-gpl --enable-libx264

我收到一条错误消息

ERROR: libx264 not found

我在 Windows 10 上使用 MSYS。我还安装了 NASM。这是 config.log 文件

    4   long check_x264_encoder_encode(void) { return (long) x264_encoder_encode; }
    5   int main(void) { int ret = 0;
    6    ret |= ((intptr_t)check_x264_encoder_encode) & 0xFFFF;
    7   return ret; }

你能告诉我如何解决这个错误，还是里面已经有一个带有 libx264 的预构建包？
