Macos OpenCV编译过程失败
因此，我将在下面介绍如何为Python3安装openCV。我在编译过程中遇到了一些问题。运行Macos OpenCV编译过程失败,macos,opencv,ffmpeg,Macos,Opencv,Ffmpeg,因此，我将在下面介绍如何为Python3安装openCV。我在编译过程中遇到了一些问题。运行make-j4命令会一直正常运行，直到我收到此错误消息时28%通过：错误：使用未声明的标识符“avcodec_free_frame”；你是说“avcodec\u get\u name”吗？ 我甚至不知道从哪里开始解决这个问题。我已经通过brew安装了ffmpeg 完整的命令列表： cd ~ git clone https://github.com/Itseez/opencv.git cd opencv g
