Question

试图编译x265以与arm64-v8a一起使用。成功构建x265本身后，ffmpeg即将编译时，我收到以下错误：

我使用ffmpeg 4.1.3和x265源的最新版本。我使用this项目进行编译，并且在没有x265的情况下构建成功。我在Debian Buster x64上编译。

Answer 1

我最终使用了this项目中的脚本，该脚本使用所有最新的NDK和ffmpeg以及每个最新的库，以创建ffmpeg二进制文件。它在我的设备上工作得很好，并且通过修改一点，我也得到了一个静态的ffmpeg。我只需要在我的应用程序中添加2个额外的本机库即可运行。它甚至使用了所有CPU功能，因此是移动设备最快的解决方案。

使用ffmpeg为Android编译x265并收到错误
