如何解决在为android构建启用ffmpeg-with-libx264时未找到libx264？

Question

我想构建从git下载的android-ffmpeg-x264。链接https://github.com/halfninja/android-ffmpeg-x264

运行./config_make_everything.sh后我收到以下错误

ERROR：libx264没有找到

如果你想配置犯了一个错误，请确保您使用的是最新版本的 从混帐。如果最新版本失败，请将问题报告给irc.freenode.net上的 ffmpeg-user@ffmpeg.org邮件列表或IRC#ffmpeg。 包含由configure生成的日志文件“config.log”，因为这将有助于 解决问题。

1.I我使用的Fedora构建既FFMPEG和X264 2.NDK R7

任何解决方案才能成功构建的代码？

Answer 1

我还没有亲自证实过这一点，但我相信如果您将NDK降级为r5c，则可以解决此问题。请记住重新创建工具链。
