ijkplayer 大佬提供一下集成x264编码以及aac的详细步骤

我按照https://www.jianshu.com/p/ce67fed1cf09这条简书上的步骤编译，出现错误
这是编译时报的错误
use_pkg_config libx264 x264 stdint.h x264.h x264_encoder_encode
check_pkg_config libx264 x264 stdint.h x264.h x264_encoder_encode
pkg-config --exists --print-errors x264
Package x264 was not found in the pkg-config search path.
Perhaps you should add the directory containing `x264.pc'
to the PKG_CONFIG_PATH environment variable
No package 'x264' found

Begin with the linked Jianshu build instructions and the reported FFmpeg configure output; trace how the iOS build discovers x264 through pkg-config and x264.h. Confirm the required x264 and AAC integration steps for ijkplayer, documenting reproducible commands and the expected successful checks.
