配置ffmpeg的configure时，找不到x265的错误
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg
#输出还是会报错
ERROR: x265 not found using pkg-config
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
首先pkg-config --list-all | grep x265看看pkg-config有没有找到x265.pc
没找到则需要配置下
pkg-config --list-all | grep x265 #看看有没有输出x265相关信息
echo $PKG_PKG_CONFIG_PATH #看看有没有找到x265.pc
export PKG_PKG_CONFIG_PATH=$PKG_PKG_CONFIG_PATH:/path/x264/lib/pkgconfig:/path/x265/lib/pkgconfig #替换成你的路径
pkg-config --list-all | grep x265 #可以找到x265路径了
以上步骤都是必须确认的 再次执行
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg
#输出还是会报错

经过查资料得知
configure还需要加上
--extra-libs="-lpthread" --pkg-config-flags="--static"
于是
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg --extra-libs="-lpthread" --pkg-config-flags="--static"
#终于成功了
install prefix ../ffmpeg
