配置ffmpeg的configure時，找不到x265的錯誤
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg
#輸出還是會報錯
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有沒有找到x265.pc
沒找到則需要配置下
pkg-config --list-all | grep x265 #看看有沒有輸出x265相關資訊
echo $PKG_PKG_CONFIG_PATH #看看有沒有找到x265.pc
export PKG_PKG_CONFIG_PATH=$PKG_PKG_CONFIG_PATH:/path/x264/lib/pkgconfig:/path/x265/lib/pkgconfig #替換成你的路徑
pkg-config --list-all | grep x265 #可以找到x265路徑了
以上步驟都是必須確認的 再次執行
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg
#輸出還是會報錯

經過查資料得知
configure還需要加上
--extra-libs="-lpthread" --pkg-config-flags="--static"
於是
./configure --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --enable-libx264 --enable-libx265 --prefix=../ffmpeg --extra-libs="-lpthread" --pkg-config-flags="--static"
#終於成功了
install prefix ../ffmpeg
