ERROR: libx264 version must be >= 0.115.

下载新的ffmpeg 0.85后，用以下方式configure，发现总是会有version的问题。

但是x264已经装好最新版。原因出自哪里？

./configure --prefix=/usr --enable-gpl --disable-shared --enable-libfaac --enable-libx264 --enable-nonfree --enable-memalign-hack --enable-debug --disable-ffplay --disable-ffprobe --disable-ffserver
ERROR: libx264 version must be >= 0.115.

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
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

 

我们看config.log.  搜索libx264。在文件的最后几行，发现如下问题。

4786 check_cpp_condition x264.h X264_BUILD >= 115
4787 check_cpp

原来，它检查的是usr/local/include下的x264.h文件。

而我的x264.h是安装在usr/include目录下了。 于是复制一份过来，问题解决了。

 

ffmpeg 0.80以后的版本好像需要0.116版本的x264
