在ffmpeg的Android组建libx264 EN codeR错误 [英] libx264 encoder error in ffmpeg android build
问题描述
现在，我不得不承认libx264并成功地编译一个ffmeg构建脚本。我也编X264和libx264.a文库获得。双方的ffmpeg和libx264从源代码构建。我可以建立的ffmpeg没有libx264成功地为好。下面你会发现我的脚本尝试构建与ffmpeg的libx264。

是
以上脚本不给我libx264.a在ffmpeg的输出builds.Several其他情况如下。
如果我能带X264 codeR，我得到了一个未定义引用错误在x264.c一些变量（在libav codeC）。
如果我的ffmpeg配置启用共享，我得到它说的错误它不能cd到我的preFIX目录（顺便说一句无权限问题）。
我使用的ffmpeg和X264的最新版本（克隆了git的今天）和NDK 7的Ubuntu上运行虚拟机，安装在Windows 7上关于我的ffmpeg / X264移植到Android的冒险有关详细信息，您可以参阅< A HREF =http://stackoverflow.com/questions/12200172/yet-another-ffmpeg-libx264-issue>这里。
我应该怎么做与ffmpeg的使用libx264？我一直在试图用不同的配置这个脚本，删除了所有的ffmpeg x264的文件夹，并重新安装它们，但无济于事。
感谢很多提前。

Right now, I have a ffmeg build script which recognizes libx264 and compiles succesfully. I have also compiled x264 and obtained libx264.a library. Both ffmpeg and libx264 are built from source. I can build ffmpeg without libx264 succesfully as well. Below you may find my script which tries to build ffmpeg with libx264.

Above script doesn't give me libx264.a in ffmpeg output builds.Several other scenarios are as follows. If I enable x264 encoder, I get undefined reference errors to some variables in x264.c (in libavcodec). If I enable shared in ffmpeg configure, I get an error which says it can't cd to my prefix directory (no permission issues by the way).
I am using latest releases of ffmpeg and x264 (cloned the git today) and ndk 7. Ubuntu runs on VM, installed on Windows 7. For further details about my adventure of ffmpeg/x264 porting to Android, you may refer here.
What should I do to use libx264 with ffmpeg? I kept on trying this script with different configurations, removed all ffmpeg x264 folders and reinstalled them, but to no avail.
Thanks a lot in advance.
EDIT Below is my x264 build script. It builds fine, gives me the static library and the headers.

This is what happens on terminal when i enable libx264 encoder.

look at above link and how eighthave includes L..X264 in his ./ffmpeg/configure...
if u get the correct libs into the search chain for the config step on ffmpeg , then all those undefined refs go away...
