我的目标是构建ffmpeg static libraries以便我可以将它们与jni一起使用并直接调用ffmpeg中定义的函数将一系列图像编码为h264视频流，并使用android 2.3.6中的GLSurfaceVIew在屏幕上呈现它
使用https://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html我知道通过拥有所需的.so文件和标题，我可以做到这一点。
我跟随Android NDK & FFMPEG build和其他许多人。无处不在我发现了roman10的构建脚本。
我使用Ubunthu 12.0.4 LTS与android-ndk-r9和ffmpeg-0.10源代码！
以下是我使用的构建脚本！

我怎样才能让它发挥作用，或者我是以错误的方式尝试？任何帮助都是适当的!!
如果有人指出我出错的原因。我不知道为什么nm显示错误，虽然它存在于指定的路径上！ 谢谢
