linux下静态编译ffmpeg及opencv的C++工程
由于工作需要，需要将之前在WINDOWS平台上开发的一个使用到opencv和ffmpeg sdk的工程移植到linux下，由于考虑部署方便，想使用静态编译的方式。为了搭建这个编译环境，可以说是费了九牛二虎之力，最终终于把所有的包收集齐，并且搭建好工程。
注意事项：
1、opencv默认是附带ffmpeg的，其编译安装时默认需要使用ffmpeg的库。
2、由于ffmpeg更新频繁且一些新版本未必稳定（或者老有修改接口的习惯），我们希望使用的ffmpeg sdk与opencv用到的ffmpeg完全无关
3、opencv默认带了一大堆功能，静态编译会使得文件比较庞大， 我们有必要对其进行一定量的瘦身。
我这里使用当前opencv最新版本2.4.3，具体的安装方法可以参考文章http://www.ozbotz.org/opencv-installation/
但是我们需要静态编译且瘦身的话，需要修改其CMakeList.txt文件，我的修改如下

编译安装后会在/usr/local/include和/usr/local/lib下生成相关的头文件和.a文件
FFMPEG静态编译后得到相关的.a文件。
然后我们搭建整个工程，需要解决一堆.a文件的依赖性，这里可以参考我的makefile中的库的依赖
LIBS=-Llib-linux/ffmpeg \
-lavdevice -lavfilter -lavcodec -lavformat -lavresample -lavutil -lpostproc -lswresample -lswscale \
-lxvidcore -lx264 -lvorbisenc -lvorbis -logg -lvo-amrwbenc -lvo-aacenc -ltheoraenc -ltheoradec \
-lspeex -lopenjpeg -lopencore-amrwb -lopencore-amrnb -lmp3lame -lcelt0 \

-lopencv_contrib -lopencv_stitching -lopencv_ts -lopencv_videostab -lopencv_gpu \
-lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_calib3d \
-lopencv_photo -lopencv_video -lopencv_features2d -lopencv_highgui -lopencv_flann \
-lopencv_imgproc -lopencv_core -lz -ljpeg -lpng值得一提的是：C++的编译选项中还需要增加一些静态相关的库
-lm -lrt -static-libgcc -static-libstdc++ -Llib-linux -lpthread -static -lc
搭建好后，可以编译
