1.進入到ffmpeg目錄中用以下方式配置：
$ ./configure --arch=arm --target-os=linux --cc=arm-linux-gcc --enable-cross-compile --enable-shared --disable-network --disable-armv6 --disable-armv6t2 --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-avfilter --enable-gpl --enable-swscale
--enable-postproc --enable-gpl --enable-pthreads
出現如下問題：
Must specify target arch and OS when cross-compiling
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.
通過./configure –help找到相關配置選項，傳遞linux給此選項，配置通過
2.拷貝目標文件：
拷貝如下頭文件到/home/liwei/ffmpeg_install/include(實際爲安裝解碼庫時安裝到系統目錄下的頭文件)
/usr/local/include/*
拷貝如下動態庫文件到/home/liwei/ffmpeg_install/lib：
ffmpeg/libavcodec/libavcodec.so.53
ffmpeg/libavfilter/libavfilter.so.2
ffmpeg/libpostproc/libpostproc.so.52
ffmpeg/libavformat/libavformat.so.53
ffmpeg/libswresample/libswresample.so.0
ffmpeg/libavdevice/libavdevice.so.53
ffmpeg/libavutil/libavutil.so.51
ffmpeg/libswscale/libswscale.so.2
拷貝如下靜態庫文件到/home/liwei/ffmpeg_install/lib：
ffmpeg/libavcodec/libavcodec.a
ffmpeg/libavfilter/libavfilter.a
ffmpeg/libpostproc/libpostproc.a
ffmpeg/libavformat/libavformat.a
ffmpeg/libswresample/libswresample.a
ffmpeg/libavdevice/libavdevice.a
ffmpeg/libavutil/libavutil.a
ffmpeg/libswscale/libswscale.a
用arm-linux-strip工具去除動態庫中的調試信息：
$cd /home/liwei/ffmpeg_install/lib/
$ arm-linux-strip *.so
