3.測試ffmpeg

ffmpeg -s 1280*720 -pix_fmt yuv422 -i cam.yuv -vcodec mpeg4 output.avi

4.移植檔案到目標板

全部拷貝下

ffmpeg-4412/bin/*

ffmpeg-4412/lib/* 

ffmpeg-4412/include/*

x264-4412/lib/* 

x264-4412/include/*

到4412開發板根目錄下的lib  include

5.移植檔案到交叉工具鏈裡

全部拷貝下

ffmpeg-4412/lib/* 

ffmpeg-4412/include/*

x264-4412/lib/* 

x264-4412/include/*

到 ubuntu    /opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi目錄下的lib  include
