tiny4412 移植ffmpeg 不适用命令行,使用C代码方式压缩视频

1.ubuntu 16.04 编译x264

./configure --host=arm-linux --prefix=/x264-asm --enable-shared --disable-asm 

编辑config.mak

3.测试ffmpeg

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

4.移植文件到目标板

全部拷贝下

ffmpeg-4412/bin/*

ffmpeg-4412/lib/* 

ffmpeg-4412/include/*

x264-4412/lib/* 

x264-4412/include/*

到4412开发板根目录下的lib  include

5.移植文件到交叉工具链里

全部拷贝下

ffmpeg-4412/lib/* 

ffmpeg-4412/include/*

x264-4412/lib/* 

x264-4412/include/*

到 ubuntu    /opt/FriendlyARM/toolschain/4.5.1/arm-none-linux-gnueabi目录下的lib  include
