Linux下MIPS平台交叉编译FFmpeg库

1.下载ffmpeg库的源代码

 (
http://sourceforge.net/project/showfiles.php?group_id=205275&package_id=248632):

 [root@localhost ffmpeg]# ls

 ffmpeg-laster.tar.gz

 2.解压:

 [root@localhost ffmpeg]# tar zxvf ffmpeg-laster.tar.gz 

 3.开始配置，并编译:

 [root@localhost ffmpeg]# mkdir /opt/ffmpeg

 [root@localhost ffmpeg]# cd ffmpeg

 [root@localhost ffmpeg]# ./configure --enable-cross-compile --target-os=linux --cross-prefix=mips-linux-gnu- --cc=mips-linux-gnu-gcc --enable-shared --arch=mips --prefix=/opt/ffmpeg

 [root@localhost ffmpeg]# make

 [root@localhost ffmpeg]# make install

 [root@localhost ffmpeg]# cd ../ffmpeg-release

 [root@localhost ffmpeg-release]# tar -zcvf ffjpeg_lib.tar.gz ./lib

板子上运行:
# cp ffjpeg_lib.tar.gz /usr/local/lib/
# cd /usr/local/lib/
# tar -zxvf ffjpeg_lib.tar.gz -C ../
# rm ffjpeg_lib.tar.gz

# cp ffmpeg-release/bin/* /bin/
# ffmpeg
