ffmpeg mingw32 ffplay编译， dm6446 ./configure参数 dm6446 tftp nfs启动参数

[stan8688]

build ffmpeg on windows

1.get ffmpeg source with svn
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

2.build mp3 support
cd lame-3.96.1
./configure --enable-shared --prefix=/local
这里推荐尽量装在/usr下，默认是装在/usr/local下。这样ffmpeg要指定/local编译都能顺利的找到库文件

3. build liba52 - a free ATSC A/52 stream decoder
download http://liba52.sourceforge.net/
# tar zxvf a52dec-0.7.4.tar.gz
# cd a52dec-0.7.4
# ./configure --enable-shared --prefix=/local
# make
# make install

//windows平台 mingw32下 ffplay 和库文件 could play ok
