编译ffmpeg

1.下载ffmpeg-0.9.2.tar.gz  http://ffmpeg.org/releases/ 下载需要的版本

2.编译linux (centos5.5) 64位版本

./configure --prefix=/home/chulk/ffmpeg-x64 --arch=x86_64 --host-os=linux  --enable-shared --disable-w32threads --disable-bzlib --disable-zlib --disable-os2threads --disable-doc  --disable-ffprobe --disable-swresample --disable-debug --disable-ffmpeg --disable-ffserver --disable-ffplay --disable-avdevice --disable-avfilter --disable-network --disable-muxers --disable-filters --enable-demuxers --disable-devices --disable-protocols --disable-bsfs --disable-parsers --disable-encoders --disable-hwaccels --disable-yasm --enable-pthreads --enable-static --enable-memalign-hack --enable-small --disable-decoders --enable-decoder=h264 --enable-decoder=h263 --enable-decoder=mpeg4 --enable-decoder=mp3 --enable-decoder=mp2 --enable-decoder=aac
