php在线处理视频 (在线视频转码,取得视频信息)

 

1.创建文件夹

mkdir ~/ffmpeg
cd ~/ffmpeg

 

2.取得基本要求的源文件

wget http://www.mplayerhq.hu/MPlayer/releases/codecs/all-20100303.tar.bz2

or

wget http://www.mplayerhq.hu/MPlayer/releases/codecs/essential-20071007.tar.bz2

wget http://rubyforge.org/frs/download.php/17497/flvtool2-1.0.6.tgz

or

wget http://ftp.de.debian.org/debian/pool/main/f/flvtool2/flvtool2_1.0.6-4.tar.gz

wget http://downloads.sourceforge.net/project/lame/lame/3.98.4/lame-3.98.4.tar.gz
wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2
wget http://downloads.xiph.org/releases/ogg/libogg-1.2.0.tar.gz
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.1.tar.gz

wget http://www.tortall.net/projects/yasm/releases/yasm-1.1.0.tar.gz

 

3.解压源文件

bunzip2 all-20100303.tar.bz2; tar xvf all-20100303.tar

or

bunzip2 essential-20071007.tar.bz2; tar xvf essential-20071007.tar.bz2

tar zfvx flvtool2_1.0.6-4.tar.gz
tar zxvf lame-3.98.4.tar.gz
bunzip2 ffmpeg-php-0.6.0.tbz2 ;tar vxf ffmpeg-php-0.6.0.tar
tar zvxf libogg-1.2.0.tar.gz
tar zxvf libvorbis-1.3.1.tar.gz

bunzip2 rpl-4.0.19.tar.bz2; tar vfx rpl-4.0.19.tar

 

4.创建codecs文件夹并导入

mkdir /usr/local/lib/codecs/
mv all-20100303/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

 

5.取得FFMPEG和Mplayer

svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

 

6.编译lame

cd lame-3.98.4

./configure
make
make install

cd ..

 

7编译libOGG
cd cd libogg-1.2.0
./configure
make
make install

Cd ..

 

8. 编译libVorbis
cd libvorbis-1.3.1
./configure
make
make install

cd ..

 

9 编译 flvtool2

cd flvtool2/
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

cd ..

 

10.编译yasm(安装mplayer必须)

tar zfvx yasm-1.1.0.tar.gz

cd yasm-1.1.0

./configure

make

make install

 

11. 编译mplayer

MPlayer
cd mplayer
./configure
make
make install

cd ..

 

12. 编译ffmpeg

cd ffmpeg

./configure --enable-libmp3lame --enable-libvorbis --disable-mmx --enable-shared --enable-yasm
echo '#define HAVE_LRINTF 1' >> config.h

make
make install

cd ..

 

13.建立链接

ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51

 

15.编译PHP的FFmpeg扩展

cd ffmpeg-php-0.6.0

/usr/local/php/bin/phpize  #我的PHPIZE在这里

./configure --with-php-config=/usr/local/php/bin/php-config #我的php-config在这里
make

#可能出现错误:error: ‘PIX_FMT_RGBA32′ undeclared (first use in this function)
#make: *** [ffmpeg_frame.lo] Error 1

#打开文件 “/ffmpeg-php-0.5.0/ffmpeg_frame.c”

# 替换所欲的 PIX_FMT_RGBA32 为 PIX_FMT_RGB32 #vi 命令 :%s/PIX_FMT_RGBA32/PIX_FMT_RGB32/
make install

cd ..

vi /usr/local/php/etc/php.ini

往结尾添加

extension=/usr/local/lib/php/extensions/ no-debug-non-zts-20020429/ffmpeg.so #这个SO的地址根据你的实际的写

#注:根据PHP的配置不同.部分可能直接会自动添加而无需手动

 

16 重启web 服务,检查是否有ffmpeg 扩展出现

明天把PHP端如何处理补上.
