参考：http://www.ffmpeg.com.cn的 Ffmpeg快速安装教程


根据上述的教程，在安装过程中，碰到的问题。黑色字为教程中的内容，红色字为本人进行注释。


安装 

##### lame #####

lame-CVS20050706-i686-1jto.tgz解压后

复制lame中./usr/include ./usr/bin ./usr/lib 三个文件夹到服务器对应地方




##### ffmpeg #####

cd ffmpeg

./configure –prefix=/usr/local –enable-memalign-hack –enable-mp3lame –enable-shared

make

make install

cd..

cp -r /usr/local/lib/libav*.so /usr/lib

注：–prefix=/usr/local不得修改，否则ffmpeg-php安装不上

    运行/usr/local/bin/ffmpeg –v测试是否安装成功
注：由于新版的编译参数有所改变其中–enable-mp3lame 应改为–enable-libmp3lame 测试是否安装成功，提示ffmpeg: error while loading shared libraries: libavformat.so.51: cannot open shared object file: No such file or directory处理方法，vi /etc/ld.so.conf 在里面添加/usr/local/lib 然后运行/sbin/ldconfig 即可




##### Apache2 #####

cd httpd-2.0.54

./configure –enable-so –prefix=/server/httpd –with-config-file-path=/server/httpd/conf

make

make install

cd ..

注：

运行/server/httpd/bin/httpd –k start http://192.168.1.xxx测试是否安装成功

测试完后要关闭/server/httpd/bin/httpd –k stop




##### FreeType #####

cd freetype-2.1.10

./configure –prefix=/usr/local/freetype

make

make install

cd ..




##### LibPNG #####

cd libpng-1.2.8

./configure –prefix=/usr/local/libpng –enable-shared –enable-static

make test

make install

cd ..




##### Jpeg #####

cd jpeg-6b

mkdir /usr/local/jpeg

mkdir /usr/local/jpeg/bin

mkdir /usr/local/jpeg/lib

mkdir /usr/local/jpeg/include

mkdir /usr/local/jpeg/man

mkdir /usr/local/jpeg/man/man1

./configure –prefix=/usr/local/jpeg –enable-shared –enable-static

make

make install

cd ..




##### zlib #####

cd zlib-1.2.2

./configure

make

make install

cd ..




##### GD Library #####

cd gd-2.0.33

./configure –prefix=/usr/local/gd –with-jpeg=/usr/local/jpeg –with-freetype=/usr/local/freetype –with-png –with-zlib

make

make install

cd ..




##### ffmpeg-php #####

按照官方的说法，可以在装php前安装ffmpeg-php

但是我没成功

运行不了phpize

因此此步在装了php后再进行

有点傻




##### PHP #####

cd php-4.3.11

./configure –prefix=/server/php –with-apxs2=/server/httpd/bin/apxs –with-gd=/usr/local/gd –enable-gd –enable-gd-native-

ttf –with-jpeg-dir=/usr/local/jpeg –with-png –with-ttf –with-zlib –with-freetype-dir=/usr/local/freetype –with-config-

file-path=/server/httpd/conf

make

make install

cp php.ini-dist /server/httpd/conf/php.ini

cd ..




##### ffmpeg-php #####

mv ffmpeg-php /path/to/php_sources/ext/ffmpeg

cd /path/to/php_sources

autoconf

./configure –prefix=/server/php –with-apxs2=/server/httpd/bin/apxs –with-gd=/usr/local/gd –enable-gd –enable-gd-native-

ttf –with-jpeg-dir=/usr/local/jpeg –with-png –with-ttf –with-zlib –with-freetype-dir=/usr/local/freetype –with-config-

file-path=/server/httpd/conf –with-ffmpeg=/user/local/include

make

make install




  • 安装完毕 
运行 /server/httpd/bin/httpd –k start

测试

<?

phpinfo();

?>

[编辑] 如何使PHP支持ffmpeg（ffmpeg-php模块的安装）

下载ffmpeg安装包地址: http://ffmpeg.mplayerhq.hu/download.html

使用该命令下载ffmpeg: svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

./configure –enable-share –prefix=/usr

make clean && make && make install


下载ffmpeg-php安装包地址: http://ffmpeg-php.sourceforge.net/

tar -xvf ffmpeg-php-0.4.9.tar

mv ffmpeg-php-0.4.9 php-4.3.6/ext/ffmpeg

cd php-4.3.6/ext/ffmpeg

phpize

cd /opt/software/php-4.3.6

rm configure

./buildconf –force

第二次编译php，让它支持ffmpeg-php 

./configure –with-png-dir=/usr –with-gd –enable-gd-native-ttf –with-ttf –with-freetype –without-gdbm –with-gettext —

with-ncurses –with-gmp –with-iconv –with-jpeg-dir=/usr –with-png –enable-ftp –enable-sockets -with-xml –with-dom —

with-zlib –enable-track-vars –with-mysql –with-apxs2=/usr/local/apache2/bin/apxs –with-ffmpeg=/user/local/include

make && make install


加粗为需要注意的地方,路径或参数不同会造成无法加载ffmpeg.so的错误.

错误提示如:

Warning: dl(): Not supported in multithreaded Web servers – use extension statements in your php.ini

FFMPEG 和 FFMPEG-PHP 的安装

[编辑] 获取ffmpeg源代码


This tutorial is about transcoding video fom one codec into another using FFMPEG. I got deeper into FFMPEG when I wanted to transcode into FLV (Flash Video) and it works very well. I developed the Riva FLV Encoder, a GUI for FFMPEG.


Update 26.10.2006: This tutorial is a little outdated as there were many changes in FFMPEG like the switch from CVS to Subversion and the workflow to compile FFMPEG under Windows has become more difficult. For the new tweaks check this tutorial.



  • Download MinGW ” MSYS current releases (Window Exe Binaries MSYS-1.0.10.exe & MinGW-3.1.0-1.exe)


Install MinGW
Install MSYS
HINT: During the Postinstall be sure to set the right path to MinGW with a “/” instead of a Windows-“”. If you did it wrong anyway re-install MSYS to the same directory and do the postinstall right (I missed it a few times)


  • Download and compile Lame


Extract Lame to your MSYS home-directory
Open MSYS and change to your lame-directory (cd ../lame-XXX)
Enter the following commands: 
./configure //(takes a few minutes)

make //(lame is being comiled; takes a few minutes, too)

make install


After installing you will recognize that there are new directories and files in MSYS/local which we will use while compiling ffmpeg with mp3-support



Check out the sourcecode from svn://svn.mplayerhq.hu/ffmpeg


  • Compile FFMPEG


Change the directory in MSYS to your ffmpeg-directory (cd ../ffmpeg)
Enter the command: 
./configure –enable-memalign-hack –enable-mingw32 –enable-mp3lame –extra-cflags=-I/local/include –extra-ldflags=-L/local/lib


HINT: you can paste into MSYS by pressing your center mouse-button
1. “–enabled-memalign-hack” is a Windows hack. Without this option ffmpeg always crashs with the message “removing common factors from framerate” when encoding AVIs.
2. “–enable-mingw32”. I see no difference without it but we compile with MinGW and it would not do a harm when ffmpeg knows this
3. “–enable-mp3lame”: Enable transcoding audio with the open-source mp3-lame-codec
4. “–extra-cflags=-I/local/include –extra-ldflags=-L/local/lib”: The cflags- and ldflags-parameter sets the right path to your lame-installation which you did in step 3.d.


Enter command: make (ffmpeg is being compiled; takes a few minutes) With “make install” you could now copy the ffmpeg.exe to c:Program Filesffmpeg. But there is no need to.


MSYS是什么,他与CYGWIN有什么区别?


[编辑] Use FFMPEG



Copy your compiled ffmpeg.exe from your MSYS directory to the directory where you like to transcode with ffmpeg
Open the Dos-Shell and change to the directory where you copied the ffmpeg.exe
Copy a test.mpg into your directory and enter the following command: 
ffmpeg -i test.mpg -ab 56 -ar 22050 -b 500 -r 15 -s 320×240 test.flv




Your first FLV should be encoded now



[编辑] Render Images from a Video


Enter command: 

ffmpeg -an -y -t 0:0:0.001 -i test.flv -f image2 test%d.jpg


HINT: With -t you set the length of images to be extracted. Above we entered 1 millisecond the extract one image. If you miss this parameter all images of the video will be extracted



[编辑] ZLib Support


(e.g. for TSCC and Quicktime codecs). This should be compiled into FFMPEG. It is not an explicit compile in the configure statement. Do the following steps and after configure you should see that zlib is “on”.



Download and compile ZLib
Extract the files to your mysys directory
Change the directory in MSYS to that directory
Enter command 
./confugure

make

make install.

[编辑] AC3 Support


Add “–enable-a52 –enable-gpl” to your configure command




[编辑] 3GP Support


If you want to enable 3GP support you have to add the AMR audio codec. Download the TS26.104 REL-5 V5.1.0 26104-5??.zip here. Extract the codec into libavcodec/amr_float and add “–enable-amr_nb” to your configure command




[编辑] XVID Support


(thanks to garvin.thornten at datel.co.uk) Download and install the codec from www.xlib.org (see xvidcore-xxxx/doc/install). Add “–enable-xvid –enable-gpl” to your configure command. When compiling with xvid codec in MinGW or cygwin you will get a “mkstemp” error when compiling “xvidff.c”. To fix this edit “libavcodec/xvidff.c” and add the following after the #includes. This will probably be fixed in a future ffmpeg release: ´ 



/* Added for windows compile —————– */

#include


int xvid_ff_2pass(void *ref, int opt, void *p1, void *p2); void xvid_correct_framerate(AVCodecContext *avctx);


int mkstemp(char* template)


char temppath[512];

if(GetTempPath(512,temppath)!=0)

{

 if(GetTempFileName(temppath,”fil”,0,template)!=0)

 {

  FILE *pFile;

  pFile=fopen(template,”w+”);

  if(pFile!=NULL)

  return (int)pFile;

 }

}

 return -1;

}
