FFMPEG 和 FFMPEG-PHP 的安装

 REQUIREMENTS
============

ffmpeg-0.4.9pre1 or higher built with the –enable-shared option (ffmpeg cvs recommended)
php-4.3.x or higher
gd-2.0.x or higher or the version of GD bundled with PHP

INSTALLATION INSTRUCTIONS
=========================

These instructions are for Linux since I don’t have windows. If you
successfully build on windows, let me know how you did it and I’ll update
the instructions.

BUILDING FFMPEG
—————

cd /path/to/ffmpeg
./configure –enable-shared –prefix=/usr/local
make clean && make
[become root]
make install

BUILDING FFMPEG-PHP AS A SHARED EXTENSION
—————————————–

1. Build php if not already built or installed by your distro (See the file INSTALL in your php source
directory)

2. Unpack the archive

tar -xjf ffmpeg-php.X.XX.tar.gz

3. cd into the ffmpeg extension directory

cd ffmpeg-php.X.XX/

4. Run phpize (included with your php install) to build configuration files

phpize

5. Configure and build

./configure
在这步将会出现Make sure you’ve built ffmpeg as shared libs using the –enable-shared option错误

Here is the solution:

Step1: cd /usr/local/include/ffmpeg

Check if you have the ffmpeg directory created under /usr/local/include.
I did not have if myself, so I had to create it.
If you do not have it either, then create it and go to step 2.

Step 2:
cp -p /usr/local/src/ffmpeg/libavformat/avio.h /usr/local/include/ffmpeg
cp -p /usr/local/src/ffmpeg/libavformat/avformat.h /usr/local/include/ffmpeg
cp -p /usr/local/src/ffmpeg/libavcodec/avcodec.h /usr/local/include/ffmpeg

Step 3: configure, make, and make install your ffmpeg package. Not
your ffmpeg-php package, that one you do after you do your ffmpeg.

6. Install the shared extension

make
make install (as root)

If everything went as planned, ffmpeg-php is now installed as a shared library.
You must explicitly load it in your scripts using dl(ffmpeg.so) or if you want
it available to all scripts by default add extension=ffmpeg.so to your php.ini
file which will tell php to load it when starting up.

BUILDING FFMPEG-PHP AS PART OF THE PHP BINARY
———————————————

1. Unpack the archive and copy the ffmpeg extension directory into your the php
sources extensions directory

tar -xjf ffmpeg-php.X.XX.tar.gz
cp ffmpeg /path/to/php_sources/ext

2. Run autoconf to rebuild the php configure script and add the –with-ffmpeg
option

cd /path/to/php_sources
autoconf

2. configure php using…

./configure –with-ffmpeg=yes

…and build and install php.

The ffmpeg-php methods should now be built directly into php and so no need to
explicitly load the extension at runtime.

TESTING THE INSTALLATION
————————

1. Put the directory test_media and test_ffmpeg.php script under your web root
somewhere (put both in the same directory).

2. Load test_ffmpeg.php into your browser.

RESULTS: You should get a listing of the methods provided by the ffmpeg-php
module as well as some test output from the methods.
