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
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 && make

6. Install the shared extension 

        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.

TROUBLESHOOTING
---------------

Q: I get '`gdImage' undeclared or `gdImagePtr''undeclared when I try to 
   'make' ffmpeg-php

A: Your version of php is compiled without gd support. Make sure to use the 
   '--with-gd' flag when configuring php. If you're sure you have gd but 
   it is not being detected you can change the line...

   //#define HAVE_LIBGD20

   ...to...

   #define HAVE_LIBGD20

   ...in ffmpeg_frame.h and run...
   
   make clean && make 
   
   ...to force ffmpeg to recompile with gd support.

Q: I get 'avcodec.h: No such file or directory' when I try to 'make' ffmpeg-php 

A: ffmpeg-php can't find ffmpeg header files. Make sure when you configure 
   ffmpeg you use the '--enable-shared' option and make sure it installs 
   somewhere where other programs can find the libs/headers. See 
   'BUILDING FFMPEG' above for an example.
 
HELP
----

This INSTALL doc is not very comprehensive. If you get stuck, post a message 
to the ffmpeg-php google group (http://groups-beta.google.com/group/ffmpeg-php)
and I'll try to help.
