pHash-0.9.6 patched version

pHash-0.9.6 was released at 2013-04-23, but there are serveral problems for certain usage

Based on yftzeng's work for two patches:

  1. Compatible with new PHP version (Compile/Install passed).
  2. Change ph_dct_imagehash() function to return hash string for further operation.

And in addition, I added two patches for ffmpeg 2.3+ compatibility, which is also for the ruby binding compatibility

  1. Add init NULL value for pFormatCtx (Fixed Video hash)
  2. extern "C" for all functions in audiophash.h (Fixed Audio hash)

Installation

Ubuntu

1. pHash

$ sudo apt-get install libavformat-dev libmpg123-dev libsamplerate-dev libsndfile-dev
$ sudo apt-get install cimg-dev libavcodec-dev ffmpeg libswscale-dev

$ cd pHash-0.9.6
$ ./configure
$ make && sudo make install

2. Ruby binding

https://github.com/toy/pHash

gem install pHash

3. PHP binding

$ cd bindings/php
$ phpize
$ ./configure LIBS="-lpthread"
$ make && sudo make install

If you have PHP 5:

$ sudo vi /etc/php5/conf.d/pHash.so
extension=pHash.so

$ sudo php5enmod pHash
$ php -m
pHash

If you have PHP 7:

sudo echo "extension=pHash.so" | sudo tee /etc/php/7.0/mods-available/pHash.ini
sudo phpenmod pHash
php -m
# you should see pHash in the list
