How to generate php documentation?

Hello!
How to generate php documentation from directory: https://github.com/sdepold/pHash/tree/master/bindings/php/manual?

load image from buffer

I wasn't able to find a way to load an image from a buffer (where the file was previously loaded) instead of directly from the file, is there anything somewhere or is it a limitation of the library (or of a dependency) ?

pHash won't build on recent Amazon Linux

Amazon Linux recently required gcc72 as a dependency of the kernel-devel package as of kernel-devel 4.14. This broke pHash builds on x64 Amazon Linux:

checking for uint64_t... no
configure: error:

*** Required type uint64_t not found.
pHash requires 64-bit integers for video and image hashes.

As a workaround, remove gcc72, libgcc72, and kernel-devel to get pHash to build.

False 1.0 similarity for PNG on Mac OS El Captain

I was using pHash via Ruby gem phash on a bit outdated Mac OS. After installing El Captain on new HDD (and so reinstalling pHash) it started to give false positive (1.0) similarity when at least one image is PNG. For example:

Values for JPEG didn't start to be wrong so when I convert the above images to JPEG, it says 0.46875
I forced an old version of gem ffi, but it had no effect -- probably smth changed in these binaries:

==> Caveats
The native FFmpeg AAC encoder has been stable since FFmpeg 3.0. If you
were using libvo-aacenc or libaacplus, both of which have been dropped in
FFmpeg 3.0, please consider switching to the native encoder (-c:a aac),
fdk-aac (-c:a libfdk_aac, ffmpeg needs to be installed with the
--with-fdk-aac option), or faac (-c:a libfaac, ffmpeg needs to be
installed with the --with-faac option).

See the announcement
https://ffmpeg.org/index.html#removing_external_aac_encoders for details,
and https://trac.ffmpeg.org/wiki/Encode/AAC on best practices of encoding
AAC with FFmpeg.

[Java Bindings] .so not being built on Ubuntu 16.04

Steps to reproduce:

sudo ./configure --enable-shared --enable-java --disable-audio-hash --disable-video-hash --disable-pthread
sudo make
cd bindings/java
javac org/pHash/*.java
sudo make install

Result:
java -Djava.library.path=/usr/local/lib org.pHash.pHash -mh img1.jpg img2.jpg

Exception in thread "main" java.lang.UnsatisfiedLinkError: no pHash-jni in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1867)
	at java.lang.Runtime.loadLibrary0(Runtime.java:870)
	at java.lang.System.loadLibrary(System.java:1122)
	at org.pHash.pHash.<clinit>(pHash.java:22)

Since there is no libpHash-jni.so nor libpHash.so at /usr/local/lib

Current code?

Is there where the active development is done?
I.e is this project abandoned?

Project Ownership

Hi,
I'd like to take ownership of this project.
I use pHash in one of my projects and have found that, because of it's inactivity Debian has dropped it from the repositories. I'm starting the process of getting it accepted again, but will need a git-repo to work from. For that I may was well use the closest thing to a canonical repo - which is this.
Any concerns/questions, do let me know.
Cheers.

[Crash] Query failed

Trying to query the mvptree on a large database.
In the function _ph_query_mvptree:

DP *sv1 = ph_read_datapoint(m);
DP *sv2 = ph_read_datapoint(m);

sv1 can be NULL.

So the following line will crash:
float d1 = hashdist(query,sv1);

pHash under package org.phash

After I move the classes under a package the following error occurs.

Exception in thread "main" java.lang.UnsatisfiedLinkError: org.phash.pHash.pHashInit()V
	at org.phash.pHash.pHashInit(Native Method)
	at org.phash.pHash.<clinit>(pHash.java:13)

Line 13
pHashInit();

Any ideas?
Thank you.
