If your blog get agged probably it get slow . To clean up old SQL entrys there are several plugins but some time like in my case you need to delete millions of outdated Orphaned Post Meta , than plugins will timeout your SQL Database.
Especially if you experiment with post plugins loops can cause very fast tausend of duplicated post and metas.This is the first try to explore and dig a bit deeper into the Developer World , not only from the code and benefit side but also to learn more about the style and thinking that build the red line thru all his work . Many times phantastic people nearly disappear online and there Blogs get abandoned . Most likely one of the Big 5 IT cooperation already hired him and no time for free plugins or Blogging .

Wp- Sweep is from the Developer Lester Chan a well known high profile WordPress Developer . The Plugin works smooth and clean following WordPress Tables and Terms as long they stay below 100.000 entry then it still works but can take extremely long and outtime your SQL Database on a shared hostThe image below show the wp sweep admin screen after cleanup .Of course before you make any change or clean up in your database dont forget the full backup . For a faster access i use a client like Sequel Pro to manage all the Databases<code>

Upgrading my OSX php to 5.5 not recommended need a upgrade to MAMP3 . Wy we dont upgrade to the new version ? Settings and custom Build for this version was a lot of work and not documented that well like i log now every change on the system that was the main reason i stuck for very long on the running MAMP 2.2 .
Since i just learn to work with brew and debug some build problems this is a little resoruce to help beginner who like compile there builds. This resource was created by experimenting with a custom MLT build. Read also the Formula Cookbook to learn more . Some note

Common Brew install messages
Even after insalling a package dont mean its available for the system if its keg-only its not linked as the system have already a version. If you whant to build with that lib or package you must include the LDFLAGS and CPFLAGS in your make file or you can try to –force linking for your compile .
keg-Only
This formula is keg-only, which means it was not symlinked into /usr/local.
OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/curl/lib
CPPFLAGS: -I/usr/local/opt/curl/include
First of all i have to mention that comping software i am very new to had just compiled ffmpeg and imagic for my Dev MAMP work field. But after got hot with image and video processing software like MLT . I just found the gorgeous branch stills2dv . Zooming probably is not the big thing but how the lib speed and slow up the pans and zooms is the best and most intuitive i have seen. Building the workfile is like writing a Text script how to zoom and Pan . Very simple if you have a bit of feeling for Pans & Zooms .
This stills2dv package have some very sweet Zoom and Pan options for still images but was build for Linux and some outdated lybs and commands made it a bit hard for me compile. for future i will note here what i change to get it work .Last but not least dropped in as i would like huge panorama images and return a video that can be shared on social media platforms like Facebook or Instagram. That as a terminal batch proces without opening any editing software.
Future idea is to create the workfile for pan zoom with a html editor.
First of all watch the video to get a impression what is the still2dv can do
First make sure you have the needed libs Installed
X11 installed
most likely this packages are already on your machine
libc gcc make libjpeg-dev libpng-dev
Some changes for the PATH to work on OSX below my make file with corrected paths. The only change was in the first lines -lXext and -lX11 made me some trouble till i installed XQuartz .
To run the Install you need also to adapt the install part since root:root doesn’t exist on osx .The install done manually in the terminal
One more change on s2d_png.c since libpng updated some commands will not work. My s2d_png.c following error found on stackoverflow
Chances are you are compiling IM with png.h from libpng-1.5.x but * Bugs png_longjmp” only exists inlibpng-1.5.x. * libpng-1.6.17 already installed
changeds2d_png.c to following . Mostly replaced the old format to the new strukture

IMPORTANT
We need XQuartz works fromOS X 10.6.3 till El Capitan , Download and install this part output the images to the window and will get started from the terminal as soon Showoutput get executed.
Since i discovered the revolution Slider iam got a big fan of the Slider even its quite heavy load but on some pages its more than worth. But the problem as long its not a part of your theme the Slider will play only in my blog content area . So i wish to play revolutions slides even in the banner area . Socalled execute revolution Shortcodes on the single blog page and even on the frontpage slider .Where i normally chose images who should rotate.
Here a view lines of code i added to the theme frontpage theme template . To clarify i use the Blip Theme and Option Tree to setup theme options and more . Blimp is not any more maintenance so any change and upgrade i have to make myself.
<?php $sliders = ot_get_option('pxg_bliv_homepage_slider'); ?>
<div class="featured-inner flexslider">
<ul class="slides">
<?php
// ALL TIME RENDER BACKGROUND IMAGE
foreach ($sliders as $key => $slider) { ?>
<li style="background-image: url('<?php echo $slider["image"] ?>')">
<?php
// IF REVOLUTION SLIDER
if (preg_match("/(?<=alias=\").*?(?=\"\])/s", $slider["title"], $result)){
$revolID = $result[0];
}
if (strpos($slider["title"],'');
// RENDER ANY SHORTCODE WE FOUND IN TITEL
}elseif(strpos( $slider["title"], '[' ) !== false){
echo do_shortcode($slider["title"]);
// ELSE DAFULT SLider
}else{ ?>
<div class="container">
<span class="sub-title"><?php echo $slider["description"] ?></span>
<span class="title"><?php echo $slider["title"] ?></span>
</div>
<?php } ?>
</li>
<?php } ?>
</ul>
</div>
To explain the code , we check if a revolution slider shortcode is in the Title if so we extract the parameter and execute with do_shortcode the Slider . After we look if any other shortcode is in the Title if so we execute that . In my case i use iframe Advanced and sometime i would like to render some fancy D3 animation or Odyssey.js in the header. If No shortcode is found we render the default images set in the theme Settings.
this is probably not 100% foolproof but for now it works quite well. Code above is for the front-page.php but its nearly the same for the single blog post page . Below how it looks like from a test blog. header cover is with revolution slider and fully anim able from the backend . The Slider loads beforehand the default image still the Big Slider is finally loaded. This is nothing that make since for fast pages but since i seperate Blog and Main page it will not affect the blog.
Just wrote this down to remember all the little changes for later, or if i change the theme one day. Formating of the code need to be changed to be a little bit clearer

A short overview how to install MLT on a Mac OSX since most hints are for Linux user and the path is not that simple for a non Linux User its a work in progress with a long way to debug the missing GTK . Without GTK we will not get any Text over the Videos as all other modules will fail to render Text. These is a long journey to compile MLT and all needed packages on a OSX 10.6 with brew . I have to mention here that iam a total Unix nop and mostly i log the process here to repeat the same on a second framework or other versions. Why i document all steps and possible errors in that details ? At the moment i run my dev MAC on Snow Leopard the same procedure i will need to repeat on upgrade to El Captain and hopefully this blog post helps a bit. Additional quote new in compiling software so its a learning procedure log. Pleas keep in mind iam just a beginner with compiling software so probably they are better ways.
What is MLT ?
An open source multimedia framework, designed and developed for television broadcasting. For Processing Video Effect a very open plugin architecture make it easy to extend it . Probably the most powerful Multimedia Framework you can find with a very aktive Developer ! Kdenlive is only a GUI. All video processing is done by MLT. Recommended if you want to learn MLT is Shotcast APP a guy interface for MLT from the same developer.
Need the MLT with ffmpeg to use for some movie generation via php . The first MLT install was quite smooth except that i don’t care to much about some missing libys and additional sound libs what result in a fail of text rendering on video. MLT Framework compiled from Source.
FFMpeg and IMAGEemagick was installed already and working on the MAMP environment using 10.6 Snow Leopard xcode X11: 2.3.6 => /usr/X11
In my case i use Homebrew for most packages , the mltframeworks describe how to process with macports what i don’t want to install again . First of all check that your brew is updated and correct working. Keep in mind that some make prozess take very long ! Best place to start was the kdenlive help page even it was for linux.
Why Homebrew installs into /usr/local ? Because its easy and save.
Packages updated keep all fresh
Fix all errors you can find. Thats sound easy but will be the most important part. If the brew upgrade process fail or get stuck just execute one by one formula by brew update
brew update & brew upgrade
brew doctor
Check the needed dependencies for MLT , below a list with marked Ok for brew formulas and NoP for none. UPDATE brew now offer a MLT formula but with no config option and default is with -disable-gtk what means no text overlay 🙁
The downside it will install MLT without GTK so no text over video rendering engine. even if you change the config flags gtk it will not compile without some errors. But a good starting point to experiment with MLT.
If something runs wrong
brew install --verbose --debug mlt
Required packages for a Linux install, since the devel Dev versions are not available in a OSX we need compile them from source.To compile anything on OS X, you’ll need to have XCode .
Installing X11 : In OS X 10.8 Mountain Lion and later, X11 is not provided anymore. You need to install XQuartz, from http://xquartz.macosforge.org/landing/. In earlier version of OS X, this is not stricly necessary, but recommended as XQuartz is more robust and updated that the system-provided X11.
In our case GTK and Cairo can compiled with X11 or without ,default is without that will brake our build for MLT.One big problem compiling MLT with GTK was that it get the wrong libs. To force the build process to use our own gtk+ we place the PATH for GTK before the X11 PATH in our private_Bash ,Like below. How to compile gtk+ with the dev packages is excellent explained in Building GTK-OSX this was the only source who describe how to compile gtk -dev what is needed for MLT with GTK on OSX. Mac OSX (Snow Leopard in this case) already ships with many libs (or a own version of it). Brew will install this as keg-only to use it in your build you have to set the the CXXFLAGS LDFLAGS in your make file.
Highly recommended Audio Packages -dev builds are needed for compiling (Linux) libsox-dev libjack-dev ladspa-sdk
Tools for building MLT needed: cmake , git ,subversion , pkg-config ,autoconf default install dir for packages will be /usr/local/include/
MLT GTK+ Install problems
It seems that many people have the same problem here and here if you are not a soft pro. This post brought me to the right path general GTK+ problems read more about troubleshooting GTK
Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System (via both Xlib and XCB), Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB. Cairo formula
Pango : Internationalized text layout and rendering library Install Pango
brew install pango
GTK2 Why is this package not being found ?
GTK+ : This was quite the hardest nuts, MLT never found the gtk2 package respond after config with . Important remove any trace of fink and macport reported by brew doctor else it will brake your build since its a jhbuild Mixing Fink or MacPorts and GTK-OSX will fail.

What is GTK ? Gtk is a unix graphical framework originally designed to run on Unix systems with X-Windows but it provides multiple backends including one for OS X’s Quartz graphics engine, so it can be built to run on OS X without enabling the X11 subsystem.
tray install GTK 2.0 first with brew but still the development devels are missing
brew install gtk+
Debugging GTK2
In my case gtk2 never get recognsied by MLT ./config .
1. Check the config Flags for GTK, the first gives the option to link the libs, the second the paths; I usually use something like
To debug the installer you can add following into the gdk build configure script located in the melt0.8.9/src/modules/gtk2 . add the debugger for pkg-config around line 24 where it chose to brake your GTK . It will output all the single steps and paths to make it easy to find the bottle neck.
pkg-config $pkgconfig_prefix gtk+-2.0 --debug
FLAGS output
Package libpng16 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libpng16.pc’
to the PKG_CONFIG_PATH environment variable
Package ‘libpng16’, required by ‘gdk-pixbuf-2.0’, not found
install QT important need some quite long time 120 min
brew install qt
SOX SoX – Sound eXchange apply various effects and convert sound formats. Sound Modules
Install Sox
brew install sox
swfdec : Flash modul no brew formula last update 2008 version 0.8 SWFDEC is also as binary available see FAQ . Mltframework have a own fork swfdec 2012 install swfdec
Just realize that my FFMPEG version was very old to upate your ffmpeg runn following terminal commands. recommended is to run clean uninstall first. Dont forget to link if any old parts are still there the terminal ask to remove it. Like an old ffplay
brew uninstall ffmpeg
brew install ffmpeg
brew link ffmpeg
MLT Config Option
To understand the MLT build script its build with jhbuild . Since we need the full developer envoirment for GTK we build our own GTK build for OSX this guranti us that we have a mostly complete GTK developer Enable GPL is needed to activate all GPL modules –enable-gpl . Check the MLT Dependencies
Prefix MLT –prefix=/usr
Additional we can add prefix for our GTK2 –prefix
Compile and Install MLT for Mac OSX
Thats the most easy part at least on the first run …
git clone git://github.com/mltframework/mlt.git
