FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video.

All you need to do is just install one more repository:
http://rpmfusion.org/Configuration

wget http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm
sudo rpm -Uhv rpmfusion-free-release-6-1.noarch.rpm
wget http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm
sudo rpm -Uhv rpmfusion-nonfree-release-6-1.noarch.rpm
sudo yum install ffmpeg

Done.
ffmpeg version 0.10.15 Copyright (c) 2000-2014 the FFmpeg developers built on Aug 30 2014 15:49:19 with gcc 4.4.7 20120313 (Red Hat 4.4.7-3)

Obviously there is no fun with FFmpeg if you don’t have anything to convert. I needed to crop vertical videos from iPad to square – Vine like format.

Pretty easy but annoying task. Especially when you want to send email using specific SMTP server, or from GMAIL using SSL or add some attachment, or send RAW emails. Solution is there – mailsend . Extremely simple command line tool for Linux, Mac OS X and even Windows ;). Compile / download binary and you can enjoy freedom of sending emails from command line.

CentOS is pretty new, and some default stuff is just missing. Like NFS suport out of the box.

We have to install package called nfs-utils

yum -y install nfs-utils

we can mount using standard mount 192.168.1.15:/c/share

mount -a 

to make it parmament

edit /etc/fstab

192.168.1.15:/c/share /mnt/nfs nfs defaults 0 0

This tutorial just updated version of my previous one . This time we are going to install newer version of apache (httpd 2.4), PHP 5.4 but as a PHP-FPM . Instructions are pretty simple. You can just copy and paste command to get working stack in less then 15 minutes.

What you can learn from it? How to install Apache 2.4 and PHP 5.4, how to enable and APC, and how to install HTTPS on your server, with purchasing SSL certificate.
