How to install FFmpeg and ffmpeg-php on CentOS Easily

FFmpeg is an amazing collection of open-source tools that can record and stream video and audio. However, it can also transcode video and audio (convert the files to different formats), and that is what has me so excited. There’s also a great PHP package called ffmpeg-phpthat allows for easy use of FFmpeg from inside PHP scripts. Today, I’m going to see if I can’t help you get both of these set up on your system.

Admittedly, it’s been a while since I’ve tried to install FFmpeg, about two years. I recently thought up some ideas on how I’d like to use FFmpeg, so I thought it was time to give it a try yet again. Today, I’m proud to say that installing FFmpeg is so much easier to install compared to the past, that I dare say it’s simple.

Here is my experience with installing FFmpeg on my server and how to fix the pitfalls that I encountered.


Note that I did all the following steps on a CentOS server. The specific version is CentOS x64 6.7.

These instructions can work for other distros with little or no modifications, but some distros will be completely different. For example, theDAG RPM Repository that I’m using (more info below) has support for the following distros: Red Hat Enterprise Linux, Fedora Core, Yellow Dog Linux, Aurora Linux, CentOS, Scientific Linux (they really need to get a verified SSL cert), TaoLinux, WhiteBox Linux, Lineox, andBLAG. Other distros will need to use a different repository.

If you successfully get FFmpeg running on another distro, please comment your changes here and I’ll update the post (and make sure you get credit of course).

Also note that I experienced some bumps in the road while installing everything. While many of you may not experience these issues, I found it important to document these problems and how I fixed them in case you encounter them.


The first thing that you need to do is set up the DAG repository. This repository is an actively-maintained repository that provides a staggering number of packages with current or near current builds. Adding this repository is a great way to run the latest offerings of many packages.

Adding the DAG repository is simple. I’m using yum, so I did the following to add the repository:

  1. Create and open a new file called /etc/yum.repos.d/dag.repo. I ran “vi /etc/yum.repos.d/dag.repo“.
  2. Add the following text to the file:
    name=DAG RPM Repository
  3. Finally, save and close the file.

In order to successfully use the DAG repository with tools such as yum, you need to add DAG’s GPG key. Failure to do so will result in an error like the following:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 6b8d79e6
Public key for faac.x86_64.1.26-1.el5.rf.rpm is not installed

In order to add the GPG key for DAG, run the following:

rpm --import

The DAG: Frequently Asked Questions page has additional instructions on how to get the repository loaded and working on your distro.

Now that DAG is setup, it’s a good idea to update all your packages.

yum update

Depending on the packages you currently have installed, this could potentially upgrade, install, or replace numerous packages that may or may not be very important to you. Make sure you carefully look through that list and do any necessary preparations before telling yum that it can go ahead.

For example, yum told me that it was going to replace my current MySQL interface library for Perl with a new one. I added to my check list a note to verify that my Perl code functioned correctly after the install.

I ran into another hitch when I told yum to go ahead with the update. It informed me that my current version of Subversion conflicted with the new version it wanted to install. When this happens, you need to remove the old package before proceeding. This time, I made backups of all of my repositories and my /etc/sysconfig/svnserve file before proceeding just in case. I then removed Subversion “yum remove subversion“, ran the update process “yum update“, and installed Subversion again “yum install subversion“.

Installing – FFmpeg

Now you are ready to install FFmpeg with yum. I wanted to install all the available FFmpeg packages, so I first asked yum what was available.

yum search ffmpeg

Searching through the results, I found that three packages need to be installed: ffmpeg, ffmpeg-devel, and ffmpeg-libpostproc.

yum install ffmpeg ffmpeg-devel ffmpeg-libpostproc

Note: If you install ffmpeg-libpostproc, the entire FFmpeg software library changes from the LGPL license to the GPL license.

After a couple of minutes, the packages and the packages that they depend on were installed.

I simply ran “ffmpeg” from the command line, and I took the lack of threatening error or warning messages as a good sign that things were working.

Preparing for ffmpeg-php

I often work with programs through command line calls in code, but I wanted something more robust this time, so I looked around and foundffmpeg-php. Based on the API, it looks to be a great tool to interface PHP and FFmpeg.

There are four things that are required to successfully install and run ffmpeg-php; they are:

  • ffmpeg-0.4.9_pre1 or higher
  • php-4.3.0 or higher
  • gd-2.0 or higher
  • php-devel

PHP and FFmpeg should be good to go since at the time of this writing, DAG has PHP version 5.1.6 and FFmpeg version 0.4.9. GD and php-devel can be easily installed by running the following yum command:

yum install php-gd php-devel

In case you are wondering what php-devel is for, it installs the phpize program which is used to install ffmpeg-php.

Installing ffmpeg-php

Now we are ready to install ffmpeg-php. This can be done in six easy steps:

  1. Download the latest ffmpeg-php release
  2. Extract the archive:
    tar -xjf ffmpeg-php-X.x.x.tbz2
  3. cd ffmpeg-php-X.x.x/
  4. phpize
  5. ./configure && make
  6. sudo make install

Finishing Thoughts

This may seem like a lot of work when I earlier described this process as “simple,” but trust me that this is a thousand times easier than when I first tried installing FFmpeg. I think I spent three hours working on installing FFmpeg just to find out that it didn’t work the first time I tried.

Time and time again, package management has proven to be an extremely powerful tool. While I know the value of manually configuring and compiling code, the ease of simply using a package manager can reduce the time needed to install and manage software from hours or days to minutes.

I’m glad to see that FFmpeg has benefited from the use of these package managers and great repositories like the DAG RPM Repository.

Install Transmission Client to RHEL / CentOS 6

Torrent Guide – Install Transmission Client to RHEL / CentOS 6


Transmission Bittorrent Client

Transmission is an open source and extremely lightweight Bittorrent client. It is available for any OS and comes with it’s own GUI interface.

Although Transmission is not as popular as rTorrent/ruTorrent for seedboxes, it is still a strong solid choice as it does not require a web server to be deployed on the OS and has a light memory footprint allowing for it to run in very-low ram VPS environments.

Installing Transmission-BT to CentOS 6

For this guide I will be using CentOS 6, but any RHEL distro should work with similar commands.

Transmission can be installed quite easily through the repositories, however it is not part of the default Red Hat repositories. First we will need to install the EPEL repository to our server:

You can find the lastest EPEL repositories here:

For simplicity sake you can always just following my guide with version as of time of this writing, as it will be updated when you do an upgrade anyways.

rpm -Uvh epel-release-6-8.noarch.rpm

Now with this repository added we can install Transmission via yum

yum -y update
yum -y install transmission transmission-daemon

Then start the process:

service transmission-daemon start

Test Transmission

Transmission uses port 9091 by default, try it now using your server’s IP or FQDN.

You will either see Transmission load, or you will see an error like this:


The reason for this error is because Transmission is setup by default to only accept connections from localhost. If you get this error proceed to the next step…

Configure Transmission For Remote Access

Before we modify the configuration we’ll want to stop the service. This is important!! Transmission will write it’s setting files on shutdown, so if we edit the settings now and “restart” Transmission then our changes just get overwritten.

service transmission-daemon stop

Now we can make changes to the settings.json file. Transmission will automatically write it’s config to the user’s home directory. By default the daemon process will be using “Transmission” user which is set to /var/lib/transmission rather then using the /home folders.

If you have trouble finding your settings.json you can always use the findcommand:

find / -name settings.json

Edit the settings.json file once you’ve located it:

nano /var/lib/transmission/.config/transmission/settings.json

Find the following lines:

    "rpc-whitelist": "",
    "rpc-whitelist-enabled": true,

Change this according to your preferences. When a “White List” is set it means only those IP addresses can access the software. If you want to use the White List then set the appropriate IP addresses here. Otherwise we can just set the whitelist to false like so:

    "rpc-whitelist": "",
    "rpc-whitelist-enabled": false,

Start our service back up:

service transmission-daemon start

And test:



How to install ffmpeg, ffmpeg-php on CentOS 6/7 (Cpanel Server)


For EL6:

rpm -Uvh
rpm -Uvh

Install FFMpeg from ATRPMS Repository:

yum -y install ffmpeg ffmpeg-devel

How to check if FFMPEG is working?

Verify the ffmpeg version:

ffmpeg -version
[root@centos:~]ffmpeg -version
ffmpeg version 2.2.1
built on Apr 13 2014 13:00:18 with gcc 4.4.6 (GCC) 20120305 (Red Hat 4.4.6-4)

libavcodec     55. 52.102 / 55. 52.102
libavformat    55. 33.100 / 55. 33.100
libavdevice    55. 10.100 / 55. 10.100
libavfilter     4.  2.100 /  4.  2.100
libswscale      2.  5.102 /  2.  5.102
libswresample   0. 18.100 /  0. 18.100
libpostproc    52.  3.100 / 52.  3.100

Check the supported formats:

ffmpeg -formats

Test converting videos. Here’s an example from mp4 to h264:

cd /usr/local/src
ffmpeg -i Woodstock_Festival_Trailer.avi -vcodec libx264 Woodstock_Festival_Trailer-H264.avi

After done, you should see the new H264 file:

-rw-r--r-- 1 root root 20M May 4 2006 Woodstock_Festival_Trailer.avi
-rw-r--r-- 1 root root 15M Jan 30 10:01 Woodstock_Festival_Trailer-H264.avi

How can I work with ffmpeg using PHP?

Simple.  Just install php-ffmpeg extension. First, install REMI repo in order to get your php-ffmpeg package as below:

Let’s download the RPM file for CentOS 5.x and CentOS 6.x:

EPEL repo for  Centos 5.x

rpm -Uvh epel-release-5*.rpm

EPEL repo for Centos 6.x

rpm -Uvh  epel-release-6*.rpm

EPEL repo for Centos 7.x

rpm -Uvh  epel-release-6*.rpm

That command will install the EPEL repo inside your /etc/yum.repos.d directory.


Manually, install FFmpeg-Php
        cd /usr/local/src
        tar jxvf ffmpeg-php-0.6.0.tbz2
        cd ffmpeg-php-0.6.0
If you get (error make: *** [ffmpeg_frame.lo] Error 1) do this commands.
sed -i 's/PIX_FMT_RGBA32/PIX_FMT_RGB32/g' ffmpeg_frame.c
 vi ffmpeg_frame.c
Then rerun "./configure && make" and if all went fine make install make install If no error skil to step 5. Step 5. Now adding to php.ini echo '' >> /usr/local/lib/php.ini Step 6. Now test php with ffmpeg php -r 'phpinfo();' | grep ffmpeg

-i | grep ffmpeg -i

ffmpeg-php version => 0.7.0
ffmpeg-php built on => Jan  1 2013 09:50:55
ffmpeg-php gd support  => enabled
ffmpeg libavcodec version => Lavc53.61.100
ffmpeg libavcodec license => GPL version 3 or later
ffmpeg libavformat version => Lavf53.32.100
ffmpeg libavformat license => GPL version 3 or later
ffmpeg swscaler version => SwS2.1.100
ffmpeg swscaler license => GPL version 3 or later

When you run command ./configure if you get error: configure: error: ffmpeg headers not found. Make sure ffmpeg is compiled as shared libraries using the –enable-shared option. Check some library with command:

rpm -ql ffmpeg-devel

In On CentOS 6/7 with nux-dextop installed ffmpeg-devel

locate avio.h avformat.h avcodec.h

Now  do command:

[root@centos ffmpeg-php-0.6.0]# strace -f -o /ffmpeg-strace ./configure --with-php-config=/usr/bin/php-config --with-ffmpeg=/usr --includedir=/usr/include/ffmpeg


cat /ffmpeg-strace | egrep 'avio.h|avformat.h|avcodec.h'

Looks like ffmpeg-devel installed headers at

  • /usr/include/ffmpeg/libavcodec/avcodec.h
  • /usr/include/ffmpeg/libavfilter/avcodec.h
  • /usr/include/ffmpeg/libavformat/libavformat.h
  • /usr/include/ffmpeg/libavformat/avio.h

Problem is specific to avcodec.h, avformat.h, avio.h and swscale.h – so what about symlinking them

ln -s /usr/include/ffmpeg/libavcodec/avcodec.h /usr/include/ffmpeg/avcodec.h
ln -s /usr/include/ffmpeg/libavformat/libavformat.h /usr/include/ffmpeg/libavformat.h
ln -s /usr/include/ffmpeg/libavformat/libavformat.h /usr/include/ffmpeg/libavformat.h
ln -s /usr/include/ffmpeg/libswscale/swscale.h /usr/include/ffmpeg/swscale.h

Then configure and make again:

./configure && make

How To Install And Run VLC On CentOS 6/7 As Root

VLC media player (commonly known as VLC) is a portable, free and open-source, cross-platform media player and streaming media server written by the VideoLAN project. VLC media player supports many audio and video compression methods and file formats, including DVD-Video, video CD and streaming protocols. It is able to stream media over computer networks and to transcode multimedia files.

The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. Many of VLC’s codecs are provided by the libavcodec library from the FFmpeg project, but it uses mainly its own muxer and demuxers and its own protocols implementations. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and OS X by using the libdvdcss DVD decryption library.

For EL7:

Install  EPEL   from
rpm -Uvh

For EL6:

rpm -Uvh
rpm -Uvh


yum update
yum  install vlc


There are not so many ways to make VLC Player work as root, and I have found this way is very easy and fast to make VLC Player Work as root.

Let me make one thing more clear that VLC is not only media player it can do so many things and Running VLC as root is very very risky. So think many times before you run VLC as root.

I have only tested that VLC can open using root user, have not tested other features. So take a note of this.


Before starting it let me tell you that please take a backup of original VLC file so you can recover if anything worst.

Perform following steps to Run VLC Player as root



1) Install Hexedit Package for your System

[root@vps ~]# yum install hexedit

2) Now Execute Following command take backup of Original VLC Command :-

[root@vps ~]# cp -p /usr/bin/vlc /usr/bin/vlc_original_bin

3) Now Open /usr/bin/vlc into hexeditor, Execute Following command :-

[root@vps ~]# hexedit /usr/bin/vlc

4) Now Press “TAB” Key.

5) Now Press “CTRL + s” to search ASCII String.

6) In Search Box, Now Type “geteuid” and Replace it with “getppid”

7) Now Press “CTRL + x” to Save the file.

8) That’s it. Now You can Open VLC using Command and From Menu too.

Initial Settings after installing the CentOS 7

1) To change the hostname permanently, edit the following file:

sudo vi /etc/hostname


Here you can simply put the name of your system (in my case, I have assigned it CentOS-7):

centos7 (1)

After that, edit the hosts file:

sudo vi /etc/hosts

centos7 (2)

Here add the same name, that you have added in the /etc/hostname file, after

centos7 (3)

After reboot, it will display the new hostname.

2) After login to the CentOS7 server(minimal installation), you will notice that the system doesn’t have ifconfig command :

centos7 (4)

Install the net-tools package which will include ifconfig:

sudo yum install net-tools

centos7 (5)

Try the ifconfig command once again:

centos7 (6)

3) Change the default network interface name to “eth0″

CentOS7 has a default nic name as “en016…..”, as we can see in above screenshoot. To change it back to the default network device name like “ethX”, edit the grub file:

sudo vi /etc/default/grub

centos7 (7)

Search for the line “GRUB_CMDLINE_LINUX” and append the following: “net.ifnames=0 biosdevname=0

Will look like this:

GRUB_CMDLINE_LINUX=" crashkernel=auto vconsole.font=latarcyrheb-sun16 rhgb 
quiet net.ifnames=0 biosdevname=0"

centos7 (8)

Create a new configuration based on the currently running system using grub2-mkconfig command:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

centos7 (9)

Rename the interface files by renaming the file “/etc/sysconfig/network-scripts/ifcfg-en01…

sudo mv /etc/sysconfig/network-scripts/ifcfg-eno16777736 /etc/sysconfig/network-scripts/ifcfg-eth0

centos7 (10)

Reboot the system:

centos7 (11)

After reboot, check the interface name:

centos7 (12)

4) Configure the static ip on the server:

Edit the interface file under /etc/sysconfig/network-scripts/ directory:

sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0

centos7 (13)

Here is my ifcfg-eth0 file as a sample, please change it according to your requirement:


centos7 (14)

Stop and disable the NetworkManager service, because we don’t need it on the server:

sudo systemctl stop NetworkManager 
sudo systemctl disable NetworkManager

centos7 (15)

Restart the network service(Be careful, if you are connecting remotely, because you will be disconnected after issue this command):

sudo service network restart

centos7 (16)

Check the newly assigned static ip:

centos7 (17)

5) Disable IPv6:

First check that IPv6 is enabled or not:

lsmod | grep -i ipv6

centos7 (18)

Edit the grub file:

sudo vi /etc/default/grub

centos7 (19)

Search for the line “GRUB_CMDLINE_LINUX” and add the following at the beginning: “ipv6.disable=1

Will look like this:


centos7 (20)

Create a new configuration based on the currently running system using grub2-mkconfig command:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

centos7 (21)

Reboot the system:

centos7 (22)

Once again, check the IPv6 on the system:

centos7 (23)

6) EPEL repository on Centos 7

To install the EPEL repository, issue the following command:

sudo rpm -Uvh

centos7 (24)

List your new repos:

sudo yum repolist

centos7 (25)

7) Enable iptables services(instead of firewalld):

When you will try to start/restart the iptables on newly install server, will get this error:

centos7 (26)

To fix this error, install the iptables-services package:

sudo yum install iptables-services

centos7 (27)

Re-run the command to restart the iptables:

sudo service iptables restart

centos7 (28)

Hope this will help you!

How to Install the latest LEMP Stack on CentOS 6.5

In this tutorial,we’ll learn that how we can install the latest LEMP (Nginx, MySQL & PHP) Stack and it’s initial configuration on CentOS 6.5, because Base and EPEL repo are containing really old version of LEMP Stack.

Please add the required repos by using the following commands:

sudo rpm --import
sudo rpm -ivh
sudo rpm -Uvh
sudo yum repolist


We’ll have mysql55-libs conflicts with mysql-libs error, if we’ll proceed like this. To resolve this conflict, we need to issue these commands:

sudo yum install yum-plugin-replace
sudo yum replace mysql-libs --replace-with mysql55w-libs


Now, we can safely issue this command to install the latest version of Nginx, MySQL and PHP with PHP-Fpm:

sudo yum install nginx16 mysql55w mysql55w-server php55w php55w-opcache php55w-fpm


Enable Nginx, MySQL and PHP-FPM to automatically begin when the server boot:

sudo chkconfig nginx on
sudo chkconfig mysqld on
sudo chkconfig php-fpm on


Secure the PHP by editing the php.ini file:

sudo vi /etc/php.ini


Uncomment the cgi.fix_pathinfo and change it from 1 to 0:



Edit the  /etc/php-fpm.d/www.conf  file:

sudo vi /etc/php-fpm.d/www.conf


Change the user and group:

user = nginx
group = nginx


Next we need to do some modification in default nginx.conf file:

sudo vi /etc/nginx/nginx.conf


Increase the worker processes from 1 to 4:


Also delete the default server config block to make the file more concise:


Move to the /etc/nginx/conf.d/ directory:

cd /etc/nginx/conf.d/


Next, we’ll create the virtual host file for our domain (In my case it’s rbgeek.conf):

sudo vi rbgeek.conf


This is a basic virtual host config file:

server {
       listen 80;

       access_log /var/log/nginx/rbgeek_access.log main;
       error_log /var/log/nginx/rbgeek_error.log;
   location / {
       root /var/www/rbgeek;
       index index.php index.html index.htm;
   # pass the PHP scripts to FastCGI server listening on

   location ~ .php$ {
       root /var/www/rbgeek;
       fastcgi_index index.php;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       include fastcgi_params;
       fastcgi_intercept_errors on;


Finally, restart the Nginx and PHP-FPM services:

sudo service nginx restart
sudo service php-fpm restart


Create a directory structure for the website under /var/www/.If you have another preference, please update the config files accordingly:

sudo mkdir -p /var/www/rbgeek


Adjust the permission:

sudo chgrp -R nginx /var/www/rbgeek
sudo chmod g+s /var/www/rbgeek


Create a phpinfo page to verify that the php is working correctly with Nginx:

sudo vi /var/www/rbgeek/info.php


Add the following code in it:



Navigate to the site in web browser and verify that the php information is returned:


(Optional) Verify that all the packages are updated by using the code in your index page:


Hope this will help you!
