More information about FFmpeg ?

FFMPEG is one of the most leading multimedia frameworks. It easily decodes and encodes images and videos.

Also, it supports almost all audio and video formats. Moreover, it supports all streaming protocols as well.

For instance, to convert an MP3 file to an OGG file we run the below command:

ffmpeg -i input.mp3 output.ogg

And to convert MP4 to WebM we run the below command:

ffmpeg -i input.mp4 output.webm

How to install FFmpeg on CentOS ?

To install FFMPEG in CentOS, follow the process outlined below.

1. Updating the system

Initially, we update the system using the command:

sudo yum update -y
sudo shutdown -r now

2. Enabling the Nux repository

Actually, there are no FFMPEG rpm packages for CentOS. Instead, we can use any third-party YUM repo like NUX Dextop for that.

Nux repository depends on the EPEL software repository. So, to enable it we run the below command:

sudo yum install epel-release -y

Then, we import the GPG key and install the NUX repo. For that, we run the below command to import GPG key:

sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro

Then, we install the NUX dextop release repo using the below command:

sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

3. Install FFmpeg

Next, we install FFMPEG and FFMPEG packages using the command:

sudo yum install ffmpeg ffmpeg-devel -y

4. Testing FFmpeg

Finally, we test the installation of FFMPEG using the command:

ffmpeg

Troubleshooting some Common errors with FFmpeg install CentOS ?

Recently, one of our customers approached us telling us that he was not able to install FFmpeg in his server CentOS 7.

The customer used the below command for installing FFMPEG:

yum install ffmpeg -y

But he received an error relating to some missing libraries in the server.

The error was as below:

Error: Package: libva-1.0.16-3.el6.x86_64 (linuxtech)
Requires: libudev.so.0()(64bit)
Error: Package: libavdevice-2.6.8-3.el7.nux.x86_64 (forensics)
Requires: libopenal.so.1()(64bit)
Error: Package: ffmpeg-libs-2.6.8-3.el7.nux.x86_64 (forensics)
Requires: libass.so.5()(64bit)

Here, the command which the customer was using was all correct. 

However, those libraries were missing in the server. And we can install those libraries from EPEL repository.

So, our Support Experts suggested installing it using the below command:

sudo yum install epel-release

And then run the below commands to import the GPG key and then install the NUX desktop:

sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

Then lastly, run yum, enabling the EPEL and Nux desktop repo, and install FFmpeg:

yum -y --enablerepo=epel,nux-dextop install ffmpeg

Finally, this fixed the error.
