  • A newly deployed Vultr CentOS 6 or CentOS 7 server instance.
  • A sudo user.

Step 1: Update the system

ধাপ 1: সিস্টেম আপডেট করুন
 
sudo yum install epel-release -y
sudo yum update -y
sudo shutdown -r now
পদক্ষেপ 2: নক্স ডক্সটপ YUM repo ইনস্টল করুন
 

There are no official FFmpeg rpm packages for CentOS for now. Instead, you can use a 3rd-party YUM repo, Nux Dextop, to finish the job.

On CentOS 7, you can install the Nux Dextop YUM repo with the following commands:

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

For CentOS 6, you need to install another release:

sudo rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm

Step 3: Install FFmpeg and FFmpeg development packages

পদক্ষেপ 3: FFmpeg এবং FFmpeg ডেভেলপমেন্ট প্যাকেজগুলি ইনস্টল করুন
 
sudo yum install ffmpeg ffmpeg-devel -y

Step 4: Test drive

ধাপ 4: টেস্ট ড্রাইভ
 

1) Confirm the installation of FFmpeg:

ffmpeg

This command provides detailed info about FFmpeg installed on your system. At the time of writing, the version of FFmpeg installed using Nux dextop is 2.6.8.

If you want to learn more about FFmpeg, input:

ffmpeg -h

2) Convert an mp3 audio file to an ogg audio file.

You need to determine the appropriate parameters when using FFmpeg. For example, you can convert an mp3 file to an ogg file using the following commands:

cd
wget https://archive.org/download/MLKDream/MLKDream_64kb.mp3
ffmpeg -i MLKDream_64kb.mp3 -c:a libvorbis -q:a 4 MLKDream_64kb.ogg

3) Convert an flv video file to an mp4 video file.

Here is an example of lossless conversion from flv to mp4:

cd
wget https://archive.org/download/beeenieilp/beeen.flv
ffmpeg -i beeen.flv -y -vcodec copy -acodec copy beeen.mp4
