FFmpeg is a popular open source solution to record, convert, and stream audio and video, which is widely used in all kinds of online streaming services.
In this article, I will show you how to install FFmpeg on a CentOS 6/7 server.
sudo yum install epel-release -y sudo yum update -y sudo shutdown -r now 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 sudo yum install ffmpeg ffmpeg-devel -y 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.

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 That concludes our tutorial. Thank you for reading.
