  1. Installing FFmpeg on CentOS 7​

    FFmpeg is not available in CentOS 7 core repositories. You can choose to or to install it via yum from a third-party Yum repository.

    We’ll go with the second option and install from the RPM Fusion repository:
    1. The RPM Fusion repository depends on the software repository. If the EPEL is not enabled on your system, enable it by typing:
    2. Kod:
      sudo yum install epel-release
    3. Next, enable the RPM Fusion repository by :
    4. Kod:
      sudo yum localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-7.noarch.rpm
    5. Once the repository is enabled, install FFmpeg:
      Kod:
      sudo yum install ffmpeg ffmpeg-devel
    6. Verify the FFmpeg installation by checking its version:
      Kod:
      ffmpeg -version
      At the time of writing this article, the current version of FFmpeg available in the RPM Fusion repository is 3.4.7:
      ffmpeg version 3.4.7 Copyright (c) 2000-2019 the FFmpeg developers
      built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-39)
      ...Copy
      That’s it. FFmpeg has been installed on your CentOS machine and you can start using it.

    FFmpeg Examples​

    In this section, we will look at some basic examples on how to use the ffmpeg utility.

    Basic conversion​

    When converting audio and video files using ffmpeg, you do not have to specify the input and output formats. The input file format is auto-detected, and the output format is guessed from the file extension.
    • Convert a video file from mp4 to webm:
      Kod:
      ffmpeg -i input.mp4 output.webm
    • Convert an audio file from mp3 to ogg:
      Kod:
      ffmpeg -i input.mp3 output.ogg
      Specifying codecs
    You can specify the codecs you want to use with the -c option. The codec can be the name of any supported decoder/encoder or a special value copy that simply copies the input stream.
    • Convert a video file from mp4 to webm using the libvpx video codec and libvorbis audio codec:
      Kod:
      ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm
    • Convert an audio file from mp3 to ogg encoded with the libopus codec.
      Kod:
      ffmpeg -i input.mp3 -c:a libopus output.ogg
