FFmpeg is a free and open source command line tool for format conversion of multimedia files. It contains a set of shared audio and video libraries, such as libavcodec, libavformat, and libavutil.
With FFmpeg, you can convert between various video and audio formats, set the sampling rate, and adjust the video size.
In order to add a new repository and install software on the Ubuntu system, you must log in as a user with sudo privileges.
The official Ubuntu repository contains the FFmpeg package, which can be installed using the apt package manager. This is the easiest way to install FFmpeg in Ubuntu, but the version contained in the repository may be behind the latest version of FFmpeg.
At the time of writing, the current version of FFmpeg available in the Ubuntu 18.04 repository is 3.3.3. If you need to install FFmpeg 3. x. You can run the following commands.
First update the software package list and run the command sudo apt update. Next, run the command sudo apt install ffmpeg to install FFmpeg.
After the installation is completed, run the ffmpeg - version command to verify whether the software package has been correctly installed. This command will print the FFmpeg version.
You can also run the ffmpeg - encoders command to print all available FFmpeg encoders and decoders for verification. FFmpeg 3. x is now installed on your system.
sudo apt update
sudo apt install ffmpeg
ffmpeg -decoders
ffmpeg -version

Convert mp4 webm
When using ffmpeg to convert audio and video files, it is not necessary to specify input and output formats. FFmpeg automatically detects the format of the input file and guesses the output format from the file extension.
Here are two simple examples of converting video files from mp4 to webm. Convert audio files from mp3 to ogg.
ffmpeg -i input.mp4 output.webm
ffmpeg -i input.mp3 output.ogg
Specify codec
When converting files, use the - c option to specify the codec. It can be the name of any supported decoder/encoder, or it can be a special value copy that copies only the input stream.
The following example uses the libvpx video codec and the libvorbis audio codec to convert video files from mp4 to webm. Use libopus codec to convert audio files from mp3 to ogg.
ffmpeg -i input.mp4 -c:v libvpx -c:a libvorbis output.webm
ffmpeg -i input.mp3 -c:a libopus output.ogg
