Use of FFmpeg
Here we will explain some of the primary examples of FFmpeg
uses.
Basic Conversion
The good thing with FFmpeg is when you are going to convert
of video or audio file from one format to another you no need
to specify input or output format, It will automatically detect
input file format, and for the output format, it will take from
the file name extension.
Example 1 – Convert a video file from mp4 to webm:
$ ffmpeg –I input.mp4 output.webm
Example 2 – Convert an audio file from mp3 to ogg:
$ ffmpeg –I input.mp3 output.ogg

8. LINUXCONCEPT
Specifying codecs
You can specify the codecs at the time of file conversion using
FFmpeg using –c option. It can be the name of supported
encoder/decoder or a unique value copy which simply copies
the input stream.
Example 1 – you can convert a video file from mp4 format to
webm using video codec “libvpx” and audio codec “libvorbis”
using following command:
$ ffmpeg –I input.mp4 –c:v libvpx –c:a libvorbis
output.webm
Example 2 – You can convert an audio file from mp3 format to
ogg encoded with the codec “libopus”.
$ ffmpeg –I input.mp3 –c:a libopus output.ogg
Conclusion
Now, you are ready to install FFmpeg on Ubuntu 21.04 and
