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

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
