FFmpeg Examples

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

When converting audio and video files with 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:
ffmpeg -i input.mp4 output.webm
  • Convert an audio file from mp3 to ogg:
ffmpeg -i input.mp3 output.ogg

Specifying codecs

When converting files, use the -c option to specify the codecs. It can be a 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:
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.
ffmpeg -i input.mp3 -c:a libopus output.ogg

FFmpeg is a great multimedia software, the list is full of what you can do with the software and we have only mentioned a few of the dozens. Overall, this is a simple, lightweight program and simple to operate. In our testing, we had no issues converting our files, and it was done fairly quickly and efficiently.
