FFmpeg ExamplesIn this section, we will look at some basic examples of how to use the FFmpeg utility
Basic conversionWhen 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:
Convert an audio file from mp3 to OGG:ffmpeg -i input.mp4 output.webm
ffmpeg -i input.mp3 output.ogg
Specifying codecsWhen 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
