Example of Using FFmpeg in Rocky Linux 8
In this section, we will look at some basic examples of how to use the utility
When converting audio and video files with ffmpeg, you don’t need to specify input and output formats. The input file format is detected automatically, and the output format is guessed based on the file extension.
Convert video files from mp4 to webm:
ffmpeg -i input.mp4 output.webm
Convert audio files from mp3 to ogg:
ffmpeg -i input.mp3 output.ogg
Using a codec
When converting files, you can specify the codec you want to use with the options
-c. The codec can be the name of each supported decoder/encoder or the value
copy which only copies the input stream.
Convert video files 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 audio files from mp3 to ogg encoded with libopus codec.
ffmpeg -i input.mp3 -c:a libopus output.ogg
