Here are a few commands for FFmpeg that were useful for me.

The help page for all parameters is here.

A nice tool that uses FFmpeg is Handbrake.

Get some info about a file

ffmpeg -i video.mp4  

Parameters:

• ffmpeg is the ffmpeg command :p
• -i video.mp4 specifies the input file

Extract the audio part of a video

ffmpeg -i video.mp4 -vn -acodec copy audio.m4a  

Parameters:

• -vn disables the video
• -acodec copy allows to copy the audio stream without touching it
• audio.m4a is the output file

Convert an audio file to another format

ffmpeg -i audio.m4a -acodec libmp3lame -ac 0 -ab 320k audio.mp3  

Parameters:

• -acodec libmp3lame allows to use the lame mp3 library for conversion
• -ac 2 sets the number of channels
• -ab 320k sets the bitrate

Of course, the previous command and this one can be merged for a 1 step audio extraction & conversion.
