Demuxing mp4 to m4a August 19, 2012

ffmpeg -i source.mp4 -vn -acodec copy destination.m4a

• calls up ffmpeg
• -i asks for the input file
• the input file in this case is source.mp4, change to your mp4
• -vn disables video recording, effectively ignoring the video
• -acodec asks for the audio codec
• in this case, the special value copy is given to specify that the raw codec data must be copied as is, so you know no transcoding is happening
• and finally we specify an output file, in this case destination.m4a, but you could name it whatever you’d like

ffmpeg -i inputfile.mp3 -t 30 -acodec copy outputfile.mp3

Bear in mind, once a virus is on your system, you really should be doing a reformat and clean install.
