Split .avi video and .mp3 audio files in Ubuntu linux

Posted on: November 16, 2010

I am presently thinking of bringing out a collection of music which I like very much. It wont include any voice but just music. For that I mainly had two issues, first to split video files that I had in .avi format and second to split audio files that I had in .mp3 format.

For video files, I used ffmpeg utility

ffmpeg -i input.avi -ss 00:01:10 -t 00:04:45 output_file.avi

where input.avi is the file from which you want to extract the music.
-ss is the start point of the music
-t is the duration from the start time till when the music is to be extracted
output_file.avi is the file in this the extracted music will be stored.

It will be in .avi format only. If required you can also convert it into audio files.
This gave me the exact chunk of the music video that I wanted for collection.

For Audio files, I used mp3splt utility. I used its gui, mp3splt-gtk which is very easy to use.
All I need to do was select the file from which I wanted to extract music. Select two splitpoints, one for the start and second for the end. And select split button given at the top of the gui. Its as simple as that. Since this utility was available in Ubuntu Repository, I didnt have issues even with installing it
