simple app to cut multimedia file into pieces and merge them

• nodejs >= 8
• ffmpeg
• multimedia file: mp3, wav, mp4, vob, etc

If you have a audio file called /foo/bar/source.mp3 and you just need these intervals:

• from 00:20 to 00:25
• from 00:25 to 00:30
• from 00:30 to 00:35

And the output file should be: /foo/baz/output.mp3, execute the following command

node app.js "00:20->00:25 00:25->00:30 00:30->00:35" "/foo/bar/source.mp3" "/foo/baz/output.mp3"

After that you will have a new file /foo/baz/output.mp3 which is the union of all intervals.

• Buffer to string
• Use arguments parser
