Contest Brief

I need a script in bash to run on a headless Trusty server that will normalise the audio for multiple .mp4 files downloaded from YouTube.

Downloads by Firefox plugin at https://github.com/gantt/downloadyoutube

- "Download YouTube Videos as MP4 1.7.25 by ialc"

.mp4's Will be 360p or 720p


** NOTE, there is no interaction with firefox, nor does file transfer need to be considered, I am only stating where these have come from as background information. It may be assumed the .mp4 files are in some arbitrary directory. Recursion into sub-folders is not required, nor is filename matching, just do them all. Ideally new files shoud be created, but how you do this (switches or target dir) is up to you,

Difficulty : should not use ffmpeg, but libav or other tools actually in the Trusty repositories.

I will supply sample .mp4 files with low audio levels.

I can also supply a temporary non-sudoer SSH login to an arbitrary development server if required.

Time 48 hours pay $30.
