Codem-watcher

Description

Codem-watcher is a program that monitors a folder for new MP4 files and transcode the
file into multiple files each with different bitrates. The transcoding is performed by
codem-transcode. The resulting files are copied to the specified
destination folder and a SMIL file are created. These files can then be delivered
by for example a Wowza Streaming Engine.

Installation

Recommended installation procedure is to use npm:

# npm install codem-watcher

Use the -g option to install it globally

# npm install -g codem-watcher

To start the program find where ´npm´ installs your packages and this script. Then run

# /PATH/TO/PROGRAM/bin/codem-watcher
