Codem

Codem is designed to be flexible, scalable and robust. Flexible, since it's easy to extend, scalable, since it's easy to add more Transcoders, and robust because each part of the system acts independently of the others. Codem is built using open source technologies that have proven their value in various production environments.

Codem consists of two separate packages which communicate via a JSON api. The Scheduler is built in Ruby on Rails and deals with scheduling and handling of jobs. The Transcoder is built in NodeJS and handles the actual transcoding of videos through ffmpeg. Both packages can be used independently and provide a simple JSON api themselves. In case you need more transcoding power, it's easy to set up more Transcoder instances. Just set up another Transcoder, add it to the Scheduler, and it will start to accept jobs.
