Marchena is a media processing framework that allows queueing of media processing requests. Marchena uses a plugin API to allow easy expansion and comes by default with plugins that allow processing video, images and office documents. The plugins are called processors in Marchena and can be enabled or disabled by simply add or remove the processor jar files. Please refer to Turn The Marchena Processors On And Off page for details.

How it works

Marchena offers a web-service API where client programs can send in batches that point it to source files, define a set of services to perform on those files, and file locations to place the results in. The following class diagram shows the general structure of the batches that can be passed to the web-service.
