Abstract

The project Ginga Code Development Network (GingaCDN) was created to implement a reference version of Ginga, the Brazilian Digital Television System (SBTVD) middleware, supporting the declarative GingaNCL and the procedural GingaJ environments in the same middleware. To reach that, a common core is being implemented, named Ginga Common Core (GingaCC). One of the main components of the GingaCC is the one responsible to decode audio and video streams, called Media Processing. In this work, two Media Processing implementations using libVLC and Xine graphical libraries are investigated. Performance tests and results of both Media Processing implementations running in two different desktop architectures are discussed.
