The Brazilian digital TV system, known as International System for Digital Television (ISDTV) specifies the Ginga middleware, supporting both the declarative Ginga-NCL and the procedural Ginga-J subsystems. To make feasible the integration of these two disjoint sub-systems, it was specified the Ginga Common Core (GingaCC), being developed by the Ginga Code Development Network (GingaCDN) project. The GingaCC is composed by 13 components, including a video and audio decoding one, named Media Processing. This paper investigates two media processing implementations for the GingaCC using two different decoding open-source libraries, libVLC and xine-lib, a component model named FlexCM, and the CppUnit test framework. In order to evaluate these implementations, performance tests are executed and a discussion regarding memory usage and CPU load are carried out.
