In this paper, we introduce the Just-In-Time Adaptive Decoder Engine (Jade) project, which is shipped as part of the Open RVC-CAL Compiler (Orcc) project. Orcc provides a set of open-source software tools for managing decoders standardized within MPEG by the Reconfigurable Video Coding (RVC) experts. In this framework, Jade acts as a Virtual Machine for any decoder description that uses the MPEG RVC paradigm. Jade dynamically generates a native decoder representation suitable for X86, ARM and CELL platforms with a possibility of exploiting multi-core CPUs. Thus, according to the MPEG RVC decoder description coupled with a video coded stream, Jade can create, configure and re-configure video decompression algorithms adapting to the video content.
