A port of the powerful audio/video encoding/decoding library FFmpeg to libretro. This core allows playback of a variety of audio and video formats, with a fancy audio visualizer and the ability to do interframe blending for smoother scrolling of non-native framerates.
This is a project based on libretro FFmpeg core used by Retroarch. Since the original core is included inside the main Retroarch project, it is not feasible to directly fork the same. I've reorganized the file and folder structure and performed some code refactoring to allow its isolation into a sepparated new project.

just execute make or make DEBUG=1 if you want a more verbose execution
This core has been tested only in Raspberry Pi devices using a development version of RePlay OS
