Welcome to OpenCORE OpenCORE is the multimedia framework of Android originally contributed by PacketVideo. It provides an extensible framework for multimedia rendering and authoring and video telephony (3G-324M). The following is a brief overview of the directory structure to make it easier to understand the organization. Below is a list of the top-level directories along with a brief note about the contents. __ |-- android [Contains the components the interface OpenCORE with | other parts of Android] |-- baselibs [Contains basic libraries for data containers, MIME string | handling, messaging across thread boundaries, etc] |-- build_config [Contains top-level build files used to build the libraries | outside of Android] |-- codecs_v2 [Contains the implementations of PV's audio and video | codecs as well as the OpenMax IL interface layer] |-- doc [Contains the documentation required to interface with | OpenCORE] |-- engines [Contains the implementation of the player and author | engines as well as a utility for metadata.] |-- extern_libs_v2 [Contains 3rd-party libraries used by OpenCORE. | Currently this directory contains header files | defining the Khronos OpenMax IL interface] |-- extern_tools_v2 [Contains 3rd-party tools used to build OpenCORE | indpendently of the Android build system] |-- fileformats [Contains the libraries for parsing a variety of | fileformats including mp4/3gp,mp3,wav,aac.] |-- modules [Contains build files for aggregating low-level libraries] |-- nodes [Contains the OpenCORE framework "nodes", which is | the abstraction used to implement independent multimedia | processing units that can be connected in a flow graph] |-- oscl [This is the Operating System Compatibility Layer which | provides the mapping OS APIs as well as some basic | data structures and utilities.] |-- protocols [Contains parsers and composers for a variety of network | protocols such as HTTP, RTP/RTCP, RTSP, and SDP] |-- pvmi [Contains fundamental definitions that make up OpenCORE. | The directory name is an abbreviation of PacketVideo | Multimedia Infrastructure] |-- tools_v2 [Contains tools used to build the libraries outside of Android] Within each library the following directory structure, with a few exceptions, to organize the files: __ |-- build |-- make <- makefile to build outside of Android is here |-- doc <- directory for any documentation specific to this lib |-- include <- header files that are part of the external interface go here |-- src <- source and internal header files of the library |-- test <- test code (follows a similar structure. |-- build |-- make |-- include |-- src
