| 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 |
