1 Welcome to OpenCORE 2 3 OpenCORE is the multimedia framework of Android 4 originally contributed by PacketVideo. It provides 5 an extensible framework for multimedia rendering and 6 authoring and video telephony (3G-324M). 7 8 The following is a brief overview of the directory 9 structure to make it easier to understand the organization. 10 Below is a list of the top-level directories along with a brief 11 note about the contents. 12 13 __ 14 |-- android [Contains the components the interface OpenCORE with 15 | other parts of Android] 16 |-- baselibs [Contains basic libraries for data containers, MIME string 17 | handling, messaging across thread boundaries, etc] 18 |-- build_config [Contains top-level build files used to build the libraries 19 | outside of Android] 20 |-- codecs_v2 [Contains the implementations of PV's audio and video 21 | codecs as well as the OpenMax IL interface layer] 22 |-- doc [Contains the documentation required to interface with 23 | OpenCORE] 24 |-- engines [Contains the implementation of the player and author 25 | engines as well as a utility for metadata.] 26 |-- extern_libs_v2 [Contains 3rd-party libraries used by OpenCORE. 27 | Currently this directory contains header files 28 | defining the Khronos OpenMax IL interface] 29 |-- extern_tools_v2 [Contains 3rd-party tools used to build OpenCORE 30 | indpendently of the Android build system] 31 |-- fileformats [Contains the libraries for parsing a variety of 32 | fileformats including mp4/3gp,mp3,wav,aac.] 33 |-- modules [Contains build files for aggregating low-level libraries] 34 |-- nodes [Contains the OpenCORE framework "nodes", which is 35 | the abstraction used to implement independent multimedia 36 | processing units that can be connected in a flow graph] 37 |-- oscl [This is the Operating System Compatibility Layer which 38 | provides the mapping OS APIs as well as some basic 39 | data structures and utilities.] 40 |-- protocols [Contains parsers and composers for a variety of network 41 | protocols such as HTTP, RTP/RTCP, RTSP, and SDP] 42 |-- pvmi [Contains fundamental definitions that make up OpenCORE. 43 | The directory name is an abbreviation of PacketVideo 44 | Multimedia Infrastructure] 45 |-- tools_v2 [Contains tools used to build the libraries outside of Android] 46 47 Within each library the following directory structure, with a few exceptions, 48 to organize the files: 49 50 __ 51 |-- build 52 |-- make <- makefile to build outside of Android is here 53 |-- doc <- directory for any documentation specific to this lib 54 |-- include <- header files that are part of the external interface go here 55 |-- src <- source and internal header files of the library 56 |-- test <- test code (follows a similar structure. 57 |-- build 58 |-- make 59 |-- include 60 |-- src 61 62
