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