OpenCORE_OverView

学习下opencore,下面是翻译的官方文档:

opencore是Android系统下的多媒体框架,最初由PacketVideo维护,它为multimedia rendering,authoring,以及VideoTelephony(3G-324M)提供一套可扩展的框架。

下面是opencore的目录结构:
  |-- 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.
  |                              PacketVideo Multimedia Infrastructure]
  |-- tools_v2         [Contains tools used to build the libraries outside of Android]


|-- 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
