纳入话题标签：压缩解压缩

1. 解压缩函数：

int doDecodeVideo( QY_TRANSFORM * pTransform, MIS_MSGU * pMsgBuf );

mediaSdk的docode:

int doDecodeVideo_mediaSdk( QY_TRANSFORM * pTransform, int index_pMems_from1, int index_activeMems_from, MIS_MSGU * pMsgBuf );

2. 压缩解压缩都以模块的方式装载进系统，

loadCusModules();

typedef struct __cusModuleCompress_t { // 2010/04/28

MACRO_cusModuleCommon

QDC_MGR mgr;

PF_qdcInit pf_qdcInit;

PF_qdcExit pf_qdcExit;

PF_qdcGetProp pf_qdcGetProp; // 2015/10/20

PF_qdcSetProp pf_qdcSetProp; // 2016/04/09

PF_qdcGetCompressAudioCfg pf_qdcGetCompressAudioCfg;

PF_qdcGetCompressVideoCfg pf_qdcGetCompressVideoCfg;

PF_qdcInitCompressAudio pf_qdcInitCompressAudio;

PF_qdcExitCompressAudio pf_qdcExitCompressAudio;

PF_qdcCompressAudio pf_qdcCompressAudio;

PF_qdcCompressAudioRun pf_qdcCompressAudioRun; // 2016/12/05

PF_qdcInitDecompressAudio pf_qdcInitDecompressAudio;

PF_qdcExitDecompressAudio pf_qdcExitDecompressAudio;

PF_qdcDecompressAudio pf_qdcDecompressAudio;

PF_qdcDecompressAudioRun pf_qdcDecompressAudioRun; // 2016/12/05

PF_qdcInitCompressVideo pf_qdcInitCompressVideo;

PF_qdcExitCompressVideo pf_qdcExitCompressVideo;

PF_qdcCompressVideo pf_qdcCompressVideo;

PF_qdcCompressVideoRun pf_qdcCompressVideoRun; // 2014/04/02

// 2014/03/30

PF_qdcGetSpsPps pf_qdcGetSpsPps;

PF_qdcInitDecompressVideo pf_qdcInitDecompressVideo;

PF_qdcExitDecompressVideo pf_qdcExitDecompressVideo;

PF_qdcDecompressVideo pf_qdcDecompressVideo;

// 2011/12/10

PF_qdcDecompressVideoAndOutput pf_qdcDecompressVideoAndOutput;

// 2014/03/28

PF_qdcDecompressVideoRun pf_qdcDecompressVideoRun;

PF_qdcGetOutputByIndex pf_qdcGetOutputByIndex;

PF_qdcClearOutputs pf_qdcClearOutputs;

unsigned char ucbInited;

} CUS_MODULE_compress;

3. 模块可以以动态调用dll的方式加载，也可以以函数指针赋值的方式加载。

CONST_moduleType_ffmpeg就是以函数指针赋值的方式加载的
