} __attribute__((packed)) DATAHEADER ;
QT重點在:
Dataheader.ucType =0x 3, 0x 2, 0x 9, ox 7 //QT
Dataheader.ucType = (QT: 24 ,)
Dataheader.uiLength = sizeof(DVRFRAME_HEADER_V2);//下個frame長
ipcam:
Dataheader.ucType =' 3', '2', '9', '7' // ascii :0x33, 0x 32, 0x 39,ox 37
=============================================
DVRFRAME_HEADER_V2 //QT, hybrid
typedef struct _DVRFRAME_HEADER_V2
{
unsigned char ucVideoSystem; //NT=1;PAL=2
unsigned short usHeight; //影像高
unsigned short usWidth; //影像寬
unsigned char ucCompress:4; //0:mpeg4 1:h.264 2.jpeg 3:pcm 4:adpcm

unsigned char ucArg; //回放時之速度
unsigned char ucImageSource; //0: DVR 1:IPCam //2: audio
} __attribute__((packed)) DVRFRAME_HEADER_V2;
QT 重點:
// DVRFRAME_HEADER_V2
dvrheader.usHeight = 0; //影像高
dvrheader.usWidth = 0; //影像寬
dvrheader.ucFrameType = 5;
dvrheader.ucCh = 0;

dvrheader.ucSerial = 0;
dvrheader.ucArg = get_speed(pMobileUserClient->nAction,pMobileUserClient->nSpeed);;
dvrheader.ucPlayback = 0x80;
=============================================
例如v3 header //QT 使用
typedef struct Image_header_V3
{
unsigned int nStartCode; //FFFFFFAA
time_t tSec; //時間
unsigned int tuSec;
unsigned int nLen; //Frame 的資料長度
unsigned long long nRec_ch; //紀錄錄影當時的頻道
unsigned short nChA; //Channel number
unsigned short nChB:4; // For Video:Reaolution, For Audio:Audio Type

unsigned short nKeyframe:1; // 0: P-Frame , 1: I-Frame
unsigned short nVideosystem:1; // 0: NTSC , 1: PAL
unsigned short Capture:1; // 0: Analog , 1: IPCAM
unsigned short nRes:1; // 不使用,預設為 0
unsigned short field:2; // 不使用,預設為 3
unsigned short Reserver:4;
}__attribute__((packed)) Image_header_V3;
------------------------------------------------
int time_t int int (long long) short short
4 4 4 4 8 2 2 //占的位子大小(單位btye)
最後那個short為2byte,包含
nchB , nFrameType,nKeyframe,nVideosystem, //總和1byte
Capture,nRes,field,Reserver //總和1byte
以上是送
---------------------------------------
以下是收
如到因為little ending 所以會反過來,
如果為getshort(26)//26為起始位置
收到順序為Reserver,field,nRes,Capture,
nVideosystem,nKeyframe,nFrameType:2,nchB:4
所以: nFrameType 取為& 00 30
//30表示 0011(nVideosystem,nKeyframe,nFrameType:2)
0000(nchB)
=============================================
//fltk, iss 使用
typedef struct Image_Header_V2 {
unsigned int nStartCode; //FFFFFFAA
/*time_t*/ unsigned int tSec; //時間 unsigned int for 64-bit issue
//unsigned long long tSec; //時間 unsigned int for 64-bit issue
unsigned int tuSec;
unsigned int nLen; //Frame 的資料長度
unsigned int nRec_ch; //
