hi all ,following is my cap link parameters
{
pCaptureInstPrm = &capturePrm.vipInst[0];
pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP0_PORTA;
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;
pCaptureInstPrm->standard = SYSTEM_STD_1080I_60;
pCaptureInstPrm->numOutput = 1;
pCaptureInstPrm->videoCaptureMode = SYSTEM_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_DISCRETE_SYNC_ACTVID_VSYNC;
pCaptureInstPrm->videoIfMode = SYSTEM_CAPT_VIDEO_IF_MODE_16BIT;
pCaptureInstPrm->inScanFormat = SYSTEM_SF_INTERLACED;
pCaptureOutPrm = &pCaptureInstPrm->outParams[0];
pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422I_YUYV;
pCaptureOutPrm->scEnable = FALSE;
pCaptureOutPrm->scOutWidth = 0;
pCaptureOutPrm->scOutHeight = 0;
pCaptureOutPrm->outQueId = 0;
}
then when i do the loobback test,if i set the fps to be 60fps ,then the video will be a little jitter,but if 30fps,then it will be not jitter ,so why?
tks
