大家好：
我用DM8168 采集 1080 I 60 的视频源 然后---->dei------>enc--------->rtsp
vlc点播的图像是1920*540的分辨率
SII9135设置跟逐行采集是一样的
我cap设置：
pCaptureInstPrm = &capturePrm.vipInst[vipInstId];
if(vipInstId == 0)
pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP0_PORTA;
else
pCaptureInstPrm->vipInstId = SYSTEM_CAPTURE_INST_VIP1_PORTA;
pCaptureInstPrm->videoCaptureMode = SYSTEM_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC;
pCaptureInstPrm->videoIfMode = SYSTEM_CAPT_VIDEO_IF_MODE_16BIT;
pCaptureInstPrm->inScanFormat = SYSTEM_SF_INTERLACED;
pCaptureInstPrm->videoDecoderId = 0;
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;
pCaptureInstPrm->standard = SYSTEM_STD_1080I_60;
pCaptureInstPrm->numOutput = 1;
pCaptureOutPrm = &pCaptureInstPrm->outParams[0];
pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422I_YUYV;//SYSTEM_DF_YUV422I_YUYV;//SYSTEM_DF_YUV420SP_UV;
pCaptureOutPrm->scEnable = FALSE;
pCaptureOutPrm->scOutWidth = 0;
pCaptureOutPrm->scOutHeight = 0;
pCaptureOutPrm->outQueId = 0;

想问下 可能是什么原因引起的这种问题
