How to captrue 1080I/60fps ,which params should be setting?

Hi,

I work on DM8168 ,EZSDK 5.0.3.15! I have run the Capture_ Encode Example example with input 720p/60 video signal, and now i want to run the Capture_ Encode Example example with input 1080I/60 video signal.So i changed the code ,

In file iIclient_utils.c  i make the following changes .

In function void IL_ClientInit (IL_Client **pAppData, char *mode, int frameRate,int bitRate, int numFrames, int displayId)

I add the following mode:

  else  if (strcmp (mode, "720p") == 0) {
   pAppDataPtr->nHeight = 720;
   pAppDataPtr->nWidth =  1280;
  }

 else if (strcmp (mode, "1080i") == 0) {
   pAppDataPtr->nHeight = 1080;
   pAppDataPtr->nWidth =  1920;
  }

and  in the function OMX_ERRORTYPE IL_ClientSetCaptureParams (IL_Client *pAppData)

   all sHwPortParam.eScanType       = OMX_VIDEO_CaptureScanTypeProgressive;  replaced with

  sHwPortParam.eScanType             = OMX_VIDEO_CaptureScanTypeInterlaced;

and

sVidDecParam.videoStandard =  OMX_VIDEO_DECODER_STD_1080I_60;

In function OMX_ERRORTYPE IL_ClientSetDisplayParams (IL_Client *pAppData)

 driverId.eDispVencMode = OMX_DC_MODE_1080I_60;

then i run the program ,but the color is green ,is there any other place i have to change?
