Forum Post: TI8148 VPSS : Captured Image not in proper size

Hi,

Currently I'm working on TI8148 with adv7180 encoder/decoder attached to VIN[0] port A.

I am using saLoopBackFbdev application to capture the video from the adv7180.

When I executed saLoopBackFbdev, I am able to capture the image but the image not in proper size.

I am using PAL (720 x 576), BT656 standard. 

PAL format to DSP is <SAV Cb Y Cr Y Cb Y Cr .... EAV>.

Here is my input to adv7180 chip.

Here is my configurations,

cctrl->ccparams->videoCaptureMode = VPS_CAPT_VIDEO_CAPTURE_MODE_SINGLE_CH_NON_MUX_EMBEDDED_SYNC;

cctrl->ccparams->videoIfMode = VPS_CAPT_VIDEO_IF_MODE_8BIT;

cctrl->ccparams->inDataFormat = FVID2_DF_YUV422P;

cctrl->ccparams->periodicCallbackEnable = 0;

cctrl->ccparams->numCh = 1;

cctrl->ccparams->numStream = 1;

cctrl->ccparams->vipParserInstConfig = NULL;

cctrl->ccparams->cscConfig = NULL;

cctrl->ccparams->vipParserPortConfig  = NULL;

cctrl->ccparams->inScanFormat = FVID2_SF_INTERLACED;

cctrl->decoder_width = 1920;

cctrl->decoder_width = 1080;

cctrl->scformat = FVID2_SF_INTERLACED;

cctrl->fmt.channelnum = 0;

cctrl->fmt.width = 1920;

cctrl->fmt.height = 1080;

cctrl->fmt.pitch[0] = 1920 * 2;

cctrl->fmt.pitch[1] = 1920 * 2;

cctrl->fmt.pitch[2] = 1920 * 2;

cctrl->fmt.fieldmerged[0] = 0;

cctrl->fmt.fieldmerged[1] = 0;

cctrl->fmt.fieldmerged[2] = 0;

cctrl->fmt.dataformat = FVID2_DF_YUV422P;

cctrl->fmt.scanformat = FVID2_SF_INTERLACED;

cctrl->fmt.bpp = 24;

Kindly tell me what could be the problem in my configuration?
