DM388: capture create error on dm388

Hi Kailash,

I hope you are using IPNCRDK V3.8.1.

What is your capture device?

As i can see its failing while creating VIP handle so i doubt there is some issue in driver code.

I hope you have done the necessary changes for adding your capture device in HDVPSS Code.

In your create param you have not initialize a few param like videoDecoderId,inDataFormat etc.

Can you please initialize all the params and try again.

For captureLink Params reference you can look into the below file.

Hi Anuj,

Yes I am using IPNCRDK V3.8.1.

I am trying to get video input from Pentium 4 CPU with ubuntu installed on it, Through a VGA connector , output end is connected through CPU(the same output which goes to PC monitor) and input is connected to the VGA in of DM388EVM.

Here are my parameters. I believe these parameters are enough to start the capture link.

gVcapModuleContext.captureId = SYSTEM_LINK_ID_CAPTURE;
gVdisModuleContext.displayId[VDIS_DEV_HDMI] = SYSTEM_LINK_ID_DISPLAY_0;

/*Capture Link params*/
CaptureLink_CreateParams_Init(&capturePrm);
capturePrm.numVipInst = 1;
capturePrm.outQueParams[0].nextLink = gVdisModuleContext.displayId[VDIS_DEV_HDMI];
capturePrm.tilerEnable = FALSE;
capturePrm.vipInst[0].vipInstId = SYSTEM_CAPTURE_INST_VIP0_PORTA; //PORTA:24bit data, PORTB:8bit data

pCaptureInstPrm = &capturePrm.vipInst[0];
//pCaptureInstPrm->standard = SYSTEM_STD_1080I_60;
pCaptureInstPrm->standard = SYSTEM_STD_1080P_60;//SYSTEM_STD_VGA_60;
pCaptureInstPrm->numOutput = 1;
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;//SYSTEM_DF_YUV422I_YUYV;
pCaptureInstPrm->videoDecoderId = SYSTEM_DEVICE_VID_DEC_TVP7002_DRV;//SYSTEM_DEVICE_VID_DEC_TVP5158_DRV

pCaptureOutPrm = &pCaptureInstPrm->outParams[0];
pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422SP_UV;
pCaptureOutPrm->scEnable = FALSE;
pCaptureOutPrm->scOutWidth = 1920;
pCaptureOutPrm->scOutHeight = 1080;
pCaptureOutPrm->outQueId = 0;

thanks

Hi Anuj,

Thanks for replying i am able to create capture link with the following params but i am not able to start the capture link now
/*Capture Link params*/
CaptureLink_CreateParams_Init(&capturePrm);
capturePrm.numVipInst = 1;
capturePrm.outQueParams[0].nextLink = gVdisModuleContext.displayId[VDIS_DEV_HDMI];
capturePrm.tilerEnable = FALSE;
capturePrm.enableSdCrop = FALSE;

#if 1
for(vipInstId=0; vipInstId<capturePrm.numVipInst; vipInstId++)
{
pCaptureInstPrm = &capturePrm.vipInst[vipInstId];
pCaptureInstPrm->vipInstId = (SYSTEM_CAPTURE_INST_VIP0_PORTA+vipInstId)%SYSTEM_CAPTURE_INST_MAX;
pCaptureInstPrm->videoDecoderId = SYSTEM_DEVICE_VID_DEC_TVP7002_DRV;//SYSTEM_DEVICE_VID_DEC_TVP5158_DRV;
pCaptureInstPrm->inDataFormat = SYSTEM_DF_YUV422P;
pCaptureInstPrm->standard = SYSTEM_STD_AUTO_DETECT;//SYSTEM_STD_MUX_4CH_D1;
pCaptureInstPrm->numOutput = 1;

pCaptureOutPrm = &pCaptureInstPrm->outParams[vipInstId];
pCaptureOutPrm->dataFormat = FVID2_DF_YUV422I_YUYV;//SYSTEM_DF_YUV422P;//SYSTEM_DF_YUV422I_YUYV;
pCaptureOutPrm->scEnable = FALSE;
pCaptureOutPrm->scOutWidth = 640;
pCaptureOutPrm->scOutHeight = 480;
pCaptureOutPrm->outQueId = 0;
}

for(vipInstId = 0; vipInstId< capturePrm.numVipInst; vipInstId++)
{
vidDecVideoModeArgs[vipInstId].videoIfMode = DEVICE_CAPT_VIDEO_IF_MODE_16BIT;
vidDecVideoModeArgs[vipInstId].videoDataFormat = SYSTEM_DF_YUV422P;
vidDecVideoModeArgs[vipInstId].standard = SYSTEM_STD_AUTO_DETECT;//SYSTEM_STD_MUX_4CH_D1;
vidDecVideoModeArgs[vipInstId].videoCaptureMode =
DEVICE_CAPT_VIDEO_CAPTURE_MODE_MULTI_CH_PIXEL_MUX_EMBEDDED_SYNC;
vidDecVideoModeArgs[vipInstId].videoSystem =
DEVICE_VIDEO_DECODER_VIDEO_SYSTEM_AUTO_DETECT;
vidDecVideoModeArgs[vipInstId].videoCropEnable = FALSE;
vidDecVideoModeArgs[vipInstId].videoAutoDetectTimeout = -1;
}

OSA_printf("MultiCh_createVCaptureVDisplay1\n");
Vcap_configVideoDecoder(vidDecVideoModeArgs, 1);
#endif

My code is not able to do VCAP_START.
And seems link there is no support for TVP7002. Can you please take a look at the following post as well.

thanks
Kailash

small correction
pCaptureOutPrm->dataFormat = SYSTEM_DF_YUV422P; not pCaptureOutPrm->dataFormat =FVID2_DF_YUV422I_YUYV;

thanks

Hi Kailash,
If possible then can you share your usecase file.
If you have any issue in sharing it publicly then please send it to my email-id.(If you need please ask)
Share your boot logs also.

Hi Anuj,

Can you share your email id, I will share my code .

My capture create and start is successfull but i am not getting any data from the input source , HDMI display shows up green/blue/black even if i am not connecting any input.

My set up is VGA cable is connected to VGA connector which is connected to tvp7002 on DM388EVM , source of input is Pentium 4 cpu.


Thanks
Kailash
