Dear Margarita,

OK, I involve Oddy to here to show the problems and our progress on the project,he is my colleague.

thanks again.

Jiger

Hi,

We have solved  last problem,but we have a new problem in video color .It looks like Y/C components are swapped.The image attached as below.Pls give me some good advice .

thanks.

Jiger

Hi Jiger,

You are doing YUV 16 bits capture from ISS right. I assume you have provided the snapshot of YUV 422 output from resizer - is this correct?

How do you intend to use the YUV-422 in your dataflows? If you need it for display via HDVPSS then the HDVPSS driver supports both UV & YV formats to account for luma/chroma swap. 

Please provide some more details on the intend use. For example, if the intention is only for encoding and streaming out, then the RSZ output from ISS should be YUV 420 and not YUV 422.

Hi  Rajat Sagar:

This is oddy,I am doing the DM8148(8127)IPNC camera case.the dataflows like this:BT1120--->camera interface --->(ISS)RSZ------->output.

1.in function:MultiCh_createTriStreamFullFtr(),I did the modification:

#ifdef IMGS_MCR_MUX  

    pCameraInstPrm->inDataFormat =SYSTEM_DF_YUV422SP_UV

#else  

    pCameraInstPrm->inDataFormat = SYSTEM_DF_YUV420SP_VU;// original

 #endif

in fact,setting  inDataFormat to SYSTEM_DF_YUV422SP_UV has the same result with SYSTEM_DF_YUV420SP_VU.

2. for ISS part :src\issdrv_captureApi.c

 #ifdef IMGS_MCR_MUX    

rsz_reg->SRC_VSZ  = 1079;    

 rsz_reg->SRC_HSZ  = 1919;

 rszA_reg->RZA_V_DIF  = 256;    

 rszA_reg->RZA_H_DIF  = 256;  

 rszA_reg->RZA_DWN_EN  = 0;    

 rszA_reg->RZA_DWN_AV  = 0;

 rszB_reg->RZB_V_DIF = 576;  

 rszB_reg->RZB_H_DIF = 682;  

 isif_reg->MODESET = 0x100C;   //for YUV 16bit    

isif_reg->HSIZE = 120;    

ipipe_reg->SRC_FMT = 0x3;

isif_reg->CCDCFG = (0x0 |(7<<11) |(7<<6) | (1<<4) );

 isif_reg->CCOLP   = 58596;  

 isif_reg->CGAMMAWD  = 16; 

 isif_reg->SPH       = 0;

 ipipeif_reg->CFG2 = 0x8F ;

  gIss_captCommonObj.pModuleInstance->nLscTableIsValid       = MSP_TRUE;

  ipipe_reg->WB2_WGN_R = 600; //White Balance Register White balance gain for R in U4.9 format 0 to +15.998 default 0x0200    

  ipipe_reg->WB2_WGN_B = 750; // same to up    

   ipipe_reg->RGB1_MUL_RR = 256;    

  ipipe_reg->RGB1_MUL_GR = 0;   

  ipipe_reg->RGB1_MUL_BR = 0;   

  ipipe_reg->RGB1_MUL_RG = 0;    

  ipipe_reg->RGB1_MUL_GG = 256;   

   ipipe_reg->RGB1_MUL_BG = 0;   

  ipipe_reg->RGB1_MUL_RB = 0;   

  ipipe_reg->RGB1_MUL_GB = 0;    

  ipipe_reg->RGB1_MUL_BB = 256;  

  isif_reg->HDW = 1919;//1921;

   isif_reg->VDW = 1079;//1081; 

 #endif

Dear Rajat,

We are using Camera Interface(I/F)  receiving the video data( 16bit, BT.1120.Embedded sync mode,YUV422 format) on DM8148.The hardware is base on APPRO's DM8127 IPNC and the software is IPNC RDK3.2. We connect the sensor with DM8148 board. this sensor output BT.1120/1080P(YUV422 format).We configure some ISS registers,and DM8148 board can accept the video data( 16bit,YUV422 format),but the color of the image is not right. We can confirm the senor works well.

DM8148 board with the sensor  is the same as the HD IP camera.

We think both U and V are reversal. how to swap U/V in ISS driver?

Regards

Jiger

Jiger,

You cannot swap the U/V in ISS output because what you are seeing is the fixed format in which ISS RSZ outputs YUV-422.

But this is typically not a problem because when you use YUV-422 output in any other subsystem in the SOC for example HDVPSS, the ISS output format is also supported. Also, you can switch to YUV420 output format from the RSZ incase you want to use this output diretly for encoding.

If you can tell me what do you want to do with the YUV 422 output frame I can suggest the datapath.

Regards

Rajat

Also, I wanted to add that ISS RSZ supports in-line conversion from YUV422 to YUV420.

Regards

Rajat

Jiger

your want to change from 

 UY VY UV VY

to

VY UY VY UY

right?

Why not just increase RSZ_SRC_HPS+1?

Best regards,

Christian.

Dear Rajat,

We are developing a HD IP-Video server,with HD-SDI input ,network output. there is a FPGA as HD-SDI input receiver,the FPGA output BT.1120 16bit data.Please give me some advices on this issue,how to conversion from YUV422 to YUV420?You great help is appreciated.

Best regards

Jiger

Dear Christian and Rajat,

Thank you very much ,our product is HD-SDI Viedo Server.The schematic of  HD-SDI Video Server as below:

Best Regards

Jiger

Dear Christian:

    the iss datasheet says:

and you said:Why not just increase RSZ_SRC_HPS+1?

in my case. which value is more appropriate for  RSZ_SRC_HPS .

oddy

thks

Jiger,

Based on my understanding of your usecase, you will need only YUV420 data output for encoder and also sufficient even if you want to do preview via HDMI, SD.

To get YUV420 output you just need to set the output format as YUV420. The driver supports it. 

Internally what will happens is that VP will capture BT.1120 YUV 16 bits and will send to the ISIF->RSZ (DMA). The RSZ is supposed to DMA out the buffers and also has the capability to do upscale, downscale and chroma downsampling. In current case, setting output format as YUV420 will enable the chroma downsampler in RSZ which will output the YUV420 into the output buffers. The YUV420 data can be directly sent to encoder, display etc.

Regards,

Rajat

Dear Rajat,

You said DM8148 driver supports YUV420 not YUV422 by camera interface accepting video data,but in  DM8148 manual, ISS supports YUV422(8bit or 16bit) data( 281 page of manual), please check it.

Best Regards

Jiger

Dear Christian,

Yes ,we want to change from UY VY UV VY to VY UY VY UY,how to do it ,please give me details on configration.Now we want to try all kinds of method to solve the problems

Best Regards

Jiger

Hi Jigar,

I am not sure about the ISS but VIP can support BT1120 and we could store the output in either YUYV or UYVY format. i can provide mode details on this if you are interested.

Regards,

Brijesh Jadav

Dear Brijesh Jadav,

Our design is base on DM8127 IPNC .the dataflows :BT1120--->camera interface --->(ISS)RSZ------->output. We are using the Camera interface port of DM8148,not vin port.

We need to configre ISS not HDVPSS.

Best Regards

Jiger

Dear Rajat,

It is hard to change YUV422 data output to YUV420 data output in FPGA, can you add that ISS RSZ supports in-line conversion from YUV422 to YUV420 ?

thanks

Best Regards

Jiger

Jiger,

I understand. I was explaining that capture from VP can be YUV422 16bit, but output of the RSZ should be YUV 420.

The driver already supports output of YUV420. To enable YUV420 output please make sure that 'pCameraOutPrm->dataFormat = SYSTEM_DF_YUV420SP_VU' in the mcfw usecase file.

Regards

Rajat

Dear Rajat,

OK ,I see,and Oddy will follow it ,thank you very much.

Regards

Jiger

Dear Rajat,

We have not any progress on this issue,can you give us a configuration of sample with YUV422 input by I/F port of DM8148 for our reference?or you can give us some advices on this issue.thank you very much.

Regards

Jiger

Can you attach and send the multich_tristream_fullfeature.c file? Also, please confirm if you changed any code in ISS drivers pacakge, especially \packages\ti\psp\iss\drivers\capture\src\issdrv_captureApi.c file.

If the output is YUV422I and the same output goes to the encoder the colors will be inaccurate. The setting for converting from YUV422 to YUV420 is done by the RZA_420 register in ISS_RESIZER section of the ISS register manual. Also the inDataFormat value in the above code will not make any difference.

I think because of some other issue in the code the YUV420 setting is not working for you and this needs to be debugged.

Regards

Rajat

Dear Rajat:

thanks very much for your help.

I attached the source code about the modifaction.it can be work ok but the color in abnormal.i think there are some mistake to config the rigesters about IPIPE RSZ and ISIF wish a good news from you.

Dear Rajat,

Xue have solved the same problem after he had the same problems.The link as below.

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/221064.aspx?pi70909=1

He said he Modify the rsz_reg,rszA_reg,rszB_reg,isif_reg,isife_reg in Iss_captCreate function in issdrv_captureApi.c.  The SPRUH30 is talk about these registers.

But we have not progress yet untill today.please give us some advice on this issue.

thank

Jiger

oddy,

the idea is if RSZ read the next pixel , the UY VY read sequence will be inversted.

so what is the current RSZ_SRC_HPS value which you're using,

and what the image will be like if you increase the value by 1 and give it to RSZ_SRC_HPS?

Best regards,

Christian.

FYI:

I use RDK3.2, custom DM8148 board, video input is YUV422/Discrete sync 1080P from FPGA.

I didn't modify usecase files at all. Most of the changes are in issdrv_captureApi.c

@line 121:

- #if defined IMGS_OMNIVISION_OV10630

+ #if defined IMGS_OMNIVISION_OV10630 || defined OUR_YUV_SENSOR

in Iss_captCreate().

#if defined OUR_YUV_SENSOR
    ipipe_reg->SRC_FMT=3;
    ipipe_reg->SRC_HPS=0;
    ipipe_reg->SRC_VPS=0;
    ipipe_reg->SRC_COL  = 27;

    ipipeif_reg->CFG1 = 0;
    ipipeif_reg->CFG2 = 0x0E;
    isif_reg->MODESET = 0x100c;   //for YUV
    isif_reg->CCDCFG = 0;
    isif_reg->SYNCEN = 1;
    isif_reg->CLDCOFST = 0;

    rsz_reg->SRC_VSZ    = 1079;
    rsz_reg->SRC_HSZ    = 1919;
    rsz_reg->SRC_HPS = 0;
    rsz_reg->SRC_VPS = 0;
    rszA_reg->RZA_O_VSZ = 1075;
    rszA_reg->RZA_O_HSZ = 1919;
    rszA_reg->RZA_SDR_Y_OFT=0x780;
    rszA_reg->RZA_SDR_Y_PTR_S=0;
    rszA_reg->RZA_SDR_Y_PTR_E=0x438;

    rszA_reg->RZA_V_DIF         = 256;
    rszA_reg->RZA_H_DIF     = 256;
    rszA_reg->RZA_DWN_EN    = 0;
    rszA_reg->RZA_DWN_AV    = 0;
#endif

thanks very much.I will try it later.

oddy

oddy,

good to see this, but you disabled ISIF?

Best regards,

Christian.

Dear Christian：

if  the  isif_reg->SYNCEN = 1;there is no images to display.when this register set to 0, the image is OK. 

I want to konw what willl happen when i disable the ISIF?
