Hi,

May I know if this sensor is tested with the multi cam application and you are able to see the image correctly on the display?
if not, could you check the same?

May I know what is the format that is being output from the sensor?

Regards,

Nikhil

HI NiKhill 

      I tested multi-cam,it could save photo and  it is ok

      sensor output  format  is raw12

     can you  tell me  how to close the ldc enable of multi-cam_codec?

Hi,

LDC disable option was not provided here because the input to the codec should be NV12, hence LDC is also used to convert to NV12.

If you already have NV12 output from VISS node, then you would have to manually remove the LDC from the application and point the obj->enc_pool.arr to obj->vissObj.output_arr (if you are not using downscale)

Regards,

Nikhil

Hi NiKhill

    I just modified that  point the obj->enc_pool.arr to obj->vissObj.output_arr ,as the below picture,Is this how the modification was made？Did not solve the stripe problem。

thanks！

Hi NiKhill

  Changing the output resolution to 1920 * 1080  normal recording video

Hi NiKhill

    I am sorry to provided incorrect information.if  I just modified that  point the obj->enc_pool.arr to obj->vissObj.output_arr,runing app will report error as below.thanks!

Is this correct?

You would have to remove the ldc module completely from the graph as this is linked to the viss_node. i.e. remove ldc_init, create, delete APIs from the application.
I hope you are not using MSC node right?

Hi Daohong

This is not splash, but some problems caused by the wrong/initial DCC parameter. You may do the following change to disable LDC.

1 comment line 1204-1208(main.c)

2 modify line 1215 (main.c)

Or you can add the correct LDC parameters after LDC tuning.

Hi Adam

      To modify and close LDC as you mentioned, you need to enable obj ->downscale,but still repord some error,I am sending you the code currently using. Could you please help me take a look

 and Where is initial DCC parameter?0647.main.c

Hi Daohong

DCC parameter is under RSDK/imaging/sensor_drv/src/<sensor name>/dcc_xmls. You may try restore the modification I put above and disable LDC in LDC xml:

After changing the dcc xml, run generate_dcc.sh under the same directory. 

Then remake imaging to make the modification in effect.

Best regards,

Adam.

 Hi Adam

       Directly modify dcc_ xml ,Turn off LDC for XML,run generate_dcc.sh but the recording issue remains unchanged.

 Hi Adam 

     Can you take a look at the C file I sent and how to directly remove the LDC driver and run it without reporting any errors？

       thanks

Hi daohong

I have tested disable LDC on xml and it has been proven useless too. You may try another demo app_multi_cam. This demo can disable LDC by setting app_muti_cam.cfg.

I am looking at your code and trying to see how to disable LDC. Please wait for some time.

Best Regards,

Adam

You had mentioned that you were able to get the multi-cam demo working right? 
Could you please confirm if you were displaying the output here with LDC enabled or LDC disabled?

Regards,

Nikhil

Hi Nikhil

     I also comfirmed multi-cam demo ,There's no difference for LDC enabled or LDC disabled.save photo normal,thanks

Hi Daohong

After closely looking at your video, I think the LDC has been tuned in your sensor. Would you please add a folder 'app_cam_out' under 'vision_apps' and enable the following to enable saving images:

When running the demo, press 's' to save the images, which will appear in 'app_cam_out', to see where is the problem introduced.

further more, what is the property of the video you shared?

Hi Adam

        Running multi cam, the saved images are normal, but the recording is not normal. The attribute of recording is 4k.

Hi,

Sorry, did not understand this. Could you please elaborate what is saved images here (i.e. output of which node) and what is recording (output of which node) and how are you recording?

Regards,

Nikhil

What is the size of the saved images?

I think the problem is not resulted from LDC. If the image input to encoder is much less than 4k, the encoded 4k image should have such strange distortions. Please confirm that the output of LDC is 4K.

Hi Adam  

    I  run the nulti-cam_codec app ,press 'S' to save photo and recording video,save photo of output  node is ldc node,the  attribute of save photo also  is 4K,the photo and video  all have the same problem。so the input of encode have problem.thanks

Hi Adam

    How to set resolution of ldcObj output? I attempt to modify  "LDC_TABLE_WIDTH" value ,It doesn't seem right？

Hi Adam

    How to set resolution of ldcObj output? I attempt to modify  "LDC_TABLE_WIDTH" value to 4K of single-cam ,It doesn't seem right？An error occurred while running the single-app

Hi daohong

The resolution of LDC is not configurable directly. The resolution of the raw image is set by sensor driver. The raw image go through VISS without change in resolution. LDC will change the resolution based on the LDC LUT.  The resolution can be changed in MSC. However, MSC is only able to scale down the image but not scale up. Would you please share the image captured from VISS, LDC and the initial raw image?

Hi Adam

   I can't upload image to e2e,but when  I run ./run_app_multi_cam_codec.sh save image information ,the resolution is samed with setting of  poolObj->width and poolObj->height.

Record a 2M video ,the output of ldc is2M,Record a 8M video ,the output of ldc is8M

the resolution of ldc output is samed with setting of  poolObj->width and poolObj->height

Hi daohong

Is this CSI input raw and the viss_img_out normal? You may paste the screenshots of the images if the images are too big to upload or pack images to a zipped file and upload or send to me directly through email. 

Hi Adam

    CSI input raw and the viss_img_out  is normal,only 8M output of ldc and 8M record video is  abnormal 

  thanks!

Hi Adam   

   this is recoed 8M video ,saved photo of ldc and viss,the ldc output is abnormal

Hi Daohong

please check the LDC xml parameters as follows,

I think the LDC of your sensor is just tuned for a smaller size than 4K or the LUT is not correct. If so, just get your ISP tuning team to tune the LDC again. 

Hi Daohong

And how did you change the output of LDC in multi_cam_codec demo?

Hi Adam 

     I didn't changed successfully if I changed the parameter "LDC_TABLE_WIDTH" to 4k resolution ,it will report an error 

Hi Adam 

 just change  poolObj->height and poolObj->width
