Hi,

Can you share the image of your usecase?
This error comes from the display link.If the system buffer format is not video frame.
Can you check which link is giving the output to display link as non video frame system buffer.

Hi Kim,

Could you please check if HapDist and Cencus Algorithms are outputting Video frame buffers? I am not sure about it.
Also could you please check if this assertion is coming from Display link or if not, which link is throwing this assertion?

Hi Brijesh,

How Can I check the output buffer type of the HapDist algorithm?
My usecase flow is HapDist -> Merge -> Display.

I checked this assertion is coming from Display Link(./vision_sdk/links_fw/src/rtos/links_ipu/display/displayLink_drv.c).

Hi Anuj,

I cannot share the image file cause the security policy of the company.
But I wrote the usecase as above.

If you need the SetAppPrms, I can inform you about this.
I use the three Display Links which are Alg_DmaSwMs -> Display_Org, Alg_DisparityHamDist (EVE1) -> Merge_StereoOut -> Display_Disparity and GrpxSrc -> Display_Grpx.

Hi Anuj,

As the log,
After "[HOST] [IPU2 ] 54.922070 s: pBuffer->bufType:2" is shown, the error message is shown.
When the bufType:1(Video Frame) is coming, the display is well.

[HOST] [IPU2 ] 54.922070 s: pBuffer->bufType:2 <----Meta data buffer (I don't know where this buffer come from)

I use the Isp channels buffer are 4.
And, the Census and Disparity algoritms use the 6 output buffers.

Thanks

Hi,

Is the output buffers of the Disparity algorithm meta data buffer?

Hi Anuj,

I logged to debug like below.

The ID 150994983 is Merge_StereoOut link and this buffer type is meta data buffer.
(The ID 150994993 is Alg_DmaSwMsLinkID)
The display link from Alg_DmaSwMsLink runs the display.
But, the display link from Merge_StereoOutLink has the meta data buffer.

I think that the sicne merge link from (Disparity algorithm+Dup_Census link) has the meta data buffer, the error is shown.

How can I do?

Thanks
Best regards,

Hi all,

I found that the Disparity algorithm use the meta data buffers. (disparityHamDistLink_algPlugin.c)
(pOutChInfo->flags = System_Link_Ch_Info_Set_Flag_Buf_Type(pOutChInfo->flags,SYSTEM_BUFFER_TYPE_METADATA);)

I'd like to check this algorithm run well or not.
Is it impossible?

Should I connect the StereoPostProceses algorithm?

Thanks
Best regards,
Heechang

Hi Kim,

I would suggest you to go through one of existing usecase where stereo is used. This will give idea as how difference algorithms can be used, what is their data types and how they can be connected and displayed. one of the examples is, network_stereo_display usease..
