Hi all

We are trying to generate priv.c & priv.h for the dualcamera-usecase with write-back . We are getting error as below.

Config file:

UseCase: weston_dualcamera_dsswb

Capture_0 -> Display_Video0
Capture_1 -> Display_Video1
DefLink_dispDist (A15) -> Display_Gfx
DefLink_dispDist_1 (A15) -> Display_vid1
Capture_dsswb -> Alg_SwCrc

Error

D:\workspace\weston_dualcamera_dsswb>vsdk_win32.exe -file weston_dualcamera_dsswb.txt

Warning: Custom defined Algorithm plugin Link [SwCrc] found !
Warning: Custom defined Link [DefLink_dispDist] found.

Warning: Custom defined Link [DefLink_dispDist_1] found.
You will need to manually edit the generated .c file

Error: Link [Capture] cannot have more than two instance !!!

We have a single camera usecase as below & It is working.
UseCase: weston_m4camera_dsswb

Capture -> Display_Video

DefLink_dispDist (A15) -> Display_Gfx

DefLink_dispDist_2 (A15) -> Display_vid2

Capture_dsswb -> Alg_SwCrc

Please support for the dualcamera usecase.

Only single capture link instance is supported In the UC gen tool, you need to modify the tool to support multiple capture links
Source code of UC gen tool is under - S:\shiju\ADAS\vision_sdk\apps\tools\vision_sdk_usecase_gen
Modify and rebuild the tool

Another option is to use Single capture link with 2 ch capture, in this case you can use the Tool as is

Hello Shiju,

I have made below changes and able to generate source code. For the new capture instance can I just create new link ID in system_linkId.h for the 3rd Capture instance and use it ? or Is there any other options available. Please advice .

Thank you for your time,
Raghu

Hello
yes, your changes are correct.
BTW, The tool support 2 instance if capture link. Why do you need the third instance?

Hi shiju,

We have dualcamera usecase as below. We like to use the writeback pipeline for freeze detection .

UseCase: weston_dualcamera_dsswb

Capture_0 -> Display_Video0
Capture_1 -> Display_Video1
Capture_dsswb -> Alg_SwCrc

For single camera, we have used "vip_single_cam_view_dsswb " as reference.

Gokul

Hi Shiju,

Is it enough to add new link ID in system_linkId.h for the 3rd Capture instance and use it ? Is it good to add at the end or after capture_1 ?

Regards,
Gokul

yes, modify system_linkId.h by adding a new capture link ID and then modify the UC Gen tool to support 3 instances
