Compiler/PROCESSOR-SDK-DRA8X: ISP

Hello,

If you have a camera with ISP, you can simply exclude the VISS node from the application. All of the modifications would occur only in the app_single_cam_main.c.

The output from the capture node in the existing app_single_cam_main.c is an object array containing raw images.  Since your camera has an ISP, the output object array in your new application would contain vx_image's which have a format of whichever data type that your camera node produces.  Instead of this object array going to the VISS node directly as the next node in the graph, you can either give the output to another processing node or directly to the display node.

Hi Lucas

I try modify the app_single_cam_main.c without VISS node, but the code can't work, can you help me modify the code or give me app_single_cam_main.c without VISS node, thanks.

[I have a new camera in TDA4,it has ISP（GW5200） in camera Module，I have config my register with TI960,but the  app_single_cam_main.c can't work, it have a node with VISS, how can I delete the VISS node in OPENVX software framework. by the way, The pattern mode with my camera have worked well.]

Hello,

Could you please describe the changes that you've made so far and what errors you are seeing?  And can you describe the nodes that you need still in your graph?  Is it just capture and display?

The output from the capture node in the single camera application has an output called cap_frames.  Presently, this is being given as an input to VISS.  However, you can simply give this as an input to display if you are wanting it to be just a capture -> display graph.

Lucas
