What is the correct way to assign display width and height according to the input image? Sometimes we get the below error.

display_params.outWidth ;
display_params.outHeight;
display_params.posX ;
display_params.posY ;

VX_ZONE_ERROR:[ownContextSendCmd:784] Command ack message returned failure cmd_status: -1
VX_ZONE_ERROR:[ownContextSendCmd:818] tivxEventWait() failed.

    Hi,

    Could you clarify my below queries to get more clarity on the issue..

    1. Which SDK version are you seeing this?

    2. Is the display node, the only node in the graph? Where is it getting input from?

    3. Could you please share, how is the display node configured (i.e. pipe, outwidth, outheight etc)?

    4. Could you run "source vision_apps_init.sh" before you run your application? (This shall enable the remote side logs too.)
        Please share the logs of source vision_apps_init.sh and your application logs along with the remote core logs.

    Regards,
    Nikhil

    Hi team,

    What is the correct way to assign display width and height according to the input image for tivx_display_params_t ( tivxDisplayNode ) after image from VPAC VISS node.   

    tivxDisplayNode (vx_graph graph, vx_user_data_object configuration, vx_image image)

    display_params.outWidth ;
    display_params.outHeight;
    display_params.posX ;
    display_params.posY ;

     Sometimes we get the below error.

    VX_ZONE_ERROR:[ownContextSendCmd:784] Command ack message returned failure cmd_status: -1
    VX_ZONE_ERROR:[ownContextSendCmd:818] tivxEventWait() failed.
    VX_ZONE_ERROR:[ownNodeKernelInit:538] Target kernel, TIVX_CMD_NODE_CREATE failed for node node_119
    VX_ZONE_ERROR:[ownNodeKernelInit:539] Please be sure the target callbacks have been registered for this core
    VX_ZONE_ERROR:[ownNodeKernelInit:540] If the target callbacks have been registered, please ensure no errors are occurring within the create callback of this kernel
    VX_ZONE_ERROR:[ownGraphNodeKernelInit:583] kernel init for node 4, kernel com.ti.hwa.display ... failed !!!
    VX_ZONE_ERROR:[vxVerifyGraph:2044] Node kernel init failed
    VX_ZONE_ERROR:[vxVerifyGraph:2098] Graph verify failed

    Note: there is no error source visions_app_init.sh file 

    On the TDA4x board, we have used the following packages listed below.

    QNX SDP7.1 BSP for Texas instrument Jacinto 7 J721E (DRA829/TDA4xM )
    QNX Software Development platform 7.1
    ti-processor-sdk-qnx_j721e_07_03_00.tar.gz
    ti-processor-sdk-rtos-j721e-evm-07_03_00_07.tar.gz
