TDA4VH-Q1: flickering issue in one cam from ldc node

Part Number: TDA4VH-Q1

i m using 2 camera one 5b cam and one 8b cam conversion of color convert node by using ldc .5b cam is working and for 8b cam flicker issue is there.

obj->colorConvertNode = tivxVpacLdcNode(
obj->graph,
obj->ldcConvertCfg, /* configuration */
NULL, /* warp_matrix — no geometric warp */
obj->ldcConvertRegion, /* region_prms */
NULL, /* mesh_prms — no mesh */
NULL, /* mesh_img — no mesh */
NULL, /* dcc_db — no DCC */
uyvy_in, /* in_img UYVY */
nv12_out, /* out0_img NV12 */
NULL); /* out1_img — single output */
printf("[LDC-8B] tivxVpacLdcNode: %s\n",
obj->colorConvertNode ? "OK" : "FAIL — NULL");
any debug steps can you suggest
  • Hi Basil,

    Most likely the flicker is not due to LDC node, but it could be due to how you have created the graph and how these two LDC nodes are connected. So could you please share this part of the graph for the review ?
