Hi,
We are porting OVX3C on TDA4VM.
OVX3C output data type is RAW12, resolution is 1920x1080.
We used SDK version is 7.0.0
If we remove ISS_SENSOR_FEATURE_DCC_SUPPORTED from sensor feature, we can get normal preview.
If we add ISS_SENSOR_FEATURE_DCC_SUPPORTED to sensor feature, we can't get imaging preview.
We did many debug and found:
1. we tried imx390 and ar0233, the result is same.
2. we found enable dcc, VISS will be suspend by under code
file: Vx_vpac_viss_target.c
static vx_status VX_CALLBACK tivxVpacVissProcess(
tivx_target_kernel_instance kernel,
tivx_obj_desc_t *obj_desc[],
uint16_t num_params, void *priv_arg)
{
...
/* Wait for Frame Completion */
tivxEventWait(vissObj->waitForProcessCmpl,
TIVX_EVENT_TIMEOUT_WAIT_FOREVER);
...
}
3. we found if we disable h3a output and disable h3a set, we can get imaging preview.
Could you help analyze the issue and give us some advice?
Thanks
