We are trying to run the image save in deepstream5 app example from weeks but unable to get output, can you please share how to run the deepstream-image-meta-test test app in deepstream5 app example.
Please kindly share your insights, will really appreciate.
Thank You,

Can you run deepstream-image-meta-test app well?
BTW, would you mind to share your env setup?
Yeah, deepstream-image-meta-test runs well.
But similar image saving wanted to integrate with deepstream-app5, where followed below steps,
Code:
In depstream-app/deepstream_app.c
//NEW FUNCTION ADDED
static GstPadProbeReturn

gpointer u_data)

AppCtx *appCtx = (AppCtx *) u_data;
NvDsBatchMeta *batch_meta = gst_buffer_get_nvds_batch_meta (buf);
if (!batch_meta) {
NVGSTDS_WARN_MSG_V ("Batch meta not found for buffer %p", buf);
return GST_PAD_PROBE_OK;
}
GstMapInfo inmap = GST_MAP_INFO_INIT;
if (!gst_buffer_map (buf, &inmap, GST_MAP_READ)) {
GST_ERROR ("input buffer mapinfo failed");
return GST_FLOW_ERROR;
}
NvBufSurface *ip_surf = (NvBufSurface *) inmap.data;
gst_buffer_unmap (buf, &inmap);
NvDsObjectMeta *obj_meta = NULL;

guint num_rects = 0;
for (l_obj = frame_meta->obj_meta_list; l_obj != NULL; l_obj = l_obj->next) {
obj_meta = (NvDsObjectMeta *) (l_obj->data);
if (obj_meta->class_id == 1) {
vehicle_count++;
num_rects++;
}
if (obj_meta->class_id == 0) {
person_count++;
num_rects++;
}
/* Conditions that user needs to set to encode the detected objects of

if ((obj_meta->class_id == 0
|| obj_meta->class_id == 1) && num_rects == 1) {
NvDsObjEncUsrArgs userData = { 0 };

Kindly help provide suggestions on implementing image saving in deepstream-app5.
Thank You,
There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one. Thanks
Could you share your setup info?
Also what’s the log when you run your customized ds-test5?
Per your code, seems you didn’t pass the “obj_ctx_handle” to the gie_img_prob_new .
