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,
• DeepStream Issue
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

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) {

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 .
I try to fix several code from ajayskabadi2012 code and I have an error too.
Here is my code
static GstPadProbeReturn
gie_img_prob_new (GstPad * pad, GstPadProbeInfo * info, gpointer u_data)
{
GstBuffer *buf = (GstBuffer *) info->data;
GstMapInfo inmap = GST_MAP_INFO_INIT;
NvDsObjEncCtxHandle ctx = (NvDsObjEncCtxHandle) u_data;
NvBufSurface *ip_surf = (NvBufSurface *) inmap.data;
gst_buffer_unmap (buf, &inmap);
NvDsObjectMeta *obj_meta = NULL;
NvDsMetaList *l_frame = NULL;
NvDsMetaList *l_obj = NULL;
NvDsBatchMeta *batch_meta = gst_buffer_get_nvds_batch_meta (buf);
if (!gst_buffer_map (buf, &inmap, GST_MAP_READ)) {
GST_ERROR ("input buffer mapinfo failed");
return GST_PAD_PROBE_OK;
}
for (l_frame = batch_meta->frame_meta_list; l_frame != NULL;
l_frame = l_frame->next) {
NvDsFrameMeta *frame_meta = (NvDsFrameMeta *) (l_frame->data);
for (l_obj = frame_meta->obj_meta_list; l_obj != NULL; l_obj = l_obj->next) {
obj_meta = (NvDsObjectMeta *) (l_obj->data);
/* Conditions that user needs to set to encode the detected objects of
* interest. Here, by default all the detected objects are encoded.
* For demonstration, we will encode the first object in the frame */
if (obj_meta->class_id == 0 || obj_meta->class_id == 2 || obj_meta->class_id == 3 || obj_meta->class_id == 5 || obj_meta->class_id == 7) {
printf("%d\n", obj_meta->class_id);
NvDsObjEncUsrArgs userData = { 0 };
/* To be set by user */
userData.saveImg = FALSE;
userData.attachUsrMeta = TRUE;
/* Preset */
userData.objNum = 1;
/*Main Function Call */
**nvds_obj_enc_process (ctx, &userData, ip_surf, obj_meta, frame_meta);**
}
}
}
nvds_obj_enc_finish (ctx);
return GST_PAD_PROBE_OK;
}
and here is code inside create_common_elements function.
NvDsObjEncCtxHandle obj_ctx_handle = nvds_obj_enc_create_context();
if (!obj_ctx_handle) {
g_print ("Unable to create context\n");
return -1;
}
NVGSTDS_ELEM_ADD_PROBE (pipeline->common_elements.primary_bbox_buffer_probe_id,
pipeline->common_elements.primary_gie_bin.bin, "src",
gie_img_prob_new, GST_PAD_PROBE_TYPE_BUFFER,
obj_ctx_handle);
Other code works very well but when it refer to ‘ctx’, it cause segmentation fault.
Hi 1017oscar,
Please help to open a new topic for your issue.
Thanks
