hi @Amycao,
thank you for your reply. After applying your suggestion and with your code, It will work with the callback function ur modify in deepstream_app.c
static GstPadProbeReturn
gie_primary_processing_done_buf_prob (GstPad * pad, GstPadProbeInfo * info,
gpointer u_data)
{
GstBuffer *buf = (GstBuffer *) info->data;
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 vehicle_count = 0;
guint person_count = 0;
NvDsMetaList *l_frame = NULL;
NvDsMetaList *l_obj = NULL;
AppCtx *appCtx = (AppCtx *) u_data;
NvDsObjEncCtxHandle ctx = nvds_obj_enc_create_context ();
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;
}
for (l_frame = batch_meta->frame_meta_list; l_frame != NULL;
l_frame = l_frame->next) {
NvDsFrameMeta *frame_meta = (NvDsFrameMeta *) (l_frame->data);
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 == PGIE_CLASS_ID_VEHICLE) {
vehicle_count++;
num_rects++;
}
if (obj_meta->class_id == PGIE_CLASS_ID_PERSON) {
person_count++;
num_rects++;
}
/* 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 == PGIE_CLASS_ID_PERSON
|| obj_meta->class_id == PGIE_CLASS_ID_VEHICLE)
&& num_rects == 1) {
NvDsObjEncUsrArgs userData = { 0 };
/* To be set by user */
userData.saveImg = save_img;
userData.attachUsrMeta = attach_user_meta;
/* Set if Image scaling Required */
userData.scaleImg = FALSE;
userData.scaledWidth = 0;
userData.scaledHeight = 0;
/* Preset */
userData.objNum = num_rects;
/*Main Function Call */
nvds_obj_enc_process (ctx, &userData, ip_surf, obj_meta, frame_meta);
}
}
}
nvds_obj_enc_finish (ctx);
write_kitti_output (appCtx, batch_meta);
return GST_PAD_PROBE_OK;
}
but it will fail when called handler again in bbox_generated_probe_after_analytics in deepstream_test5_app_main.c file. So I guess that. Because in your first call. The memory still in GPU 1 so It’s is extract and saving to disk but when recalled buffer again in the deepstream_test5_app_main the callback now is using GPU 0 so it cannot extract the memory. Does my thinking is right? Also I checked that, if I set gpu_id = 1 in config file. The application still using GPU 0 in somewhere. So I think this may cause problem
I’m really tired of this problem so please help me to fix it or explaining to me what I’m dealing to.
Thank you for your support
