Hi,
When I run the deepstream-nvdsanalytics-test sample app I notice that on detected vehicles a direction gets added to the bounding box overlay. For example it says “Vehicle 123131234 DIR: North” or if the vehicle stops it says “Vehicle 123131234 STOPPED”. If I try to recreate that same setup with the deepstream-app the “DIR: North/South” or STOPPED text does not get added to the overlay. How do I enable that?
Hi,
I try to repro your issue by below command, but can not, you should make some changes based on deepstream-app, right? can you share for a local repro?
sudo gst-launch-1.0 filesrc location= /opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_1080p_h264.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! m.sink_0 nvstreammux name=m width=1920 height=1080 batch-size=1 ! nvinfer config-file-path= nvdsanalytics_pgie_config.txt ! nvtracker ll-lib-file = /opt/nvidia/deepstream/deepstream/lib/libnvds_nvdcf.so ll-config-file= /opt/nvidia/deepstream/deepstream-5.0/samples/configs/tracker_config.yml tracker-width=640 tracker-height=384 ! nvdsanalytics config-file= config_nvdsanalytics.txt ! nvmultistreamtiler ! nvvideoconvert ! nvdsosd ! nvegltransform ! nveglglessink
I was expecting the deepstream-nvdsanalytics-test app, the gst-launch pipeline and the deepstream-app to give the same visual results with the same configuration but deepstream-app seems to give a different result. I would love to know why it’s doing that and how to make it output the same overlay info as the other two methods.
For simplicity’s purpose, the deepstream-app displays lesser overlay info about the detected objects i.e. the application-specific metadata is removed from obj->text_params.display_text parameter which contains the text to be displayed.
So if you want to access the info such as the direction you have to make changes accordingly in obj->text_params.display_text parameter present in process_meta() of deepstream_app.c file
or you can disable process_meta () if you want to display as expected in the nvdsanalytics test app or pipeline.
