New nvstreammux "dropped" signal

• Hardware Platform (Jetson / GPU): GTX1650
• DeepStream Version: 6.1
• TensorRT Version: 8.2.5
• NVIDIA GPU Driver Version (valid for GPU only): 510.85.02


I started to use the new nvstreammux, and using gst-inspect I get this:

Element Signals:
  "dropped" :  void user_function (GstElement* object,
                                   gpointer arg0,
                                   gpointer user_data);

I find nothing in the documentation about this signal.
How could I use it, can it tell me the number of frames dropped by streammux per source?
If not, is there a way to know how many frames are dropped by streammux per source?


Currently this signal is not in use. Please ignore it.

Thanks @Fiona.Chen.
Do you have any advice of how I should retrieve the number of frames dropped by new nvstreammux?
Is there a recommended way?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one.

Maybe you can check the warning log. There will be “dropping late buffer pad id = x window_start =xxxxx src_buffer pts=xxxxx” print in the log.
