Deepstream-test3 (Python)

Hi Team,
I run deepstream-test3 sample app in python. With the code as such, I’m able to see the frame number getting updated throughout. However if I attach the probe function to the src_pad of tiler, I can only see the object count and person count getting updated and the frame count stucks at 0. This happens even if the probe is attached to nvosd sink and src pads. Attaching the updated code for reference. Kindly let me know what could be the issue.

My setup doesn’t have binding for pyds.configure_source_for_ntp_sync(hash(uri_decode_bin)), thus remove this line and “Frame Number” can increase it correctly, does it related with configure_source_for_ntp_sync in your setup?

I’ll remove the binding call, check and get back.

Hi @yingliu ,

Even if I remove the call pyds.configure_source_for_ntp_sync(hash(uri_decode_bin)), frame number is not getting updated. Can you make sure the probe function is attached at the src pad of nvosd and not at pgie.

The Gst-nvmultistreamtiler plugin composites a 2D tile from batched buffers. Currently, the frame_num parameter has not been set in this plugin.
You can use a global variable to count it by yourself now. We’ll consider to set that parameter in this plugin. Thanks

Okay, thanks.
