I have an error when trying to draw a bbox on multi-sink:
** Unable to draw shapes onto video frame by GPU

I have 2 sinks: file sink + chunk sink.
Pipeline:

  • .... ! tee ! ghost pad ! queue ! nvvideoconvert ! nvosd ! nvvideoconvert ! .... (file sink)
           ! ghost pad ! queue ! nvvideoconvert ! nvosd ! nvvideoconvert ! ... (chunk sink)

How can I change the pipeline to draw a bbox for multi-sink?
Thank you so much!

what do you mean about “Unable to draw shapes onto video”? how did you do that? could you share a simplified and detailed Gsteamer cmd to reproduce this issue? what is chunk sink? Thanks!

Hi Fanzh, thank you for your response.
Basically, I have a C++ project using the DeepStream SDK, and I have 2 sinks—2 different queues from the tee—and can draw bounding boxes undependently.
When I just set bbox=true for only one sink, it can run great. But when I try with bbox=true for both, it crashes with the error GPU unable to draw shapes.

  1. could you share a simplified Gsteamer gst-launch command-line to reproduce this issue? Thanks!
  2. About “bbox=true”, do you mean set display-bbox to true for nvdsosd plugin?

please set disable-passthrough to true for nvvideoconvert before nvsdosd in two tee branches.

Hi Fanzh,
Thank you for your suggestion.
I have updated to set ‘disable-passthrough’=1 for nvvideoconvert and it’s working.

Thanks for the update, Is this still an DeepStream issue to support? Thanks!

Yes, thank you so much!
