Please provide complete information as applicable to your setup.

**• Hardware Platform (Jetson / GPU)**Jetson
• DeepStream Version5.1
**• JetPack Version (valid for Jetson only)**4.5.1
• TensorRT Version7.1.3
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)
My pipeline logic diagram is like this.

streammux-> pgie-> tracker->sgie1->sgie2->sgie3->tee
queue1->nvvidconv_report->caps_filter-> fakesink-> NULL
queue2->tiler-> nvvideoconvert->nvosd_show->nvtransform,sink, NULL

It can run ok,but I just add a probe in caps_filter moudle to save img by opencv,I get the follow critical in two video input.
gst_mini_object_unlock: assertion ‘(state & access_mode) == access_mode’ failed

Hi,
The pipeline looks similar to

/opt/nvidia/deepstream/deepstream-5.1/sources/apps/sample_apps/deepstream-test2

Please apply your code of adding a probe to this sample and try again. The runtime_source_add_delete app is a more complex case. Suggest you try simpler deepstream-test2 app for comparison.

Thans,it can work on single input.Now i use dsexample replace my own probe in there,and it can work too many input.
