Please provide complete information as applicable to your setup.

**• Hardware Platform (Jetson / GPU) Jetson
**• DeepStream Version 6.2
**• JetPack Version (valid for Jetson only) 5.0.2
**• TensorRT Version 8.4.1.5
**• CUDA 11.4.239
**• cuDNN 8.4.1.50
**• Issue Type( questions, new requirements, bugs) questions
**•Requirement details:I have a pipeline deepstream test3

questions:It can run normally when I set export NVDS-TEST3-PERF_MODE=0; The following issues occur when exporting NVDS-TEST3-PERF_MODE=1.

eg.
/data/deepstream-6.2/sources/apps/sample_apps/deepstream-test3$export NVDS_TSET3_PERF_MODE=1
/data/deepstream-6.2/sources/apps/sample_apps/deepstream-test3$ ./deepstream-test3-app ./dstest3_config.yml
Now playing : file:///home/nvidia/work/data/gpu_decode/output.mp4

One element in source bin could not be created.
Failed to create source bin. Exiting.

There may be a problem with your installation environment, so that the nvurisrcbin plugins cannot be created. Could you update the DeepStream to the latest version 7.1?

Thank you for your reply. Can you explain why ‘Opening in BLOCKING MODE’ still appears in the log when I set NVDS-TEST3-PERF_MODE to 1.

These logs has nothing to do with the PERF_MODE. This is related to the decoder. You can refer to this topic 257153.
