Instance : 1** WARN: <parse_streammux:821>: Unknown key 'config-file-path' for group [streammux]

Hardware Platform (Jetson / GPU):
GPU (NVIDIA GeForce RTX 4090)

• DeepStream Version:
7.1

• JetPack Version (valid for Jetson only):
N/A

• TensorRT Version:
10.7.0.23

• NVIDIA GPU Driver Version (valid for GPU only):
565.57.01

• Issue Type:
I am using DeepStream 7.1 and facing an issue with setting up the streammux configuration. Here’s my setup:

In the [streammux] section of my config file, I have added the following line:

Steps I Have Taken:

1. Added config-file-path to the [streammux] section in the config file.
2. Set the environment variable USE_NEW_NVSTREAMMUX to yes.
3. Verified the file path exists and is accessible.

Despite these steps, DeepStream does not process the config-file-path, and the pipeline fails to use my custom configuration file for streammux.

My Questions:

1. Is the config-file-path key supported in DeepStream 7.1 for the [streammux] section?
2. If supported, what could be causing this warning and how can I fix it?
3. If not supported, what is the recommended approach to load custom configurations for streammux?

Any guidance or suggestions would be greatly appreciated. Thank you!

Additionally, I have set the environment variable using the following command before running DeepStream:
export USE_NEW_NVSTREAMMUX=yes
However, when I run the DeepStream application, I receive the following warning:
** WARN: <parse_streammux:821>: Unknown key 'config-file-path' for group [streammux]

config-file-path

There are two solutions you can try for now.

1. modify the config-file-path to the config-file in your config file
2. modify the source code #define CONFIG_GROUP_STREAMMUX_CONFIG_FILE_PATH "config-file-path" in the deepstream_config_file_parser.c

We will also fix it in the next release.
