GstNetBalancer - Evaluating the balancer

Requesting the Evaluation Binary

RidgeRun can provide you with an evaluation binary of the Stitcher to help you test it, in order to request an evaluation binary for a specific architecture, please contact us providing the following information:

Platform (i.e.: NVIDIA Jetson TX1/TX2, Xavier, Nano, or x86)
Jetpack version
Input resolutions and frame rates
Expected output resolution and frame rate
Latency requirements

Features of the Evaluation

To help you test our NetBalancer, RidgeRun can provide an evaluation version of the plug-in.

The following table summarizes the features available in both the professional and evaluation version of the element.

Table 1. Features provided in the evaluation version
Feature	Professional	Evaluation
GstNetBalancer Element	Y	Y
Unlimited Processing Time	Y	N (1)
Source Code	Y	N

(1) The evaluation version will limit to 5 minutes of processing.

Installing the evaluation version

Once the evaluation binaries are requested RidgeRun will provide you with a compressed tar package containing the element library.

Dependencies

The GstNetBalancer evaluation has the following dependencies:

GStreamer

The GStreamer packages are likely already installed in your Ubuntu OS distribution. In case you want to double-check and install the missing packages, run the following commands.

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-bad

Eval binaries structure

First extract the package contents with the following command:

tar xvzf <path-to-evaluation-tar-file>

The package structure should look like the following:

For x86

usr/
└── lib
    └── x86_64-linux-gnu
        └── gstreamer-1.0
            └── libgstnetbalancer.so

For Jetson

usr/
└── lib
    └── aarch64-linux-gnu
        └── gstreamer-1.0
            └── libgstnetbalancer.so

Binaries installation

For x86

export GST_PLUGIN_PATH=${GST_PLUGIN_PATH}:${PATH_TO_EVALUATION_BINARY}/usr/lib/x86_64-linux-gnu/gstreamer-1.0/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${PATH_TO_EVALUATION_BINARY}/usr/lib/x86_64-linux-gnu/

where PATH_TO_EVALUATION_BINARY is set the location in your file system where you have stored the binary provided by RidgeRun.

Alternatively, you may just copy the binaries into the standard GStreamer plug-in search path:

sudo cp -r ${PATH_TO_EVALUATION_BINARY}/usr /

For Jetson

export GST_PLUGIN_PATH=${GST_PLUGIN_PATH}:${PATH_TO_EVALUATION_BINARY}/usr/lib/aarch64-linux-gnu/gstreamer-1.0/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${PATH_TO_EVALUATION_BINARY}/usr/lib/aarch64-linux-gnu/

where PATH_TO_EVALUATION_BINARY is set the location in your file system where you have stored the binary provided by RidgeRun.

Alternatively, you may just copy the binaries into the standard GStreamer plug-in search path:

sudo cp -r ${PATH_TO_EVALUATION_BINARY}/usr /

Eval Binaries Testing

Finally, test that the plugin is being properly picked up by GStreamer by running:

gst-inspect-1.0 netbalancer

You should see the inspect output for the evaluation binary as shown below.

Example Pipelines

Please refer to the Examples page for reference pipelines.

Troubleshooting

The first level of debug to troubleshoot a failing evaluation binary is to inspect GStreamer debug output.

GST_DEBUG=2 gst-launch-1.0

If the output doesn't help you figure out the problem, please contact support@ridgerun.com with the output of the GStreamer debug and any additional information you consider useful.

RidgeRun also offers professional support hours that you can invest in any embedded Linux-related task you want to assign to RidgeRun, such as hardware bring-up tasks, application development, GStreamer pipeline fine-tuning, drivers, etc...
