This page serves as a guide to test the GstCUDA evaluation binary provided by RidgeRun.
Requesting the Evaluation Binary
In order to request an evaluation binary for a specific architecture, please contact us providing the following information:
- Platform (i.e.: TX1, TX2)
- gst-launch-1.0 --gst-version
- uname -a
- Jetpack and L4T version
Features in the Evaluation Version
The GstCUDA evaluation version contains all the features of the full version, but with the exception that is limited to only process 600 frames as maximum. Also, it is provided in a binary way, so you won't have access to the source code.
The 600 frames maximum processing limitation allows to test GstCUDA for 10 seconds on a 60fps pipeline, or for 20 seconds on a 30fps pipeline.
The following table summarizes the features available in both the professional and evaluation version of the element.
| Feature | Professional | Evaluation |
|---|---|---|
| cudafilter Element | Y | Y |
| cudaexamplefilter Element | Y | Y |
| CUDA algorithm examples Library | Y | Y |
| Unlimited Processing Time | Y | N (1) |
| Source Code | Y | N |
Testing the Binary
First, make sure the dependencies are fulfilled:
sudo apt-get install \ libgstreamer1.0-dev \ libgstreamer-plugins-base1.0-dev \ gstreamer1.0-plugins-base \ libgstreamer-plugins-bad1.0-dev \ gstreamer1.0-plugins-bad \ libegl1-mesa-dev \ gtk-doc-tools
Also, be sure that [CUDA L4T package] is successfully installed.
To use the binary provided by RidgeRun, export the location of the evaluation binary in your environment.
export GST_PLUGIN_PATH=${GST_PLUGIN_PATH}:/path/to/evaluation/binary/
where /path/to/evaluation/binary is the location in your file system where you have the binary provided by RidgeRun.
Additionally, you may just copy the binaries into the standard GStreamer plug-in search path as the follow instructions:
cp XXX YYY
Finally, test that the plugin is being properly picked up by GStreamer by running:
$ gst-inspect-1.0 cuda Plugin Details: Name cuda Description Allows frames to be processed by the GPU using a custom CUDA library algorithm Filename /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstcuda.so Version 0.2.2.1 License Proprietary Source module gst-cuda Source release date 2017-11-27 21:03 (UTC) Binary package GStreamer CUDA Plug-in Origin URL Unknown package origin cudafilter: cudafilter 1 features: +-- 1 elements
$ gst-inspect-1.0 | grep cuda cudaexamplefilter: cudaexamplefilter: GstCUDA Example Filter Element cuda: cudafilter: cudafilter
You should see the inspect output for the evaluation binary as shown above.
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.
If the plug-in is not being recognized, please provide the output of the following command:
gst-inspect-1.0 libgstcuda.so
