This page provides a guide to installing GstNvStabilize.
Dependencies
Start by making sure the following dependencies are installed.
- GStreamer 1.14 or greater development packages[1]
- libgstreamer1.0-dev
- libgstreamer-plugins-base1.0-dev
- libcpputest-dev
- CUDA 10.0 or greater[1][2]
- VisionWorks 1.6 or greater[1][2]
Linux
In Debian based systems, you may install the development packages by running the following command:
sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libcpputest-dev
CUDA deviceQuery
CUDA has a utility called "deviceQuery". I order to meet that dependency, you have to follow these steps:
- cd /usr/local/cuda/samples/1_Utilities/deviceQuery # This path may change accordingly to your CUDA installation (this is the deafult)
- sudo make
- # The de "deviceQuery" utility will be ready to use. Test it by executing it as follows: ./deviceQuery
Building the Plug-in
This configuration has been tested on Jetson TX2, Nano and Xavier.
./autogen.sh --prefix /usr/ --libdir /usr/lib/aarch64-linux-gnu/ make sudo make install
Verify Proper Installation
The plugin installation can be verified by running:
gst-inspect-1.0 nvstabilize
Troubleshooting
The first level of debug to troubleshoot a failing pipeline is to inspect GStreamer debug output.
GST_DEBUG=2 gst-launch-1.0 videotestsrc ! nvstabilize ! fakesink
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 /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstnvstabilize.so
No GPU Detected
If you get a configuration error like the following, where no GPU is being detected:
configure: Setting platform preference to: "auto" checking for nvcc... /usr/local/cuda/bin/nvcc checking for /usr/local/cuda/lib64... yes checking size of long... 8 checking for cuda.h... yes configure: GPU test result: FAIL configure: error: The system does not have GPU [AUTOGEN][10:25:21][ERROR] Failed to run configure
Please check if the Jetson TX2/Nano/Xavier was able to load the modules located at /lib/modules. This issue happens when the GPU modules have not been loaded.
