Introduction
The following guide pretends to ease the installation process of all the dependencies necessary to execute Ridgerun's GStreamer Based Image Signal Processor plugin.
OpenCL
Desktop
Intel OpenCL Support Ubuntu
1. Install lsb-core OpenCL prerequisite
sudo apt-get install -y lsb-core
2. Download the required OpenCL Runtime for Intel Core according to your platform
For example for Ubuntu 18.04/20.04 the following commands can be used (obtained from latest release):
mkdir tmp-opencl && cd tmp-opencl wget https://github.com/intel/compute-runtime/releases/download/20.42.18209/intel-gmmlib_20.3.2_amd64.deb wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.5186/intel-igc-core_1.0.5186_amd64.deb wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.5186/intel-igc-opencl_1.0.5186_amd64.deb wget https://github.com/intel/compute-runtime/releases/download/20.42.18209/intel-opencl_20.42.18209_amd64.deb wget https://github.com/intel/compute-runtime/releases/download/20.42.18209/intel-ocloc_20.42.18209_amd64.deb wget https://github.com/intel/compute-runtime/releases/download/20.42.18209/intel-level-zero-gpu_1.0.18209_amd64.deb
3. Install all the required packages
sudo dpkg -i *.deb
4. Install headers
sudo apt install opencl-headers
i.MX based
When building the system for i.MX platforms the MetaRidgerun layer contains the required recipes for gst-isp and gst-opencl which will install all the required dependencies.
 | Note: For i.MX6: i.MX6 platforms do not support atomic operators, so the --disable-atomics should be appended to the configure options. |
Qualcomm RB5/RB6
The Linux Ubuntu (LU) image is already equipped with OpenCL. You don't need additional steps and you can compile on host.
GStreamer Plugin
RidgeRun will provide the sources required to build the project.
To compile and install for Desktop run the following commands:
Gst-opencl
cd gst-opencl
./autogen.sh --libdir=/usr/lib/$(uname -m)-linux-gnu
./configure --libdir=/usr/lib/$(uname -m)-linux-gnu
make
sudo make install
Gst-isp
cd gst-isp
./autogen.sh --libdir=/usr/lib/$(uname -m)-linux-gnu
make
sudo make install
