TI GStreamer Plugins

Repository to host GStreamer plugins for TI's EdgeAI class of devices

Building the Project

The project can be either be built natively in the board, or cross compiled from a host PC.

Cross Compiling the Project

# Load the PSDKR path
PSDKR_PATH=/path/to/the/ti-processor-rsdk

# Customize build for your SDK
PKG_CONFIG_PATH='' crossbuild/environment $PSDKR_PATH > aarch64-none-linux-gnu.ini

# Configure and build the project
PKG_CONFIG_PATH='' meson build --cross-file aarch64-none-linux-gnu.ini --cross-file crossbuild/crosscompile.ini
ninja -C build
DESTDIR=$PSDKR_PATH/targetfs ninja install

Compiling the Project Natively

meson build --prefix=/usr -Dpkg_config_path=pkgconfig
ninja -C build
ninja -C build test
ninja -C build install
ldconfig

You can delete the GStreamer registry cache if the new elements are not found using gst-inspect and build a new one

rm -rf ~/.cache/gstreamer-1.0/registry.aarch64.bin
gst-inspect-1.0

Compiling the Project Natively inside the PSDK RTOS Docker container

#Build Docker container
cd /opt/edgeai-gst-apps/docker
./docker_build.sh
./docker_run.sh
cd /opt/edgeai-gst-apps
./docker_run.sh

#Build the tiovx modules
cd /opt/edgeai-tiovx-modules/build
cmake ..
make -j$(nproc)
make install

#Build the GStreamer plugin (same as native build)
meson build --prefix=/usr -Dpkg_config_path=pkgconfig
ninja -C build
ninja -C build install

#Test plugin is loaded correctly
gst-inspect-1.0 tiovx
gst-inspect-1.0 ti

GStreamer plugins

GstTIOVX

These are plugins which internally uses TIOVX (TI's implementation of OpenVX). These plugins are compiled for devices which have OpenVX support. Eg: TDAV4M,AM68A,AM69A,AM62A etc.

GstTI

These are the arm-only plugins which internally uses Arm NEON optimized kernels. This plugins can be built on any device with gstreamer support. Eg: AM62X, AM62P.
