nnstreamer/nnstreamer-edge: Remote source nodes for NNStreamer pipelines without GStreamer dependencies

Remote source nodes for NNStreamer pipelines without GStreamer dependencies

Developers may provide stream inputs to NNStreamer pipelines from remote nodes with nnstreamer-edge. NNStreamer-edge is designed not to depend on GStreamer and targets to be adopted by general RTOS as well.

If your system can afford running nnstreamer (gstreamer), don't use nnstreamer-edge. Use nnstreamer and gstreamer.

• This should not depend on glib, gstreamer, or nnstreamer
• This should not depend on other heavy-weighted libraries.
• This should be compatible not only with Linux, but also with RTOS and other OS; thus, this should try to stick with C basic libraries and POSIX libraries.
  • However, it may leave empty spaces that can be filled with "wrapper/plugin" for the portability. E.g., I may get too lazy to write communication layers; then, I'll leave it to the users to write down their own communication plugins.
  • This should not rely on Tizen, either. However, Tizen-RT might be considered as the primary target.
• Communication Layers includes:
  • Primary Targets: TCP, User Plugins.
  • Secondary Targets: Flatbuffers

• Note: This simple guide explains how to use NNStreamer-edge on the Ubuntu, but NNStreamer-edge is also available on Tizen, Android and TizenRT.

$ sudo add-apt-repository ppa:nnstreamer/ppa
$ sudo apt-get install nnstreamer-edge
# Download nnstreamer for sample application
(optional) $ sudo apt-get install nnstreamer

# Run MQTT broker
$ sudo systemctl start mosquitto

# cd $NNST_EDGE_ROOT
$ cmake -B build -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib -DENABLE_TEST=ON -DMQTT_SUPPORT=ON
$ make -C build install

# Run test
