NNStreamer is an efficient and flexible stream pipeline framework for complex neural network applications. It was initially developed by Samsung and then transferred to LF AI Foundation as an incubation project.
NNStreamer: Efficient and Flexible Stream Pipeline
Framework for Complex Neural Network Applications
NNStreamer provides a set of GStreamer plugins so developers may apply neural networks, attach related frameworks (including ROS, IIO, FlatBuffers, and Protocol Buffers), and manipulate tensor data streams in GStreamer pipelines easily and execute such pipelines efficiently.
It has already been adopted by various Android and Tizen devices in Samsung, which implies that it is reliable and robust enough for commercial products. It supports well-known neural network frameworks including Tensorflow, Tensorflow-lite, Caffe2, PyTorch, OpenVINO, ARMNN, and NEURUN. Users may include custom C functions, C++ objects, or Python objects as well as such frameworks as neural network filters of a pipeline in run-time. Users may also add and integrate support for such frameworks or hardware AI accelerators in run-time, which may exist as independent plugin binaries.
NNStreamer’s official binary releases include supports for Tizen, Ubuntu, Android, macOS, and Yocto/OpenEmbedded; however, as long as the target system supports GStreamer, it should be compatible with NNStreamer as well. We provide APIs in C, Java, and .NET in case GStreamer APIs are overkill. NNStreamer APIs are the standard Machine Learning APIs of Tizen and various Samsung products as well.
sudo add-apt-repository ppa:nnstreamer/ppa
sudo apt-get update
sudo apt-get install nnstreamer nnstreamer-caffe2 nnstreamer-tensorflow nnstreamer-tensorflow-lite
Tizen 5.5 or Higher
Use Machine-Learning Inference APIs (Native / .NET) to use NNStreamer in Tizen applications.
Use JCenter repository to use NNStreamer in Android Studio.
OpenEmbedded’s meta-neural-network layer has NNStreamer included.
MacOS users may install NNStreamer via Brew taps or build NNStreamer for their own systems.
In general, you may build NNStreamer in any GStreamer-compatible systems.
