Intel® Deep Learning Streamer (Intel® DL Streamer) Pipeline Framework is an open-source streaming media analytics framework, based on GStreamer* multimedia framework, for creating complex media analytics pipelines for the Cloud or at the Edge.

Media analytics is the analysis of audio & video streams to detect, classify, track, identify and count objects, events and people. The analyzed results can be used to take actions, coordinate events, identify patterns and gain insights across multiple domains: retail store and events facilities analytics, warehouse and parking management, industrial inspection, safety and regulatory compliance, security monitoring, and many other.

Intel® DL Streamer Pipeline Framework is optimized for performance and functional interoperability between GStreamer* plugins built on various backend libraries

• Inference plugins use OpenVINO™ inference engine optimized for Intel CPU, GPU and VPU platforms
• Video decode and encode plugins utilize GPU-acceleration based on VA-API
• Image processing plugins based on OpenCV and DPC++
• Hundreds other GStreamer* plugins built on various open-source libraries for media input and output, muxing and demuxing, decode and encode

2. Run Docker image
3. Compile from source code
4. Build Docker image from source code

Samples available for C/C++ and Python programming, and as gst-launch command lines and scripts.

Intel® DL Streamer supports NN models in OpenVINO™ IR and ONNX* formats:

• Refer to OpenVINO™ Model Optimizer how to convert model into OpenVINO™ IR format
• Refer to training frameworks documentation how to export model into ONNX* format

Or you can start from over 70 pre-trained models in OpenVINO™ Open Model Zoo and corresponding model-proc files (pre- and post-processing specification) in /opt/intel/dlstreamer/samples/model_proc folder. These models include object detection, object classification, human pose detection, sound classification, semantic segmentation, and other use cases on SSD, MobileNet, YOLO, Tiny YOLO, EfficientDet, ResNet, FasterRCNN and other backbones.
