DeepStream Python Apps
This repository contains Python bindings and sample applications for the DeepStream SDK.
The bindings and apps are currently in Alpha at v0.9. The API is maturing but changes are still expected.
SDK version supported: 5.0 Developer Preview
Download the latest release package complete with bindings and sample applications from the release section.
Please report any issues or bugs on the Deepstream SDK Forums.
Python Bindings
DeepStream pipelines can be constructed using Gst Python, the GStreamer framework's Python bindings. For accessing DeepStream MetaData, Python bindings are provided in the form of a compiled module. Download these bindings here. This module is generated using Pybind11.
These bindings support a Python interface to the MetaData structures and functions. Usage of this interface is documented in the HOW-TO Guide and demonstrated in the sample applications.
This release adds bindings for decoded image buffers (NvBufSurface) as well as inference output tensors (NvDsInferTensorMeta).
Sample Applications
Sample applications provided here demonstrate how to work with DeepStream pipelines using Python.
The sample applications require MetaData Bindings to work.
To run the sample applications or write your own, please consult the HOW-TO Guide
We currently provide the following sample applications:
- deepstream-test1 -- 4-class object detection pipeline
- deepstream-test2 -- 4-class object detection, tracking and attribute classification pipeline
- deepstream-test3 -- multi-stream pipeline performing 4-class object detection
- deepstream-test4 -- msgbroker for sending analytics results to the cloud
- deepstream-imagedata-multistream -- multi-stream pipeline with access to image buffers
- deepstream-ssd-parser -- SSD model inference via Triton server with output parsing in Python
- deepstream-test1-usbcam -- deepstream-test1 pipelien with USB camera input
- deepstream-test1-rtsp-out -- deepstream-test1 pipeline with RTSP output
Detailed application information is provided in each application's subdirectory under apps.
