Written in C++ 17 with an `extern "C"` API, The DeepStream Services Library (DSL) can be called from both C/C++ and Python applications. ## Examples ### C++ ```C++ #include // New V4L2 Source uint retval = dsl_source_v4l2_new(L"my-web-cam-1", L"/dev/video0"); ``` ### Python3 ```Python from dsl import * # New V4L2 Source retval = dsl_source_v4l2_new('my-web-cam-1', '/dev/video0') ``` DSL is built on the NVIDIA® [DeepStream SDK](https://developer.nvidia.com/deepstream-sdk), _"A complete streaming analytics toolkit for AI-based video and image understanding, as well as multi-sensor processing."_, The DeepStream SDK and DSL use the open source [GStreamer](https://gstreamer.freedesktop.org/),  _"An extremely powerful and versatile framework for creating streaming media applications"_. --- ## Contributing DSL is released under the [MIT License](LICENSE). Contributions are welcome and greatly appreciated. Please review our [code of conduct](/CODE_OF_CONDUCT.md). ***Please report issues!*** ## DSL Branching Workflow 1. `Master` is always the latest release and is only updated once per release. 2. `Develop` is the next release currently in development. The branch will be named with the next release label. 3. `Feature` all work is done on feature branches, named for the feature under development. All pull requests should be made against the current `Develop` branch. ## Discord Come join us on [Discord](https://discord.gg/MJvY9jjpAK), an informal place to chat, ask questions, discuss ideas, etc. ## DSL Users Guide * [Release Notes](/Release%20Notes/dsl-releases.md) * [Overview](/docs/overview.md) * [Installing Dependencies](/docs/installing-dependencies.md) * [Building and Importing DSL](/docs/building-dsl.md) * [API Reference](/docs/api-reference-list.md) * [Pipeline](/docs/api-pipeline.md) * [Player](/docs/api-player.md) * [Source](/docs/api-source.md) * [Tap](/docs/api-tap.md) * [Video Dewarper](/docs/api-dewarper.md) * [Preprocessor](/docs/api-preproc.md) * [Inference Engines and Servers](/docs/api-infer.md) * [Multi-Object Tracker](/docs/api-tracker.md) * [Segmentation Visualizer](/docs/api-segvisual.md) * [Tiler](/docs/api-tiler.md) * [Demuxer and Splitter](/docs/api-tee.md) * [Remuxer](/docs/api-remuxer.md) * [On-Screen Display](/docs/api-osd.md) * [Sink](/docs/api-sink.md) * [Branch](/docs/api-branch.md) * [Component](/docs/api-component.md) * [Custom Component](/docs/api-gst.md) * [Pad Probe Handler](/docs/api-pph.md) * [ODE Trigger](/docs/api-ode-trigger.md) * [ODE Accumulator](/docs/api-ode-accumulator.md) * [ODE Acton](/docs/api-ode-action.md) * [ODE Area](/docs/api-ode-area.md) * [ODE Heat-Mapper](/docs/api-ode-heat-mapper.md) * [Display Type](/docs/api-display-type.md) * [Mailer](/docs/api-mailer.md) * [WebSocket Server](/docs/api-ws-server.md) * [Message Broker](/docs/api-msg-broker.md) * [Info API](/docs/api-info.md) * [Examples](/docs/examples.md) * [Basic Inference Pipelies](/docs/examples-basic-pipelines.md) * [Multiple Sources, Tilers, and Demuxers](/docs/examples-sources-tiler-demuxer.md) * [Advanced Inference Pipelies](/docs/examples-advanced-pipelines.md) * [Smart Recording](/docs/examples-smart-recording.md) * [Object Detection Event (ODE) Services](/docs/examples-ode-services.md) * [Encoding Frames to JPEG](/docs/examples-encode-and-save-frame.md) * [Dewarping and Segmentation](/docs/examples-dewarping-and-segmentation.md) * [Dynamic Pipelines](/docs/examples-dynamic-pipelines.md) * [Custom Components](/docs/examples-custom-components.md) * [Working with OpenCV](/docs/examples-opencv.md) * [Diagnostics and Utilites](/docs/examples-diagnaostics-and-utilities.md) * [Tkinter Reference App](/docs/examples-tkinter.md) * [HTML WebRTC Client](/docs/examples-webrtc-html.md) * [Using VS Code](/docs/vscode.md) * ```` --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/tools/prominenceai-deepstream-services-library`](/api/graphcanon/tools/prominenceai-deepstream-services-library) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
