# DeepStream Pipeline Builder Generate ready-to-run `gst-launch-1.0` pipelines for NVIDIA DeepStream SDK by collecting pipeline requirements through an interactive questionnaire, then assembling the pipeline using a standalone BM25 retrieval backend with structural metadata boosting (similarity search over 270+ verified pipelines, zero external dependencies). ## Prerequisites - **Python:** 3.8+ (stdlib only — no pip packages required) - **DeepStream SDK:** Installed at `/opt/nvidia/deepstream/deepstream/` (for `gst-inspect-1.0` validation and element verification) - **GStreamer:** `gst-launch-1.0` and `gst-inspect-1.0` on `PATH` (installed with DeepStream) - **Platform:** x86 dGPU (T4, A100, L40, RTX, etc.) or aarch64 — Jetson (Orin, Xavier, Nano) / SBSA (Grace, GH200) ## Usage Examples ```text # Fully specified — skips most questions detect and track on 4 rtsp streams and display on jetson # Partially specified — asks remaining questions give me a pipeline to infer on an image # Minimal — asks all 7 questions build a pipeline ``` ## Supported Configurations | Parameter | Options | | --- | --- | | **Input** | Local video (.mp4/.h264/.h265), local image (.jpg/.png), RTSP stream, USB camera, test pattern | | **Inference** | None, primary (nvinfer), primary+secondary, with preprocessor, Triton (nvinferserver) | | **Tracker** | None, NvDCF, IOU, NvSORT, DeepSORT | | **Sink** | Display (dGPU/Jetson), save (JPG/PNG/MP4/H264), RTSP out, fakesink | | **Platform** | x86 dGPU ...
