# DeepStream Development Skill When this skill is active, **ALWAYS read the relevant reference documents** before generating code. Do NOT rely on memory - the reference documents contain critical details about exact property names, correct API usage, and common pitfalls. ## SDK and Architecture Quick Reference ### DeepStream SDK Version Requirements - **GStreamer**: 1.24.2 - **NVIDIA Driver**: 590+ - **CUDA**: 13.1 - **TensorRT**: 10.14.1.48 - **Platforms**: Ubuntu 24.04 (x86_64 and ARM64/Jetson) ### Typical Pipeline Flow ``` Source → Stream Muxer → Inference → [Tracker] → OSD → Renderer ``` Components in `[brackets]` are **optional** -- only add them when the user explicitly requests them. | Stage | Role | Key Element(s) | Required? | |-------|------|-----------------|-----------| | Source | Input from files, RTSP, cameras | `nvurisrcbin` (preferred), `nvmultiurisrcbin`, `filesrc` | Yes | | Stream Muxer | Batches streams for inference | `nvstreammux` | Yes | | Inference | TensorRT model execution | `nvinfer`, `nvinferserver` | Yes | | Tracker | Multi-object tracking across frames | `nvtracker` | **Only if requested** | | OSD | Draws bounding boxes, labels, overlays | `nvosdbin` | Yes (for visualization) | | Renderer | Display or save output | `nveglglessink`, `nv3dsink`, `filesink` | Yes | ### Memory Model DeepStream uses NVIDIA Video Memory Manager (NVMM) for zero-copy GPU buffer transfers. Caps strings use `memory:NVMM` to indicate GPU memory (e.g., `video/x-raw(m...
