Ovstream

CUDA buffer allocation, pitch alignment, BGRA channel order, and ctypes-bound cudart usage. Use when user asks about CUDA interop, pitched allocations, frame layout, or zero-copy GPU integration.

Writing an SHM reader/consumer that attaches to an ovstream SHM producer. Use when user asks about consuming SHM frames, reading from shared memory, writing an OpenCV / Electron / custom viewer, or multi-reader patterns.

Error checking patterns for both C and Python plus logging. Use when user asks about error handling, debugging ovstream failures, registering a log callback, or troubleshooting.

Setting up a new CMake C/C++ project that uses ovstream. Use when user asks to create a new C project, set up CMake with ovstream, scaffold a C++ streaming app, or configure build dependencies.

Creating and configuring an ovstream server instance. Use when user asks to create a server, configure ports, set up a streaming endpoint, or pick between server types.

High-level overview of a typical ovstream application lifecycle. Use when user asks how to structure an ovstream program, what the main steps are, or how the pieces fit together.

Writing a native (StreamSDK) reader/consumer that attaches to an ovstream NATIVE server over the network. Use when user asks about consuming a native stream, writing a StreamSDK client viewer, decoding frames client-side via NvStreamingMedia, or streaming between two different machines.

Submitting video frames to ovstream (raw CUDA BGRA8 or pre-encoded bitstreams). Use when user asks how to push frames, the video frame format, pitch alignment, or pre-encoded passthrough.

Writing a CUDASHM reader/consumer that attaches to an ovstream CUDASHM producer over CUDA IPC. Use when user asks about consuming GPU-resident frames, reading from a CUDA IPC ring, writing a simulation/post-processing kernel that ingests rendered output, or running a consumer in a separate container.

Choosing between WebRTC, RTSP, the native protocol, SHM, and CUDASHM. Use when user asks which transport to use, the trade-offs, what each protocol supports, or how to view a stream.

Wiring connection / message / input callbacks for WebRTC, native, SHM, and CUDASHM streams. Use when user asks about receiving input events, handling messages, detecting client connect/disconnect, or sending messages back.

Setting up a new Python project that uses ovstream. Use when user asks to create a new Python project, set up ovstream in Python, create a pyproject.toml, or scaffold a streaming app.

Diagnose ovstream WebRTC/native connection failures from logs. Use when a client can't connect, the stream is black, a connection times out, or you need to reason about STUN/TURN/ICE/NAT/firewall/container/cloud topology, signaling timeouts, or "what does this StreamSDK error code mean".
