ovstream

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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".
