Capture

Frames in GPU memory, in your first session. Bring RTSP, ONVIF, Analog HD / TVI, SDI, and multimedia files into your application through compatible YUAN hardware. Capture frames for recording, streaming, and AI analysis.

Source to output

Keep the frameon the fast path.

Combine IP camera feeds with Analog HD inputs, including TVI, and digital SDI sources through compatible YUAN capture hardware. Confirm the interface, channel count, and target platform during evaluation. GPUDirect DMA provides a GPU-memory capture path on supported configurations.

YUAN’s Capture module page states: “only 4 APIs, allowing you to capture video and audio within just five minutes.”

Capture capabilities

Move the frame. Keep control.

Hybrid inputs

Connect IP, Analog HD, and SDI sources

Use RTSP and ONVIF network cameras alongside Analog HD / TVI capture and digital SDI inputs. Select the YUAN capture card or module for each interface, then feed the video into your application’s recording, streaming, and analysis workflow.

GPU path

Capture into GPU memory

NVIDIA GPUDirect enables high-performance DMA capture direct to GPU memory. It removes a later memory-transfer step from the pipeline.

Render + compose

Shape the frame before output

ThumbDraw supports multi-screen rendering. Adjust brightness, hue, contrast, and saturation. Scale, crop, and rotate with CPU or GPU processing.

Workflow depth

Carry overlays and imaging data

Use ChromaKey, OSD, layouts, and XML-driven animation. DICOM, PACS, WORKLIST, and HL7 support clinical imaging workflows.

Published surface

Three input paths. Four referenced frameworks.

Network inputs include RTSP and ONVIF. Analog HD / TVI and digital SDI inputs use compatible capture hardware. Exact interface, framework, and operating-system combinations are confirmed during evaluation; the per-input compatibility matrix remains pending publication.
