GPU-accelerated dual-fisheye stitching with AI seam detection, WebRTC sub-500ms delivery, and OpenXR headset preview — all in one app. Works with any camera.
Works with any camera — no hardware lock-in
No more stitching workstation + encoder + WebRTC relay glue. Stitch2Stream collapses the entire live VR production stack into a single application.
Proprietary U-Net trained on synthetic + real fisheye data. 94%+ seam confidence. Hot-swappable ONNX model — zero frame drops on reload.
CUDA warp kernel targeting sm_75–sm_120 (RTX 2000–5000 series). Metal on Apple Silicon. OpenCV CPU fallback. 3-tier pipeline, always running at maximum speed.
Sub-500ms end-to-end latency via WebRTC/WHIP to Cloudflare, Twitch WHIP, Millicast, Mux, Akamai, Edgio, or any custom endpoint. RTMP and SRT also supported.
Live VR180 stereo preview directly on Meta Quest via Link or SteamVR. Monitor your stream in headset while it's going out live — no separate device needed.
Real-time object detection with EMA-smoothed yaw auto-correction. Keeps your subject centred automatically. Seam-split warning overlay when tracking confidence drops.
A→B format tetrahedral mic capture, 4-channel AAC embed in MP4 output, binaural headphone monitor. Full spatial audio from capture to delivery.
HLG + PQ/HDR10 tone mapping, HEVC 10-bit local recording with MaxCLL/MaxFALL/peak-nits control, VR spherical metadata, stereo top-bottom side-data.
Synchronized grab()/retrieve() for sub-ms inter-camera skew. cos²-feathered overlap blend. DirectShow / AVFoundation / V4L2. 14 built-in lens profiles.
Public C++ IStitchPlugin and IOutputPlugin APIs. Extend with custom algorithms or output targets. Browse and install plugins directly from the in-app marketplace.
Every competitor targets post-production, requires proprietary hardware, or lacks the real-time streaming capabilities modern VR production demands.
