iRTSP

iRTSP turns your iPhone into a professional RTSP camera server. Stream your camera and microphone live over your local network to any standard player — VLC, ffmpeg, OBS, Blender, or your own code — with a full suite of time-synchronized sensor channels for robotics, AR, and computer-vision work.

STREAMING

• Standard RTSP (RFC 2326) server — connect from VLC, ffmpeg, OBS, or any RTSP client
• H.264 or HEVC video with AAC audio and RTCP audio/video sync
• Front or back cameras, multi-lens zoom
• Optional username / password authentication
• Bonjour discovery — the app shows its rtsp:// URL and a scannable QR code

PRO CAMERA CONTROLS

• Manual ISO, shutter, focus, white balance, and exposure
• AF / AE / AWB locks, EV compensation, torch control
• Apple Log on supported devices
• Save and recall named, color-coded camera profiles

SENSOR DATA FOR VIO / ROBOTICS / AR (all opt-in)

• IMU: accelerometer, gyroscope, and fused device motion, with live camera intrinsics
• GPS location, compass heading, and barometric altitude
• LiDAR metric depth on Pro devices
• ARKit 6DOF world-tracking pose

Every stream is time-stamped against the same clock as the video, so the data lines up frame-for-frame.

PRIVACY
Everything streams peer-to-peer on your own Wi-Fi or hotspot. No account, no cloud, no data collection — nothing ever leaves your local network.

iRTSP is built for makers, researchers, and anyone who needs a high-quality, low-latency iPhone camera and sensor feed.

Lens calibration for computer-vision users: recorded takes can now include Apple's per-frame lens distortion data and the capture state as actually applied, so footage can be undistorted accurately. A one-tap calibration harvest records a matched pair of formats with a driven focus sweep and cross-checks them.

New path comparison: one tap records the standard camera path and the ARKit pose path back to back so their lens geometry can be compared directly. A landscape aiming guide checks that the phone is steady, that depth can see the scene, and that the frame corners hold straight edges (checkerboards, tiles and window grids all count), drawing the detected edges where they actually are before you start.

Rolling-shutter calibration is easier and more trustworthy: a full-screen live positioning guide shows whether the camera can see the flicker banding before you spend a measurement on it, you can measure just the exact mode you are about to record with, and runs that cannot hold their manual exposure now refuse and say why instead of returning a plausible wrong number.

Exports: device attitude and compass heading now get their own CSV files, ARKit takes report the resolution actually delivered, and burning a sensor overlay into an export no longer distorts the frame-gap report.

Recording fixes: takes now record their true capture settings instead of blanks, a pinned measurement format no longer stretches the video, and passthrough recordings no longer lose the beginning of a take. Codec and capture mode are one setting again, so ProRes takes stop running an encoder they never needed and can reach 10-bit and Log.
