How to stream your iPhone with OBS on Windows

Updated 22 October 2026 · AirMirror Pro 3.2.1

The short answer: mirror your iPhone to AirMirror Pro, choose View → OBS Mode, and add the window to OBS as a Window Capture. OBS Mode removes the menus and borders, so the capture is just the phone's screen with nothing to crop. Turn on Loop Audio and OBS's Desktop Audio picks up the phone's sound.

It is free, and there is no capture card and no cable.

What you need

A Windows 10 (version 1809) or Windows 11 PC with AirMirror Pro, free from the Microsoft Store.
OBS Studio.
Your iPhone on the same Wi-Fi network as the PC.

Step by step

Open AirMirror Pro, click Start Receiver, and mirror your iPhone: Control Center → Screen Mirroring → AirMirror Pro.
Turn on Loop Audio (the speaker button) in AirMirror Pro. The phone's sound then plays through the PC, where OBS's Desktop Audio records it.
Choose View → OBS Mode. The menus and bars disappear, and the window opens in the middle of the screen in the phone's exact shape, or in the size you set (below). Esc brings everything back.
In OBS, press + under Sources and choose Window Capture, not Game Capture.
Pick the AirMirror Pro window while OBS Mode is on, and use the settings below.
Go live to Twitch, YouTube or anywhere else OBS streams to, as usual.

OBS settings

These are the settings a real capture was checked with. Help → OBS Setup in AirMirror Pro shows them too.

Window: [AirMirrorPro.exe]: AirMirror Pro - OBS Mode (Esc to exit). The iPhone window has a different name, and picking it captures that window instead.
Capture Method: Windows 10 (1903 and up).
Window Match Priority: Match title, otherwise find window of same type.
Client Area: On, which leaves out the title bar.
Capture Cursor: On, or off to keep the Windows pointer out.

A fixed size, like 1920 x 1080

To fill a 16:9 scene without black bars, set File → Settings… → Windows → OBS Mode size to 1920 × 1080, another preset such as 1280 × 720 or 1080 × 1920, or a custom size. The OBS Mode window then takes exactly that size. Fit decides what happens when the picture's shape differs: Crop to fill leaves no bars, Fit with bars shows the whole picture. A 16:9 video fills a 1920 × 1080 window with no black on any side, because the bars the iPhone sends around it are trimmed first.

Sharper video

OBS records the window at the size it is on screen. With Match device, drag the window taller for more detail. It keeps the phone's shape while you do.

For streamers

Even motion in 60 fps games. Turn on Steady 60 fps in File → Settings… → Mirroring. It adds up to one refresh of delay, about 17 ms, and takes effect after a restart.
Notifications stay off stream (Pro). AirMirror Pro's notification banners are kept out of screen recordings and screen shares. If Windows won't do that on a particular PC, the text reads "Hidden" instead of showing.
Drive the phone from your desk. With iPhone control, your mouse and keyboard work the iPhone without your hands leaving the PC. See how to control your iPhone from your PC.

Questions

Do I need a capture card?

No. The iPhone's screen and sound come over AirPlay on your Wi-Fi network.

Why Window Capture and not Game Capture?

In OBS Mode the window is already exactly the phone's shape. Window Capture takes it as it is, and Game Capture would need cropping.

OBS has no sound from the iPhone.

Turn on Loop Audio (the speaker button) in AirMirror Pro, and check that Desktop Audio is not muted in OBS's mixer.

Is OBS Mode free?

Yes. OBS Mode, mirroring and iPhone control are all free. Pro, $5.99 once, is for unlimited recordings inside AirMirror Pro and for your iPhone's notifications.
