MagerCam turns your Android camera into a Windows 11 webcam — no drivers, with OBS support

⚡ The gist in 5 seconds

• MagerCam shows an Android phone's camera in Windows 11 as a virtual camera called "MagerCam" — no separate driver needed.
• Phone on Android 8.0+, connection over Wi-Fi or USB via ADB, up to four phones at once.
• Installer without a paid code signature: SmartScreen complains, and as of version 1.1.0 the APK is signed with a new key.

🔍 What happened

The Magerko/MagerCam project has been published on GitHub — a set of three parts: an Android app, a Windows program, and an OBS plugin. Ready-made files are in Releases: MagerCam.apk, MagerCam-Windows.zip, MagerCam-OBS-plugin.zip. The repo has 11 commits so far, with android/, windows/, obs-plugin/, docs/, tools/ folders and bat scripts for install and uninstall. The phone needs to run Android 8.0 or newer.

Here's how it works. The app captures via Camera2 and encodes with hardware MediaCodec in H.264/H.265 — up to 4K at 60 fps is claimed, with adaptive bitrate and 48 kHz audio with noise suppression. The Windows component installs to C:\Program Files\MagerCam and registers a virtual camera through Windows 11's built-in mechanism — Media Foundation, MFCreateVirtualCamera. The format is NV12, from 640×360 up to 3840×2160 at 30 and 60 fps. USB mode works via adb forward, and the installer downloads platform-tools from Google's site itself. Pairing is via QR code, with incoming TCP ports 4850–4859 opened in private networks for it. There's also a separate web panel at http://IP:4848/ with MJPEG for VLC and a motion detector.

🧠 Our take

The "phone as a webcam" scheme is as old as DroidCam and Iriun, and that's not news. What's new here is different: the virtual camera is built on Windows 11's native API rather than a DirectShow filter driver. Our assessment — it's precisely the arrival of MFCreateVirtualCamera that removed the main barrier: previously every such project needed a signed driver, and with it all the installation headaches.

For your wallet, it's a direct hit on subscriptions. DroidCam and EpocCam have been asking for money for years to remove watermarks and unlock HD, while this is free, ad-free, and without resolution limits — at least that's what the README says. For people with a phone lying in a drawer, it's a cheap second angle: background blur and face auto-framing are computed on the phone itself, while brightness, contrast, and .cube LUTs are applied on the computer.

We believe streamers and everyone recording in OBS benefit here: the "MagerCam (phone)" source delivers video and audio together with camera controls. The paid alternatives lose out — but only if the project survives to stable releases. 11 commits and a single author so far suggest this is more of a solid beta than a product.

⚠️ What we don't know

There are plenty of weak spots. Nobody has measured latency — "low latency" in the README is not a number. It's unclear whether H.265 actually works in practice or is just a claim on paper, and how the Media Foundation virtual camera behaves in older programs that still look for DirectShow devices. The license type can't be determined from a snippet — a LICENSE file exists, but we haven't seen its text. There are no figures at all on phone load and battery drain in the source. And most importantly — there isn't a single independent test; everything written comes from the project's author.
