StudyCast

StudyCast is a macOS multi-device AirPlay capture desk for research sessions, teaching labs, and product demos.

It runs one AirPlay receiver per station, shows local previews, routes monitoring audio per station, and saves MP4 recordings for each connected device.

Status

StudyCast is an early beta. It is useful for controlled local-network sessions, but it is not production broadcast software and does not try to replace commercial AirPlay receivers.

The first binary release targets Apple Silicon Macs on macOS 26 or newer. Older macOS versions may work from source, but they are not covered by the downloadable beta.

Features

• Run 1 to 8 AirPlay receiver stations from one macOS app.
• Preview each device stream in a responsive SwiftUI grid.
• Start and stop recording intervals while projection continues.
• Save per-station master recordings and trimmed MP4 clips.
• Select a monitoring audio output per station.
• Bundle UxPlay, GStreamer, ffmpeg, and ffprobe for release builds.

Try StudyCast

StudyCast currently offers two beta paths.

Option 1: Build from source

This is the most transparent path for developers and security-sensitive users. See docs/INSTALL.md.

Quick path:

brew install gstreamer ffmpeg
export UXPLAY_SOURCE_DIR=/path/to/UxPlay
export UXPLAY_PATH="$UXPLAY_SOURCE_DIR/uxplay"
xcodebuild -project StudyCast.xcodeproj -scheme StudyCast -configuration Debug -destination 'platform=macOS' CODE_SIGNING_ALLOWED=NO build

Option 2: Unsigned preview DMG

For users who want the easiest install path today, GitHub Releases may include StudyCast-0.1.0-beta.1-arm64-unsigned.dmg.

This preview DMG is ad-hoc signed but not Apple Developer ID signed or notarized. StudyCast does not yet have a paid Apple Developer Program account, so macOS Gatekeeper will ask you to approve it manually in System Settings > Privacy & Security after the first launch attempt.

1. Download StudyCast-0.1.0-beta.1-arm64-unsigned.dmg.
2. Open the DMG and drag StudyCast into Applications.
3. Launch StudyCast once. If macOS blocks it, open System Settings > Privacy & Security and choose Open Anyway.
4. Relaunch StudyCast and allow Local Network access.
5. Click Start Projection, then choose a StudyCast-N AirPlay target from each device.
6. Click Start Recording and Stop Recording to mark clips.
7. Click Stop Projection to finalize the MP4 files.
