Multi-camera church streaming, run from one iPad

Why small churches struggle to stream well

Most small churches stream with one fixed camera and the sanctuary’s sound mix, because the alternative costs more money and more volunteers than they have. A hardware switcher, capture cards, a streaming computer and someone trained to run them add up quickly.

The sound is usually the bigger problem. The mix that works in the room is built for the room: loud instruments are turned down because they are already loud acoustically, and microphones are set for speakers, not headphones. Sent straight to YouTube, the same mix sounds thin and uneven to the people watching at home.

Then there is Sunday morning itself, when small mistakes become public: a stream key pasted in the wrong place, Wi-Fi that quietly can’t keep up, or a private service that goes out publicly by accident. This church needed something a volunteer could run with confidence, every week.

How we approached it

We started from what the church already had: a Behringer X32 sound desk, a few iPhones and an iPad. The plan had three steps.

1. Turn phones into cameras. iPhones send video to the iPad over the church’s own Wi-Fi, with tally lights so each operator knows the moment they are live.
2. Mix the stream separately from the room. The iPad takes the raw channels from the X32 and builds its own broadcast mix, with saved presets such as “Sermon” and “Worship.”
3. Make going live boring. The church connects YouTube once on the web. After that, Go Live creates the week’s broadcast by itself.

We tested at the church early. The first end-to-end run, from iPhone camera to iPad to YouTube Live, happened on real devices on July 6, 2026. After that, each round of feedback from the Sunday team became a numbered list of fixes, from scroll-safe faders to a countdown that warns a camera operator before an automatic cut.

How Steeple Cast works

Steeple Cast is one iPhone and iPad app that plays three roles on the church’s own Wi-Fi network, plus a small web dashboard for the YouTube connection. Video goes straight from the iPad to YouTube and never passes through Peace Builders’ servers.

Built with

• Swift and SwiftUI: the native app for iPad and iPhone (iOS and iPadOS 17 or later).
• Apple VideoToolbox: hardware video encoding on each phone and decoding on the iPad, so older iPhones keep up.
• Bonjour: cameras find the director automatically, and nobody types an IP address.
• Apple Accelerate: the 32-channel mix runs as vectorised signal processing, so audio doesn’t stutter.
• HaishinKit: the secure RTMPS publisher that sends the program feed to YouTube Live.
• Firebase and the YouTube Live API: the web dashboard where the church connects its channel once and pairs the iPad with a QR code.

There are no ads, analytics or tracking in the app.

What changed for the church

The church runs its stream from one iPad, with iPhones as the cameras and a sound mix built for the people listening at home, instead of a hardware switcher and a tech booth.

• No stream keys on Sunday morning. Go Live creates the week’s YouTube broadcast, titled from a pattern the church chose, with its privacy setting and thumbnail.
• Private stays private. If YouTube can’t create the broadcast, Steeple Cast stops and asks rather than streaming somewhere else.
• Problems are caught before viewers notice. A plain-language warning appears when the Wi-Fi can’t keep up. A dropped connection resumes the same YouTube video, and a local backup can be uploaded at full quality afterwards.
• The whole building can watch. The service can play on a lobby TV through AirPlay, seconds behind the room instead of a minute behind YouTube.
• One church’s tool became a product. Steeple Cast now has a public site, a setup guide and an App Store release on the way, so other churches can use it too.
