Brix

Free and open IRL streaming from your phone, on the move
New in version 0.2.1-beta
Kick chat: updated Pusher app key; the old one is rejected by the server, chat did not connect in 0.2.0.
Mic level meter: segmented bars next to the mute slot; clipping held for 1.5 s; level shown grey while muted (measured before mute, stream stays silent); updates capped at 10 Hz.
Link import: only one server stays active after importing a brix:// or moblin:// link.
About: licence corrected to GPL-3.0.
A free app for streaming from your phone while you move around. It publishes to Twitch and to any server that speaks RTMP, SRT or WHIP.

And when one network isn't enough, it can bond several links into a single stream, so the broadcast survives the walk from Wi-Fi to cellular instead of falling apart on the way. That part needs your own SRTLA-capable receiver.

An open alternative to the closed IRL apps on Android.

THIS IS A BETA

It works and has been used on air, but on a single device — a Samsung S21. Untested: MP4 recording over long sessions, Moblink with a real second phone. WHIP sometimes fails to connect on the first try — starting again helps. A Bluetooth headset microphone does not work yet: recording stays on the built-in one. The full list of limitations is in the project description on GitHub.

TRANSPORT

* SRTLA — bonds several links into one stream. The SRT and SRTLA client is written from scratch, not a wrapper around someone else's library.
* Plain SRT for receivers without SRTLA; the URL scheme picks the mode.
* RTMP and WHIP for when bonding isn't needed.
* Per-link priorities and weights, reconnect after a drop.
* Adaptive bitrate: RTT and its jitter, send buffer size, window-forced losses. Three aggressiveness profiles.

VIDEO AND AUDIO

* 720p and 1080p, H.264 and HEVC, hardware encoder.
* Scenes: camera, a "be right back" still, or screen capture. Each carries its own overlays, camera side and audio mode.
* Lens selection, zoom, torch, tap to focus, optical and electronic stabilisation controlled separately.
* Microphone selection: built-in, wired or USB.
* On-screen microphone level meter: clipping and mute are visible at a glance.
* A first-run wizard; settings offer only the capture modes your phone actually supports.

AUDIENCE

* Twitch, Kick and VK Video Live chat in one feed, anonymously, with emotes. Shown to the streamer only, never in the stream.
* Donation overlays for DonationAlerts, DonatePay, iHAQ, Donatty and donate.stream: image and caption drawn straight into the frame, with the donation sound optionally mixed in.
* Any web page as a source of picture in the frame.

ALSO

* Moblink: another phone contributes its link as an extra uplink.
* MP4 recording alongside the broadcast, from the same encoder.
* Configurable HUD and quick buttons on the streamer screen.
* Session log: power, temperature and transport figures once per second, for outings where no debugger can be attached.

REQUIREMENTS

Android 10 or newer and a hardware encoder. Bonding needs a receiver that speaks SRTLA and several networks at once.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
