SRT Mirror

An Android TV app that receives SRT video streams via SRTDroid and plays them in real time using ExoPlayer. Point an SRT source (e.g. OBS) at your TV and it mirrors the stream full-screen.

Requirements

• Android TV device or emulator with ARM support (x86 emulators are not supported)
• Android 7.0 (API 24) or higher

Building

./gradlew assembleDebug

./gradlew assembleRelease

Requires JDK 21.

Usage

1. Install the APK on your Android TV device
2. Open SRT Mirror — it will display the device's local IP and the listen port
3. In OBS (or any SRT-capable tool), set the output to SRT with the URL:

srt://<tv_ip>:<port_number>?mode=caller

4. Start streaming — the TV will automatically connect and display the feed full-screen

To change the listen port, navigate to Settings from the waiting screen.
