Why?
It started with Plex. Every client out there was missing something — Wake-on-LAN for the server, say, or real picture processing with the scalers, upscalers and filters that no other Android TV player offers. So this one has them.
From there the goal grew into an all-in-one app: every video, whatever its source, runs through the renderer of my choice. WireGuard is built in, so the libraries are just as close when I'm away from home. And the good ideas that are usually scattered across half a dozen players finally live together in one place.
Support
Ambient TV is built in spare time, out of love for a good couch evening. If it makes your TV a little nicer, a coffee or a sponsorship helps keep it going — thank you! ☕
Disclaimer
[!WARNING]
Ambient TV is a hobby project, provided as is. Use at your own risk. No responsibility is taken for melting TVs, exploding TV boxes, overheated living rooms or a sudden urge to buy new hardware.
Picture processing is hungry: how well filters, upscalers/shaders, motion smoothing (SVP), deinterlacing, HDR conversion and friends run depends heavily on your hardware. What is silky smooth on one box can turn another into a slideshow (and a space heater). If playback stutters, lower the settings or switch the performance mode to Low.

Requirements
| Requirement | Details |
|---|
| Devices | Android TV / Google TV, phones and tablets with Android API 29+ |
| ABIs | arm64-v8a · armeabi-v7a · x86 · x86_64 |
| Device-dependent | Vulkan output/decoding, SDR → HDR (Android 14+, HDR10 display), passthrough formats, SVP |
| Network | LAN to media servers / NAS; internet for Plex Link, SmartTube, Spotify, trailers |
| Build | JDK 17, Android SDK/NDK (ANDROID_NDK_HOME or ANDROID_NDK_ROOT); optional keystore |
Build
# Debug APK (builds native engines if needed)
./build.sh debug
# Signed release (when keystore.properties is present)
./build.sh release
# Single ABI (ARM TV / devices)
./build.sh arm64
./build.sh armv7
# Emulator ABIs
./build.sh x86
./build.sh x86_64
# Check / update pinned engines
./build.sh libs-check
./build.sh libs-update
Artifacts land under dist/ (e.g. ambient-tv-arm64-<version>.apk, ambient-tv-x86_64-<version>.apk). Pre-release suffixes such as beta, alpha or rc keep the suffix and insert the build number before it (ambient-tv-arm64-1.0.270-beta.apk).
Gradle only (no native preflight): ./gradlew :app:assembleDebug — prefer ./build.sh for product-like builds. SKIP_MPV_NATIVE=1 skips the native MPV build (quick builds/CI), e.g. SKIP_MPV_NATIVE=1 ./gradlew :app:assembleDebug :app:testDebugUnitTest. No Spotify client ID is built in; see Spotify setup.
Details & env vars: docs/DOCUMENTATION.md §14 · EXTERNAL_LIBRARIES.md
The release keystore and keystore.properties are not in the repository (both are in .gitignore). To sign, either keep a local keystore.properties (storeFile, storePassword, keyAlias, keyPassword) next to build.sh, or set:
export AMBIENT_TV_KEYSTORE_FILE=/path/to/release.jks
export AMBIENT_TV_KEYSTORE_PASSWORD=…
export AMBIENT_TV_KEY_ALIAS=…
export AMBIENT_TV_KEY_PASSWORD=…
Without either, debug builds work and release APKs stay unsigned. ./build.sh gen-keystore creates a new key.

Spotify setup
- Open the Spotify Developer Dashboard, sign in and choose Create app.
- Enter any name and description. Under Which API/SDKs are you planning to use? select Web API.
- Add both Redirect URIs and save:
ambienttv://spotify-auth (sign-in on the device)https://seinist.github.io/ambient-tv-spotify-callback/spotify-callback.html (QR sign-in on a TV; the page only forwards the code to the TV in your network)
- Open the app's Settings and copy the Client ID.
- In Ambient TV: Settings › Media sources & accounts › Spotify → in the Spotify account section paste it into Spotify client ID, then Sign in.
- New apps run in Development mode: under User Management in the dashboard, add the Spotify account(s) (name + email) that should be able to sign in.
Releases
A v* tag push builds the signed release and debug APKs and publishes a GitHub Release — setup, secrets and versioning: build docs §14.5.
Try it & help shape it
Ambient TV is built by one enthusiast for everyone who wants more from their media setup. Give it a spin, push the filters to the limit (gently — see the disclaimer) and tell me what you think: bugs, crashes, ideas and "it would be great if…" are all welcome in the issues. Every report helps make Ambient TV the best media client on Android TV.
Known limits
- NNEDI deinterlace weights (
app/src/main/res/raw/nnedi3_deinterlace_weights.bin, GPLv2) are kept in-tree; other native libraries (MPV/FFmpeg, …) are built or downloaded by ./build.sh on first use.
- No guarantee for every codec/filter combination on every device; image filters need a GPU video output
- Files: no NFS Kerberos, NFSv4.1+ or NetBIOS discovery, no FTP; WebDAV with Basic or Digest auth
- DLNA renderer: no Google Cast, DRM content or images
