What it is

OpenPlayer is an open-source Android video player with no ads and no tracking. It aims to offer, as free software, the useful features of popular closed-source players: screen gestures, subtitle management, decoder choice, network sources and more. Everything is written from scratch; no code, name, logo or design asset of any closed-source player is used.

The app is available in 12 languages (English, Türkçe, Español, Français, Italiano, Deutsch, Português, 简体中文, 日本語, 한국어, Русский, العربية). Translations are machine-made and have not been reviewed by native speakers; corrections are welcome.

Download

Get OpenPlayer.apk from the Releases page and install it (Android 7.0+). You may need to allow installing from unknown sources.

Only download from the Releases page. The signing key is public (open source), so an APK from anywhere else could be a tampered copy that installs over the real app.

Status: beta. Built and tested on CI and an emulator, but not yet extensively tested on real devices. Report problems in Issues.

Features

Playback

• Subtitle gestures: horizontal swipe for previous / next line, vertical swipe for position, pinch for size
• Online subtitle search (OpenSubtitles.com). You need to enter your own API key under Settings → Subtitles
• Subtitle translation: translate a loaded subtitle file into another language and save it as a new .srt. Providers: MyMemory (no account), LibreTranslate-compatible address, OpenAI-compatible AI address (Groq, OpenRouter, Gemini, Ollama… with your own key)

Files

• Lists only folders that contain videos; thumbnails, duration, "new" and "watched" markers, sorting, grid / list views

Known limitations

• No full ASS/SSA rendering (libass): styles, colors and position work, but animations, advanced effects, drawing commands and embedded fonts do not.
• Image-based subtitles (VobSub, PGS) and Teletext are not drawn.
• Sidecar subtitles are not found automatically for network videos; add them manually from the player.
• No Chromecast, no deinterlacing, no decoder plugins.
• SMB share lists cannot be enumerated; type the share name.

Building

No Android Studio needed: every push is built by GitHub Actions and the APK can be downloaded from the Actions tab. Locally: JDK 17, Android SDK and gradle assembleDebug (Gradle 8.14+).

Privacy and security

• No ads, tracking or analytics. The app only connects to addresses you open, subtitle search and the servers you configure.
• Network-server and OpenSubtitles passwords are stored unencrypted in the app's private storage.
• app/openplayer-test.jks is a public test signing key, used so that releases can update over each other. Use your own key for store releases.
• See SECURITY.md for details and how to report a vulnerability.
