What it is

ExoPlayer is a deprecated Android media player library that provided extensible video and audio playback with support for multiple formats, codecs (including AV1 via libgav1), and streaming protocols. It enabled developers to build custom media experiences beyond Android's native MediaPlayer, with modularity through extensions like Cast integration and Cronet-based networking. This repository is now archived in favor of AndroidX Media3. Monorepo structure: extensions/ subdirectories contain modular codec/transport plugins (av1, cast, cronet, etc.), each with its own build.gradle, JNI bindings for native codecs (av1/src/main/jni contains CMakeLists.txt and C++ code), and Java facades…

Start here

Open these first:

• README.md — Declares the repository deprecated as of 2024-04-03 with migration path to androidx/media; all contributors must understand…
• build.gradle — Root build configuration using Gradle 7.2.2 and Android toolchain; essential for understanding how all modules compile and…
• extensions/av1/src/main/java/com/google/android/exoplayer2/ext/av1/Libgav1VideoRenderer.j… — Video rendering abstraction for AV1 codec support; demonstrates the core extension pattern used throughout this codebase.
• extensions/cast/src/main/java/com/google/android/exoplayer2/ext/cast/CastPlayer.java — Cast integration entry point; shows how ExoPlayer abstracts remote playback across different device types.
• extensions/cronet/src/main/java/com/google/android/exoplayer2/ext/cronet/CronetDataSource… — HTTP data source using Chromium's Cronet; represents the network I/O abstraction layer for media streaming.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/google/ExoPlayer.git. Install: verify build.gradle lists Gradle 7.2.2 and Kotlin 1.8.20 as buildscript dependencies; ensure Android SDK and Java JDK 8+ are installed. Build: `./gr…

Daily commands:

Build specific modules: ./gradlew :extensions:av1:build (for AV1 decoder extension), ./gradlew :extensions:cast:build (for Cast support), or ./gradlew build for all. No built-in dev server; ExoPlayer is a library,…

…shortened for this brief.

Key cautions & unknowns

• Slowing — last commit 9mo ago
• No CI workflows detected
• Scorecard: default branch unprotected (0/10)
• No active development: PRs and issues will not be reviewed or merged. Deprecated dependencies: Gradle 7.2.2 and Kotlin 1.8.20 are aging; new Android SDK versions may have compatibility issues. **JNI platform…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
