Overview

FFmpegMediaMetadataRetriever is a reimplementation of Android's MediaMetadataRetriever class. The FFmpegMediaMetadataRetriever class provides a unified interface for retrieving frame and meta data from an input media file and uses FFmpeg as its backend.

Key Features:

• Built using FFmpeg version 7.1.1
• ARMv7, x86, x86_64, and ARM_64 support (Note: ARM and MIPS aren't supported as of version 1.0.14)
• Support for API 21+ and 16 KB page sizes
• URL support (Unlike MediaMetadataRetriever, see: http://code.google.com/p/android/issues/detail?id=35794)

Supported protocols:

• file, http, https, mms, mmsh, and rtmp

Supported formats (audio and video):

• aac, acc+, avi, flac, mp2, mp3, mp4, ogg, 3gp and more!

Additional support for:

• ICY Metadata (SHOUTcast metadata)

Using FMMR in your application (Android Studio)

Add the following Maven dependency to your project's build.gradle file:

dependencies {
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-core:1.0.23'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native:1.0.23'
}

Optionally, to support individual ABIs:

dependencies {
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-core:1.0.23'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native-armeabi-v7a:1.0.23'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native-x86:1.0.23'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native-x86_64:1.0.23'
    implementation 'com.github.wseemann:FFmpegMediaMetadataRetriever-native-arm64-v8a:1.0.23'
}

Or, if your application supports individual architectures, extract the appropriate AAR file into you projects "libs" folder:

Prebuilt AARs

Demo Application

A sample application that makes use of FFmpegMediaMetadataRetriever can be downloaded here. Note: The sample application is compiled with support for ALL available formats. This results in a larger library and APK. FFmpeg can be recompiled with a subset of codecs enabled for those wanting a smaller size.

Requirements

• Android Studio Narwhal 2025.1.2 or higher
• Android NDK r27 or higher

Android Studio (Gradle)

Note: The build instructions and scripts assume you are running Unix or Linux. Building on other operating systems is currently not supported.

Execute the following in the root project directory (assuming /path/to/android_sdk/tools is in your PATH):

android update project --path .

Open the newly created local.properties file and add the following lines:

sdk.dir=<path to SDK>
ndk.dir=<path to NDK>

where is the path to your Android SDK, for example:

sdk.dir=/Users/wseemann/Library/Android/sdk

where is the path to your Android NDK, for example:

ndk.dir=/Users/wseemann/Library/Android/sdk/ndk/27.1.12297006

To compile the library in Android Studio, highlight core in the project explorer and run Build->Make Module 'core'. This will also build the native FFmpeg binaries.

Usage

Sample code:

FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();
mmr.setDataSource(mUri);
mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_ALBUM);
mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_ARTIST);
Bitmap b = mmr.getFrameAtTime(2000000, FFmpegMediaMetadataRetriever.OPTION_CLOSEST); // frame at 2 seconds
byte [] artwork = mmr.getEmbeddedPicture();

mmr.release();
