FFmpegKit for Android

1. Features

Supports API Level 24+ on Main releases and API Level 16+ on LTS releases
Includes arm-v7a, arm-v7a-neon, arm64-v8a, x86 and x86_64 architectures
Can handle Storage Access Framework (SAF) Uris
Camera access on supported devices
Builds shared native libraries (.so)
Creates Android archive with .aar extension

2. Building

Run android.sh at project root directory to build ffmpeg-kit and ffmpeg shared libraries.

Please note that FFmpegKit project repository includes the source code of FFmpegKit only. android.sh needs network connectivity and internet access to github.com in order to download the source code of FFmpeg and external libraries enabled.

2.1 Prerequisites

android.sh requires the following tools and packages.

2.1.1 Android Tools

Android SDK Build Tools
Android NDK r22b or later with LLDB and CMake (See #292 if you want to use NDK r23b or later)

2.1.2 Packages

Use your package manager (apt, yum, dnf, brew, etc.) to install the following packages.

autoconf automake libtool pkg-config curl git doxygen nasm cmake gcc gperf texinfo yasm bison autogen wget autopoint meson ninja ragel groff gtk-doc-tools libtasn1

2.1.3 Environment Variables

Set ANDROID_SDK_ROOT and ANDROID_NDK_ROOT environment variables before running android.sh.

export ANDROID_SDK_ROOT=<Android SDK Path>
export ANDROID_NDK_ROOT=<Android NDK Path>

2.2 Options

Use --enable-<library name> flag to support additional external or system libraries and --disable-<architecture name> to disable architectures you don't want to build.

./android.sh --enable-fontconfig --disable-arm-v7a-neon

Run --help to see all available build options.

2.3 LTS Binaries

Use --lts option to build lts binaries for each architecture.

2.4 Build Output

All libraries created by android.sh can be found under the prebuilt directory.

Android archive (.aar file) for Main builds is located under the bundle-android-aar folder.
Android archive (.aar file) for LTS builds is located under the bundle-android-aar-lts folder.

3. Using

3.1 Android API

Declare mavenCentral repository and add FFmpegKit dependency to your build.gradle in ffmpeg-kit-<package name> pattern. Use one of the FFmpegKit package names given in the project README.
```
repositories {
    mavenCentral()
}

dependencies {
    implementation 'com.arthenica:ffmpeg-kit-full:6.0-2'
}
```

Execute synchronous FFmpeg commands.

import com.arthenica.ffmpegkit.FFmpegKit;

FFmpegSession session = FFmpegKit.execute("-i file1.mp4 -c:v mpeg4 file2.mp4");
if (ReturnCode.isSuccess(session.getReturnCode())) {

    // SUCCESS

} else if (ReturnCode.isCancel(session.getReturnCode())) {

    // CANCEL

} else {

    // FAILURE
    Log.d(TAG, String.format("Command failed with state %s and rc %s.%s", session.getState(), session.getReturnCode(), session.getFailStackTrace()));

}

Each execute call (sync or async) creates a new session. Access every detail about your execution from the session created.

FFmpegSession session = FFmpegKit.execute("-i file1.mp4 -c:v mpeg4 file2.mp4");

// Unique session id created for this execution
long sessionId = session.getSessionId();

// Command arguments as a single string
String command = session.getCommand();

// Command arguments
String[] arguments = session.getArguments();

// State of the execution. Shows whether it is still running or completed
SessionState state = session.getState();

// Return code for completed sessions. Will be null if session is still running or ends with a failure
ReturnCode returnCode = session.getReturnCode();

Date startTime = session.getStartTime();
Date endTime = session.getEndTime();
long duration = session.getDuration();

// Console output generated for this execution
String output = session.getOutput();

// The stack trace if FFmpegKit fails to run a command
String failStackTrace = session.getFailStackTrace();

// The list of logs generated for this execution
List<com.arthenica.ffmpegkit.Log> logs = session.getLogs();

// The list of statistics generated for this execution
List<Statistics> statistics = session.getStatistics();

Execute asynchronous FFmpeg commands by providing session specific execute/log/session callbacks.

FFmpegKit.executeAsync("-i file1.mp4 -c:v mpeg4 file2.mp4", new FFmpegSessionCompleteCallback() {

    @Override
    public void apply(FFmpegSession session) {
        SessionState state = session.getState();
        ReturnCode returnCode = session.getReturnCode();

        // CALLED WHEN SESSION IS EXECUTED

        Log.d(TAG, String.format("FFmpeg process exited with state %s and rc %s.%s", state, returnCode, session.getFailStackTrace()));
    }
}, new LogCallback() {

    @Override
    public void apply(com.arthenica.ffmpegkit.Log log) {

        // CALLED WHEN SESSION PRINTS LOGS

    }
}, new StatisticsCallback() {

    @Override
    public void apply(Statistics statistics) {

        // CALLED WHEN SESSION GENERATES STATISTICS

    }
});

Execute FFprobe commands.

Synchronous

FFprobeSession session = FFprobeKit.execute(ffprobeCommand);

if (!ReturnCode.isSuccess(session.getReturnCode())) {
    Log.d(TAG, "Command failed. Please check output for the details.");
}

Asynchronous

FFprobeKit.executeAsync(ffprobeCommand, new FFprobeSessionCompleteCallback() {

    @Override
    public void apply(FFprobeSession session) {

        CALLED WHEN SESSION IS EXECUTED

    }
});

Get media information for a file.

MediaInformationSession mediaInformation = FFprobeKit.getMediaInformation("<file path or uri>");
mediaInformation.getMediaInformation();

Stop ongoing FFmpeg operations.
- Stop all executions
```
FFmpegKit.cancel();
```
- Stop a specific session
```
FFmpegKit.cancel(sessionId);
```

Convert Storage Access Framework (SAF) Uris into paths that can be read or written by FFmpegKit.

Reading a file:

Uri safUri = intent.getData();
String inputVideoPath = FFmpegKitConfig.getSafParameterForRead(requireContext(), safUri);
FFmpegKit.execute("-i " + inputVideoPath + " -c:v mpeg4 file2.mp4");

Writing to a file:

Uri safUri = intent.getData();
String outputVideoPath = FFmpegKitConfig.getSafParameterForWrite(requireContext(), safUri);
FFmpegKit.execute("-i file1.mp4 -c:v mpeg4 " + outputVideoPath);

Writing to a file in a custom mode.

Uri safUri = intent.getData();
String path = FFmpegKitConfig.getSafParameter(requireContext(), safUri, "rw");
FFmpegKit.execute("-i file1.mp4 -c:v mpeg4 " + path);

Get previous FFmpeg and FFprobe sessions from session history.

List<Session> sessions = FFmpegKitConfig.getSessions();
for (int i = 0; i < sessions.size(); i++) {
    Session session = sessions.get(i);
    Log.d(TAG, String.format("Session %d = id:%d, startTime:%s, duration:%s, state:%s, returnCode:%s.",
          i,
          session.getSessionId(),
          session.getStartTime(),
          session.getDuration(),
          session.getState(),
          session.getReturnCode()));
}

Enable global callbacks.

Session type specific Complete Callbacks, called when an async session has been completed

FFmpegKitConfig.enableFFmpegSessionCompleteCallback(new FFmpegSessionCompleteCallback() {

    @Override
    public void apply(FFmpegSession session) {

    }
});

FFmpegKitConfig.enableFFprobeSessionCompleteCallback(new FFprobeSessionCompleteCallback() {

    @Override
    public void apply(FFprobeSession session) {

    }
});

FFmpegKitConfig.enableMediaInformationSessionCompleteCallback(new MediaInformationSessionCompleteCallback() {

    @Override
    public void apply(MediaInformationSession session) {

    }
});

Log Callback, called when a session generates logs

FFmpegKitConfig.enableLogCallback(new LogCallback() {

    @Override
    public void apply(final com.arthenica.ffmpegkit.Log log) {
        ...
    }
});

Statistics Callback, called when a session generates statistics

FFmpegKitConfig.enableStatisticsCallback(new StatisticsCallback() {

    @Override
    public void apply(final Statistics newStatistics) {
        ...
    }
});

Ignore the handling of a signal. Required by Mono and frameworks that use Mono, e.g. Unity and Xamarin.
```
FFmpegKitConfig.ignoreSignal(Signal.SIGXCPU);
```

Register system fonts and custom font directories.

FFmpegKitConfig.setFontDirectoryList(context, Arrays.asList("/system/fonts", "<folder with fonts>"), Collections.EMPTY_MAP);
