How to integrate FFmpeg library in Android studio to make Android FFmpeg video editing application
Follow these steps to integrate ffmpeg library in Android
Android version requirement
- For versions 4.4 and 4.4.LTS, add mavenCentral() to your build.gradle and make sure that it is listed before jcenter()
- For
4.3.2and older releases, addjcenter()
repositories {
mavenCentral()
}
- Add MobileFFmpeg dependency to your
build.gradleinmobile-ffmpeg-<package name>pattern
dependencies {
implementation 'com.arthenica:mobile-ffmpeg-full:4.4'
}
Execute synchronous FFmpeg commands
import com.arthenica.mobileffmpeg.Config;
import com.arthenica.mobileffmpeg.FFmpeg;
int rc = FFmpeg.execute("-i file1.mp4 -c:v mpeg4 file2.mp4");
if (rc == RETURN_CODE_SUCCESS) {
Log.i(Config.TAG, "Command execution completed successfully.");
} else if (rc == RETURN_CODE_CANCEL) {
Log.i(Config.TAG, "Command execution cancelled by user.");
} else {
Log.i(Config.TAG, String.format("Command execution failed with rc=%d and the output below.", rc));
Config.printLastCommandOutput(Log.INFO);
}
Execute asynchronous FFmpeg commands
import com.arthenica.mobileffmpeg.Config;
import com.arthenica.mobileffmpeg.FFmpeg;
long executionId = FFmpeg.executeAsync("-i file1.mp4 -c:v mpeg4 file2.mp4", new ExecuteCallback() {
@Override
public void apply(final long executionId, final int returnCode) {
if (returnCode == RETURN_CODE_SUCCESS) {
Log.i(Config.TAG, "Async command execution completed successfully.");
} else if (returnCode == RETURN_CODE_CANCEL) {
Log.i(Config.TAG, "Async command execution cancelled by user.");
} else {
Log.i(Config.TAG, String.format("Async command execution failed with returnCode=%d.", returnCode));
}
}
});
Execute FFprobe commands
import com.arthenica.mobileffmpeg.Config;
import com.arthenica.mobileffmpeg.FFprobe;
int rc = FFprobe.execute("-i file1.mp4");
if (rc == RETURN_CODE_SUCCESS) {
Log.i(Config.TAG, "Command execution completed successfully.");
} else {
Log.i(Config.TAG, String.format("Command execution failed with rc=%d and the output below.", rc));
Config.printLastCommandOutput(Log.INFO);
}
Check execution output later
int rc = Config.getLastReturnCode();
if (rc == RETURN_CODE_SUCCESS) {
Log.i(Config.TAG, "Command execution completed successfully.");
} else if (rc == RETURN_CODE_CANCEL) {
Log.i(Config.TAG, "Command execution cancelled by user.");
} else {
Log.i(Config.TAG, String.format("Command execution failed with rc=%d and the output below.", rc));
Config.printLastCommandOutput(Log.INFO);
}
Stop ongoing FFmpeg operations
- Stop all executions
FFmpeg.cancel();
- Stop a specific execution
FFmpeg.cancel(executionId);
Get media information for a file
MediaInformation info = FFprobe.getMediaInformation("<file path or uri>");
Record video using Android camera
FFmpeg.execute("-f android_camera -i 0:0 -r 30 -pixel_format bgr0 -t 00:00:05 <record file path>");
Enable log callback
Config.enableLogCallback(new LogCallback() {
public void apply(LogMessage message) {
Log.d(Config.TAG, message.getText());
}
});
Enable statistics callback
Config.enableStatisticsCallback(new StatisticsCallback() {
public void apply(Statistics newStatistics) {
Log.d(Config.TAG, String.format("frame: %d, time: %d", newStatistics.getVideoFrameNumber(), newStatistics.getTime()));
}
});
Ignore the handling of a signal
Config.ignoreSignal(Signal.SIGXCPU);
List ongoing executions
final List<FFmpegExecution> ffmpegExecutions = FFmpeg.listExecutions();
for (int i = 0; i < ffmpegExecutions.size(); i++) {
FFmpegExecution execution = ffmpegExecutions.get(i);
Log.d(TAG, String.format("Execution %d = id:%d, startTime:%s, command:%s.", i, execution.getExecutionId(), execution.getStartTime(), execution.getCommand()));
}
Set default log level
Config.setLogLevel(Level.AV_LOG_FATAL);
Register custom fonts directory
Config.setFontDirectory(this, "<folder with fonts>", Collections.EMPTY_MAP);
