2.2 Android

  • For versions 4.4 and 4.4.LTS, add mavenCentral() to your build.gradle and make sure that it is listed before jcenter()
  • For 4.3.2 and older releases, add jcenter()
    repositories {
    mavenCentral()
}

  1. Add MobileFFmpeg dependency to your build.gradle in mobile-ffmpeg-<package name> pattern.

     dependencies {
     implementation 'com.arthenica:mobile-ffmpeg-full:4.4'
 }

  2. 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);
 }

  3. 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));
         }
     }
 });

  4. 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);
 }

  5. 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);
 }

  6. Stop ongoing FFmpeg operations.

    • Stop all executions
        FFmpeg.cancel();
    • Stop a specific execution
        FFmpeg.cancel(executionId);

  7. Get media information for a file.

     MediaInformation info = FFprobe.getMediaInformation("<file path or uri>");

  8. 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>");

  9. Enable log callback.

     Config.enableLogCallback(new LogCallback() {
     public void apply(LogMessage message) {
         Log.d(Config.TAG, message.getText());
     }
 });

  10. 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()));
    }
});

  11. Ignore the handling of a signal.

    Config.ignoreSignal(Signal.SIGXCPU);

  12. 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()));
}

  13. Set default log level.

    Config.setLogLevel(Level.AV_LOG_FATAL);

  14. Register custom fonts directory.

    Config.setFontDirectory(this, "<folder with fonts>", Collections.EMPTY_MAP);

2.3 iOS / tvOS

  1. Add MobileFFmpeg dependency to your Podfile in mobile-ffmpeg-<package name> pattern.

    • iOS

      pod 'mobile-ffmpeg-full', '~> 4.4'

    • tvOS

      pod 'mobile-ffmpeg-tvos-full', '~> 4.4'

  2. Execute synchronous FFmpeg commands.

     #import <mobileffmpeg/MobileFFmpegConfig.h>
 #import <mobileffmpeg/MobileFFmpeg.h>

 int rc = [MobileFFmpeg execute: @"-i file1.mp4 -c:v mpeg4 file2.mp4"];

 if (rc == RETURN_CODE_SUCCESS) {
     NSLog(@"Command execution completed successfully.\n");
 } else if (rc == RETURN_CODE_CANCEL) {
     NSLog(@"Command execution cancelled by user.\n");
 } else {
     NSLog(@"Command execution failed with rc=%d and output=%@.\n", rc, [MobileFFmpegConfig getLastCommandOutput]);
 }

  3. Execute asynchronous FFmpeg commands.

     #import <mobileffmpeg/MobileFFmpegConfig.h>
 #import <mobileffmpeg/MobileFFmpeg.h>

 long executionId = [MobileFFmpeg executeAsync:@"-i file1.mp4 -c:v mpeg4 file2.mp4" withCallback:self];

 - (void)executeCallback:(long)executionId :(int)returnCode {
     if (rc == RETURN_CODE_SUCCESS) {
         NSLog(@"Async command execution completed successfully.\n");
     } else if (rc == RETURN_CODE_CANCEL) {
         NSLog(@"Async command execution cancelled by user.\n");
     } else {
         NSLog(@"Async command execution failed with rc=%d.\n", rc);
     }
 }

  4. Execute FFprobe commands.

     #import <mobileffmpeg/MobileFFmpegConfig.h>
 #import <mobileffmpeg/MobileFFprobe.h>

 int rc = [MobileFFprobe execute: @"-i file1.mp4"];

 if (rc == RETURN_CODE_SUCCESS) {
     NSLog(@"Command execution completed successfully.\n");
 } else if (rc == RETURN_CODE_CANCEL) {
     NSLog(@"Command execution cancelled by user.\n");
 } else {
     NSLog(@"Command execution failed with rc=%d and output=%@.\n", rc, [MobileFFmpegConfig getLastCommandOutput]);
 }

  5. Check execution output later.

     int rc = [MobileFFmpegConfig getLastReturnCode];
 NSString *output = [MobileFFmpegConfig getLastCommandOutput];

 if (rc == RETURN_CODE_SUCCESS) {
     NSLog(@"Command execution completed successfully.\n");
 } else if (rc == RETURN_CODE_CANCEL) {
     NSLog(@"Command execution cancelled by user.\n");
 } else {
     NSLog(@"Command execution failed with rc=%d and output=%@.\n", rc, output);
 }

  6. Stop ongoing FFmpeg operations.

    • Stop all executions

        [MobileFFmpeg cancel];
    • Stop a specific execution
        [MobileFFmpeg cancel:executionId];

  7. Get media information for a file.

     MediaInformation *mediaInformation = [MobileFFprobe getMediaInformation:@"<file path or uri>"];

  8. Record video and audio using iOS camera. This operation is not supported on tvOS since AVFoundation is not available on tvOS.

     [MobileFFmpeg execute: @"-f avfoundation -r 30 -video_size 1280x720 -pixel_format bgr0 -i 0:0 -vcodec h264_videotoolbox -vsync 2 -f h264 -t 00:00:05 %@", recordFilePath];

  9. Enable log callback.

     [MobileFFmpegConfig setLogDelegate:self];

 - (void)logCallback:(long)executionId :(int)level :(NSString*)message {
     dispatch_async(dispatch_get_main_queue(), ^{
         NSLog(@"%@", message);
     });
 }

  10. Enable statistics callback.

    [MobileFFmpegConfig setStatisticsDelegate:self];

- (void)statisticsCallback:(Statistics *)newStatistics {
    dispatch_async(dispatch_get_main_queue(), ^{
        NSLog(@"frame: %d, time: %d\n", newStatistics.getVideoFrameNumber, newStatistics.getTime);
    });
}

  11. Ignore the handling of a signal.

    [MobileFFmpegConfig ignoreSignal:SIGXCPU];

  12. List ongoing executions.

    NSArray* ffmpegExecutions = [MobileFFmpeg listExecutions];
for (int i = 0; i < [ffmpegExecutions count]; i++) {
    FFmpegExecution* execution = [ffmpegExecutions objectAtIndex:i];
    NSLog(@"Execution %d = id: %ld, startTime: %@, command: %@.\n", i, [execution getExecutionId], [execution getStartTime], [execution getCommand]);
}

  13. Set default log level.

    [MobileFFmpegConfig setLogLevel:AV_LOG_FATAL];

  14. Register custom fonts directory.

    [MobileFFmpegConfig setFontDirectory:@"<folder with fonts>" with:nil];
