iOS

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

   pod 'mobile-ffmpeg-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 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]);
   }
   

4. 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);
   }
   

5. Stop an ongoing FFmpeg operation.

   [MobileFFmpeg cancel];
   

6. Get media information for a file.

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

7. Record video and audio using iOS camera.

   [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];
   

8. List enabled external libraries.

   NSArray *externalLibraries = [MobileFFmpegConfig getExternalLibraries];
   

9. Enable log callback.

   [MobileFFmpegConfig setLogDelegate:self];
   
   - (void)logCallback: (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. Set log level.

    [MobileFFmpegConfig setLogLevel:AV_LOG_FATAL];
    

12. Register custom fonts directory.

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