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

3. Check execution output.

   int rc = [MobileFFmpeg getLastReturnCode];
   NSString *output = [MobileFFmpeg 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);
   }
   

4. Stop an ongoing operation.

   [MobileFFmpeg cancel];
   

5. Get media information for a file.

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

7. List enabled external libraries.

   NASArray *externalLibraries = [MobileFFmpegConfig getExternalLibraries];
   

8. Enable log callback.

   - (void)logCallback: (int)level :(NSString*)message {
       dispatch_async(dispatch_get_main_queue(), ^{
           NSLog(@"%@", message);
       });
   }
   ...
   [MobileFFmpegConfig setLogDelegate:self];
   

9. Enable statistics callback.

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