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

   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. Enable log callback.

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

9. 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);
       });
   }
   

10. Ignore the handling of a signal.

    [MobileFFmpegConfig ignoreSignal:SIGXCPU];
    

11. 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]);
    }
    

12. Set default log level.

    [MobileFFmpegConfig setLogLevel:AV_LOG_FATAL];
    

13. Register custom fonts directory.

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