Add MobileFFmpeg dependency to your
Podfile
inmobile-ffmpeg-tvos-<package name>
pattern.pod 'mobile-ffmpeg-tvos-full', '~> 4.4'
-
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]); }
-
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); } }
-
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]); }
-
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); }
-
Stop ongoing FFmpeg operations.
- Stop all executions
[MobileFFmpeg cancel];
- Stop a specific execution
[MobileFFmpeg cancel:executionId];
- Stop all executions
-
Get media information for a file.
MediaInformation *mediaInformation = [MobileFFprobe getMediaInformation:@"<file path or uri>"];
-
Enable log callback.
[MobileFFmpegConfig setLogDelegate:self]; - (void)logCallback:(long)executionId :(int)level :(NSString*)message { dispatch_async(dispatch_get_main_queue(), ^{ NSLog(@"%@", message); }); }
-
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); }); }
-
Ignore the handling of a signal.
[MobileFFmpegConfig ignoreSignal:SIGXCPU];
-
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]); }
-
Set default log level.
[MobileFFmpegConfig setLogLevel:AV_LOG_FATAL];
-
Register custom fonts directory.
[MobileFFmpegConfig setFontDirectory:@"<folder with fonts>" with:nil];
