No register commands for conversion

[William_Cooper]

when i use this code:

    CommandLineExecutorComponent commandLineExecutorComponent = new CommandLineExecutorComponent();
	for (String command : commandLineExecutorComponent.getRegistredCommands()) {
		System.out.println(command);
	}
	
	for (String command : commandLineExecutorComponent.getAvailableCommands()) {
		System.out.println(command);
	}

it doesnt print anything. i cant proceed because when i use ffmpeg its says

Exception in thread "main" org.nuxeo.ecm.platform.commandline.executor.api.CommandNotAvailable: ffmpeg is not a registered command. null
at org.nuxeo.ecm.platform.commandline.executor.service.CommandLineExecutorComponent.execCommand(CommandLineExecutorComponent.java:155)
at tv.migo.nuxeo.IntermidiateTranscoding.run(IntermidiateTranscoding.java:69)
at tv.migo.nuxeo.IntermidiateTranscoding.main(IntermidiateTranscoding.java:78)

code here:

@OperationMethod
public BlobHolder run(BlobHolder blobHolder) throws ClientException, CommandNotAvailable {

	System.out.println(blobHolder.getFilePath());
	System.out.println(blobHolder.getBlob().getFilename());
	System.out.println(blobHolder.getBlob().getLength());
	
	/*
	ConversionServiceImpl conversionServiceImpl = new ConversionServiceImpl();
	BlobHolder holder = conversionServiceImpl.convertToMimeType(".mp4", blobHolder, null);
	*/
	
	CommandLineExecutorComponent commandLineExecutorComponent = new CommandLineExecutorComponent();
	for (String command : commandLineExecutorComponent.getRegistredCommands()) {
		System.out.println(command);
	}
	
	for (String command : commandLineExecutorComponent.getAvailableCommands()) {
		System.out.println(command);
	}
	CmdParameters parameters = new CmdParameters();
	
	parameters.addNamedParameter("-i", blobHolder.getFilePath());
	parameters.addNamedParameter("-vcodec", "dnxhd");
	parameters.addNamedParameter("-b", "115M");
	
	BlobHolder holder = (BlobHolder) commandLineExecutorComponent.execCommand("ffmpeg", parameters);
	
	return holder;
}

Hello,

[William_Cooper]

yes.ffmpeg is found on my own pc and in our nuxeo server. i've tried it.the problem is that NO COMMANDS are available.0.even echo doesn't appear
