Commons Exec not producing the same result as the command line

[Daniel Wamara]

Good evening all, 

I am trying to call ffmpeg via the command exec in order to transcode some 
files and the strange thing happening is that the files produced are not the 
same as the one I can create when calling the same command via the command line.

This is how I am calling fmpeg and I get a file with a particular codec in it 
(strangely not the right one) although launching in the command line exactly 
what I have in the sb.toString() which is the command to be executed, the file 
created has a correct codec. So to say, the same command started via Exec and 
the one started via the command line have not the same result. Anyone has an 
idea?

Thanks.

StringBuilder sb = new StringBuilder("/home/ect/scripts/transcoding.sh ");

sb.append(" " + source.getAbsolutePath());

sb.append(" " + attributes.getCodec());

sb.append(" " + String.valueOf(attributes.getSamplingRate().intValue()));

sb.append(" " + target.getAbsolutePath());


logDebug("command --> " + sb.toString());


CommandLine commandLine = CommandLine.parse(sb.toString());

DefaultExecutor executor = new DefaultExecutor();

executor.execute(commandLine);
