I need to execute a shell script. The catch is I want to do this

$Command = "nohup cvlc input --sout '#transcode {vcodec=h264,acodec=mp3,samplerate=44100}:std{access=http,mux=ffmpeg{mux=flv},dst=0.0.0.0:8083/".output"}' &";
$str = shell_exec($Command);

I dont want it to wait till the command is finished, i want it to run in a background process.
I do not want another php thread as it will timeout the command can take up to 3 hours to finish.

    $str = shell_exec($Command.' 2>&1 > out.log');

    You need to redirect the output of the command.

    If a program is started with this function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
