From below command:

ffmpeg -i /var/bigbluebutton/published/presentation/f593599f005cc1ed453c0e92c37236063e6144b0-1480310327986/audio/audio.ogg  2>&1 | grep Duration | cut -d ' ' -f 4 | sed s/,//"

Output is:

00:07:10:00

When I Put this command in php

echo shell_exec("ffmpeg -i /var/bigbluebutton/published/presentation/f593599f005cc1ed453c0e92c37236063e6144b0-1480310327986/audio/audio.ogg  2>&1 | grep Duration | cut -d ' ' -f 4 | sed s/,//",$result);

It doesn't give any output.
