shell_exec() is not working for specific command
I have installed CALIBRE . Calibre convert files from pdf to epub. in terminal when i run /opt/calibre/ebook-convert it started and working perfectly.
but when i run same command in my shell_exec() it is not working. But other command in shell_exec is working and running fine.

To troubleshoot this I would store the command in a variable
Something like
$command = 'ffmpeg -loglevel quiet -stats -i ' . $filename . ' -vf scale=1280:720 ' -o . $filename . '-720p.' . $extension;
echo command;
Then I would copy paste it and try running it.
It most likely has to do with whitespace in the file name. Try replacing ' ' with '\ '.
