将.mov转换为.mp4 php的问题

Question

I am trying to convert a video with extension .mov to .mp4 format. Following is the command that I try to use

$file_name = "abc.mov";

$mp4_file  = "abc.mp4";

$cmd = 'sudo /usr/bin/ffmpeg -i /path_to_file' . $file_name . ' -strict experimental -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -preset slower -crf 18 -vf "scale=trunc(in_w/2)*2:trunc(in_h/2)*2" /destination_path/' . $mp4_file;
exec($cmd, $out, $res);

However the desired file( with .mp4 ) is not getting created. When I copy the command and paste it inside terminal, the file with the desired format is getting created. However same is not working with exec command in my php code.

I am not able to figure out the actual cause of issue, since it seems out to be strange. Any help shall be appreciated. Thanks in advance
