I am using php to create a video with fade effects. But exec() function gives following output:

Why it is giving unrecognized option 'vf' while it works fine when run directly on server.My command is : "ffmpeg -i /usr/slideshow/frame1.mp4 -vf 'fade=out:0:5' /usr/slideshow/fade1.mp4"

I am executing it with exec() function. Why the error is coming and what should i use to apply filter to my input video. I am working on CentOS server.

Please guide me...

I found the answer i just tried the full path of ffmpeg directory where ffmpeg was installed and it worked...
