I am newbie to ffmpeg. I am trying to extract the I/B/P frames from a video
file. I went through the documentation and found the following command:

ffmpeg -i input -vf "select=eq(pict_type,PICT_TYPE_I)" output

But, I am getting error for unrecognized option '-vf' as below:

./ffmpeg: unrecognized option '-vf'


Is there any problem with the command or do I need to install anything else?

Thanks & Regards,
