Passing options to ffprobe

Question

I'm having problem with the ffprobe syntax, getting print format to output default with no keys. There is a nokey option, so I pass in something like this

ffprobe -print_format default nokey

but I get nothing back, not even an error. Is there something wrong with my syntax?

Answer 1

The answer is

-printformat default=nokey=1

Multiple options can be passed in

-print_format default=nokey=1:noprint_wrappers=1

Answer 2

correct syntext wold be

ffprobe -print_format default -skip_frame nokey -i

skip_frame = tells what kind of frame can be skipped to make the ffprobe faster. "nokey" means skip non-key frames (P,B).

but nokey is the default option, and you can "skip" (no pun intended :D ) this option.
