capsfilter

The element does not modify data as such, but can enforce limitations on the data format.

Example launch line

 gst-launch-1.0 videotestsrc ! capsfilter caps=video/x-raw,format=GRAY8 ! videoconvert ! autovideosink

Limits acceptable video from videotestsrc to be grayscale. Equivalent to

 gst-launch-1.0 videotestsrc ! video/x-raw,format=GRAY8 ! videoconvert ! autovideosink

which is a short notation for the capsfilter element.
