aspectratiocrop
This element crops video frames to a specified aspect-ratio.
If the aspect-ratio is already correct, the element will operate in pass-through mode.
Example launch line
gst-launch-1.0 -v videotestsrc ! video/x-raw,height=640,width=480 ! aspectratiocrop aspect-ratio=16/9 ! ximagesink
This pipeline generates a videostream in 4/3 and crops it to 16/9.
