            Bug ID: 746087
           Summary: GstVideoCropMeta implementation is inconsistent
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: Linux

     GNOME version: ---

Currently GstVideoCropMeta implementation is problematic - caps width/height
values and GstVideoMeta settings are a bit jumbled, and things need fixing and
documenting across the board.

>From slomo in bug #74010, it should work like this:

- CAPS event contains the display width/height (otherwise applications will
become unhappy, GstDiscoverer reports wrong information, etc)
- caps inside the ALLOCATION query contain the memory width/height
- GstVideoMeta contains the memory width/height
- GstVideoCropMeta contains how much should be cropped relative to the values
inside the video meta and the ALLOCATION query caps
