+Subject: [PATCH 06/31] videocrop: send a query whether the rowstride
+ capability is supported
+
+This patch sends a query which asks downstream plugins whether
+can handle the rowstride capability.
+gst_video_crop_start() can be invoked when the pad is enabled.
+The query is issued by gst_video_crop_start() once at initialization.
+
+This patch is preliminary for the zero-copy cropping.
