+Subject: [PATCH 19/31] videocrop: send a query by the first invorker of
+ query_stride_supported
+
+The query_stride_supported() might be failed because start() method
+can be called before the pipeline is constructed. To resolve this issue,
+this patch has the first invoker of query_stride_supported() send
+the query to downstream plugins. The result of query is cached
+at the first invoking.
