+/**
+ * GST_CAPS_FEATURE_MEMORY_DMABUF:
+ *
+ * Constant that defines the caps feature name for DMA buffer sharing.
+ *
+ * It has to be used for non-mappable dma-buf only, i.e. when the underlying
+ * memory is not mappable to user space. Or when the mapped memory contains
+ * non meaningful data. It can be the case for protected content or when the
+ * user wants explicitly avoid any software post processing.
+ *
+ * In these cases all elements between the exported and the importer has to work
+ * in passthrough mode. This is done by adding this caps feature.
+ *
+ * When the memory is mappable for read and write requests then it is assumes
+ * to be a fast path and so this caps feature should not be used. Though
+ * according to the dma-buf protocal, while it is mapped it prevents the
+ * exporter to migrate the buffer.
+ *
+ * This caps feature should not serve at all the purpose of selecting the
+ * @GST_ALLOCATOR_DMABUF allocator during caps negotiation.
+ * When the exporter is the upstream element from the importer point of view,
+ * the exporter should try to map the dma buffer at runtime (preferrably during
+ * decide_allocation phase). When it succeeds for #GST_MAP_READWRITE this caps
+ * feature should not be used. This allows scalers, color converts and any image
+ * processing filters to work directly on the dma buffer.
+ * In this case the importer element should check all incomming memory using
+ * gst_is_dmabuf_memory().
+ *
+ * Since: 1.11
