           line="29">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().</doc>
