<doc xml:space="preserve">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 protocol, 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 (preferably 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 incoming memory using
|
|
gst_is_dmabuf_memory().</doc>
