<p>General information about sharing memory objects with DX9 follows.</p>
</div>
<div class="paragraph">
<p>The goal of this extension is to allow applications to use media surfaces as
OpenCL memory objects. This allows efficient sharing of data between OpenCL
and selected adapter APIs (only DX9 for now). If this extension is
supported, an OpenCL image object can be created from a media surface and
the OpenCL API can be used to execute kernels that read and/or write memory
objects that are media surfaces. Note that OpenCL memory objects may be
created from the adapter media surface if and only if the OpenCL context has
been created from that adapter.</p>
</div>
<div class="paragraph">
<p>If this extension is supported by an implementation, the string
"cl_khr_dx9_media_sharing" will be present in the <code>CL_PLATFORM_EXTENSIONS</code>
(see <a href="clGetPlatformInfo.html">clGetPlatformInfo</a>) or <code>CL_DEVICE_EXTENSIONS</code> (see
<a href="clGetDeviceInfo.html">clGetDeviceInfo</a>).</p>

<p>As currently proposed the interfaces for this extension would be provided in

<div class="title">Surface formats for Media Surface Sharing</div>
<p>This section includes the D3D surface formats that are supported when the
adapter type is one of the Direct 3D lineage. Using a D3D surface format not
listed here is an error. To extend the use of this extension to support
media adapters beyond DirectX9 tables similar to the ones in this section
will need to be defined for the surface formats supported by the new media
adapter. All implementations that support this extension are required to
support the NV12 surface format, the other surface formats supported are the
same surface formats that the adapter you are sharing with supports as long
as they are listed in the tables below (Tables 9.10.3 and 9.10.4).</p>
