| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>Existing interop / sharing extensions require support for a minimum set of image formats, however many OpenCL implementations may support sharing image formats above and beyond the minimum. |
| This extension provides a mechanism for an application to query the set of API-specific image formats that an OpenCL implementation can accept for sharing.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Note that the query functionality provided by this extension does not replace API-specific query functions or guarantee that an API-specific image with the returned format may be created. |
| Additionally, some APIs may require that a buffer or image be created with particular flags or parameters to be shared with OpenCL, so this extension does not guarantee that all API-specific images of the queried formats may be shared with OpenCL. |
| It does, however, guarantee that some API-specific images of the queried formats may be shared with OpenCL.</p> |

| <p>What should the name of this extension be?</p> |

| <div class="content"> |
| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code></p> |
| </div> |
| <div class="paragraph"> |
| <p>Discussion: The best name appears to be cl_intel_sharing_format_query. |
| Another possibility is cl_intel_interop_format_query, but it seems better to have 'sharing' in the name, since all of the API-specific sharing extensions also have 'sharing' in the name, with the exception of cl_khr_egl_image.</p> |

| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code></p> |
| </div> |
| <div class="paragraph"> |
| <p>Discussion: Since cl_khr_d3d11_sharing is required by cl_intel_d3d11_nv12_media_sharing, we do not need to say anything about cl_intel_d3d11_nv12_media_sharing in this spec.</p> |

| <p>What should the query for EGL images return?</p> |
| <div class="openblock"> |
| <div class="content"> |
| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code>, this spec will not support EGL sharing format queries.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Discussion: The most common flow to get an EGL image to interop with appears to be:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Create a GraphicBuffer with a requested PIXEL_FORMAT</p> |
| </li> |
| <li> |
| <p>Get an EGLClientBuffer with the getNativeBuffer() member function</p> |
| </li> |
| <li> |
| <p>Create an EGLImageKHR by passing the EGLClientBuffer to eglCreateImageKHR()</p> |
| </li> |
| <li> |
| <p>Create an OpenCL cl_mem from the EGLImageKHR using clCreateFromEGLImageKHR()</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>So, arguably the query for EGL images should return PIXEL_FORMATs that can be passed to the GraphicBuffer constructor to get an image to interop with, which would work with this flow, but not for other flows that could also create EGL images to interop with.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Since there are multiple valid flows that can result in an EGL image to interop with, does it even make sense to have a query for EGL images?</p> |
| </div> |
| <div class="paragraph"> |
| <p>Decision: Not going to support EGL sharing format queries for now, due to the multiple "domains" that can create EGL images. |
| If desired, we can always add cl_intel_egl_sharing_format_query at a later date. |
| Note as well that the EGL sharing extension doesn’t have a "list of supported image formats" like the other sharing APIs, so the value of a sharing format query for EGL is already less than it is for other sharing APIs.</p> |

| <p>What should the query for VA_API media surfaces return?</p> |

| <div class="content"> |
| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code></p> |
| </div> |
| <div class="paragraph"> |
| <p>Discussion: Right now it’s defined to return a VAImageFormat, which is correct, but arguably overkill since we’re only using VA_API sharing for media surfaces. |
| The alternative is to return unsigned ints representing the appropriate fourcc codes.</p> |
| </div> |
| </div> |
| </div> |
| </li> |
| <li> |
| <p>For OpenGL sharing, should the query include the un-sized, un-typed "base" internal formats? Or should it only include the sized internal formats?</p> |
| <div class="openblock"> |
| <div class="content"> |
| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code></p> |
| </div> |
| <div class="paragraph"> |
| <p>Discussion: For the base internal formats, the user is at the mercy of the actual internal format chosen by the OpenGL driver. |
| So, it may be possible that there could be OpenGL textures created with the same base internal format, where one of them is shareable with OpenCL and one of them is not, which could be confusing. |
| Then again, it’s also somewhat confusing to leave the base internal formats out of the image format query since it’s likely that sharing will succeed for OpenGL textures created with base the base internal formats in many cases.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Decision: This extension won’t say anything about whether the query will return of the un-sized, un-typed "base" internal formats or the sized internal formats.</p> |

| <p>How should we handle sharing APIs like DX9 media sharing where a format may be supported for sharing for some planes (such as the individual planes of a planar YUV image) but not for other planes (such as a plane value indicating a monolithic planar YUV image)?</p> |
| <div class="openblock"> |
| <div class="content"> |
| <div class="paragraph"> |
| <p>Status: <code>RESOLVED</code></p> |
| </div> |
| <div class="paragraph"> |
| <p>Decision: Added a "plane" argument to the sharing format query for the following APIs:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>clGetSupportedDX9MediaSurfaceFormatsINTEL</p> |

| <p>Note that the D3D10 / D3D11 sharing APIs specify the "plane" using the "subresource" argument, but for the purposes of the sharing format query we really do want this to be the "plane", since it doesn’t make sense to query for a particular "subresource".</p> |
