817544860d d3d11: Add support for BGRx and RGBx formats
For such formats, we can re-use existing BGRA/RGBA implementations
but ignoring alpha channel

061e32b197 Add @ prefix to enum-variant references in documentation
Found while working on GStreamer-rs documentation, some enums had this
bit of text pasted verbatim in the enum documentation rather than
attached to the enum-variant.  Fortunately it seems these in WebRTC and
D3D11 are the only ones matching the non-@-prefixed pattern:

    ^ \* GST_\w+:\s*\w+

90181642a3 d3d11decoder: Resurrect zero-copy for fixed-size DPB pool
Enable zero-copy if downstream proposed pool and therefore decoder
can know the amount of buffer required by downstream.
Otherwise decoder will copy when our DPB pool has no sufficient
buffers for later decoding operation.

39b9f79e11 d3d11: Implement memory pool
Major changes:
* GstD3D11Allocator: This allocator is now device-independent object
  which can allocate GstD3D11Memory object for any GstD3D11Device.
  User can get this object via gst_allocator_find(GST_D3D11_MEMORY_NAME)
* GstD3D11PoolAllocator: A new allocator implementation for texture pool.
  From now on GstD3D11BufferPool will make use of this memory pool allocator
  to avoid frequent texture reallocation. That usually happens because
  of buffer copy (gst_buffer_make_writable for example)

In addition to that, GstD3D11BufferPool will provide GstBuffer with
GstVideoMeta, because CPU access to a GstD3D11Memory without GstVideoMeta
is almost impossible since GPU drivers needs padding for stride alignment.

640a65bf96 gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

824b0ce0f4 Revert "d3d11: Enable native multi-thread protection layer and make use of it"
This reverts commit 872b7f503c.

Native multi-thread protection layer seems to be consuming more CPU
resource than application side protection approach in some cases

872b7f503c d3d11: Enable native multi-thread protection layer and make use of it
... instead of our own GRecMutex locking. In this way, any other
Direct3D11 client (MediaFoundation for example) can safely call
any Direct3D11 API even when we are sharing our Direct3D11 device
with others.

615f52f2f7 d3d11device: Hold ID3D11VideoDevice and ID3D11VideoContext object
... instead of QueryInterface-ing per elements. Note that
ID3D11VideoDevice and ID3D11VideoContext objects might not be available
if device doesn't support video interface.
So GstD3D11Device object will create those objects only when requested.

12baab442c d3d11memory: Add a method for querying texture array size
... and the number of textures in use.

Direct3D11 texture array is usually used for decoder DPB pool,
and d3d11 decoder elements might want to know
whether there's available texture resource or not.

0b0bf1b0bf d3d11: Suppress some warning debug messages
* Don't warn for live object, since ID3D11Debug itself seems to be
  holding refcount of ID3D11Device at the moment we called
  ID3D11Debug::ReportLiveDeviceObjects(). It would report live object
  always
* Device might not be able to support some formats (e.g., P010)
  especially in case of WARP device. We don't need to warn about that.
* gst_d3d11_device_new() can be used for device enumeration. Don't warn
  even if we cannot create D3D11 device with given adapter index therefore.
* Don't warn for HLSL compiler warning. It's just noise and
  should not be critical thing at all

d16b5b7f7f d3d11: Allow building UWP features with Desktop features if possible
WINAPI_PARTITION_DESKTOP and WINAPI_PARTITION_APP can coexist.

this change will be useful for development stage

0f7af4b143 d3d11: Move core methods to gst-libs
Move d3d11 device, memory, buffer pool and minimal method
to gst-libs so that other plugins can access d3d11 resource.
Since Direct3D is primary graphics API on Windows, we need
this infrastructure for various plugins can share GPU resource
without downloading GPU memory.
Note that this implementation is public only for -bad scope
for now.
