afe941249e d3d11window: Add unprepare method to clear internal resource
GObject::dispose method can be called multiple times. As win32 d3d11window
has an internal thread and because GObject::dispose method could be called from the
thread, it might cause problems such as trying to join self-thread

f9f6916aa1 d3d11window: Reorganize display colorspace selection
The set of supported color space by DXGI is not full combination of
our colorimetry. That means we should convert color space to one
of supported color space by DXGI. This commit modifies the color space
selection step so that d3d11window can find the best matching DXGI color space
first and then the selected input/output color space will be referenced
by shader and/or d3d11videoprocessor.

9b7c20bfca d3d11videosink: Clarify the meaning of various width and height variables
* Remove redundant variables for width/height and par from GstD3D11Window.
  GstVideoInfo holds all the values.
* Don't need to pass par to gst_d3d11_window_prepare().
  It will be parsed from caps again
* Remove duplicated math

Fixing regression of the commit 9dada90108

2aa9f0bd6c d3d11window: Don't create swapchain again per caps change
Creating swapchain is relatively heavy operation. If output dxgi format
is not being chagned, we don't need to destroy and create swachain again.

c1d2d9171d d3d11window: Invoke initial resize method from baseclass
... instead of calling from subclass in order for baseclass to handle
more things between swapchain creation and resource creation.

7aad9187e4 d3d11videosink: Use ID3D11VideoProcessor interface
...for color space conversion if available

ID3D11VideoProcessor is equivalent to DXVA-HD video processor
which might use specialized blocks for video processing
instead of general GPU resource. In addition to that feature,
we need to use this API for color space conversion of DXVA2 decoder
output memory, because any d3d11 texture arrays that were
created with D3D11_BIND_DECODER cannot be used for shader resource.

This is prework for d3d11decoder zero-copy rendering and also
for conditional HDR tone-map support.
Note that some Intel platform is known to support tone-mapping
at the driver level using this API on Windows 10.

5298d95195 d3d11window: Make use of partial presentation with IDXGISwapChain1::Present1
Since we might draw on partial area of backbuffer in case of force-aspect-ratio,
presenting only updated area is more efficient way.

1b687d556a d3d11videosink: Add support for full screen mode
borderless top-most style full screen mode support.
Basically fullscreen toggle mode is disabled by default. To enable it
use "fullscreen-toggle-mode" property to allow fullscreen mode change
by user input and/or property.

0788492461 d3d11: Use GRecMutex to protect immediate context and dxgi API call
In some cases, rendering and dxgi (e.g., swapchain) APIs should be
called from window message pump thread, but current design (dedicated d3d11 thread)
make it impossible. To solve it, change concurrency model to locking based one
from single-thread model.

9dada90108 d3d11videosink: Remove resizing window hack and unify resizing flow
In earlier implementation of d3d11videosink where no shader was implemented,
the aspect ratio and render size were adjusted by manipulating the backbuffer size
with unintuitive formula. Since now we do color conversion and resize using
shader, we can remove the hack.

64eb1d46b5 d3d11window: Always draw to internal window
... and use SetParent() WIN32 API when external window is used.
Depending on DXGI swap effect, the external window might not be
reusable by another backend. To preserve the external window's property
and setting, drawing to internal window seems to be safer way.

9835289239 d3d11window: Do not check shader resource view if not doing conversion
If d3d11window does not convert format internally, shader resource view
is not required. Note that shader resource view is used for
color conversion using shader but when conversion is not required,
we just copy input input texture to backbuffer.

ca3ddf7848 d3d11videosink: Add color conversion support
Draw to back buffer texture directly. It would reduce the number of
copy at least once when color conversion is required.

5909a495a7 d3d11videosink: Take into account pixel aspect ratio
Fix unexpected cropping with non 1:1 pixel aspect-ratio.

The actual buffer width/height should be passed to gst_d3d11_window_render(),
instead of the calculated resolution. The width/height
values are parameters for copying d3d11 video memory.
Also, aspect-ratio should be considered on resize callback
to decide render rectangle size.

5c3879ace6 d3d11videosink: Add new Direct3D11 video render plugin
Direct3D11 was shipped as part of Windows7 and it's obviously
primary graphics API on Windows.

This plugin includes HDR10 rendering if following requirements are satisfied
* IDXGISwapChain4::SetHDRMetaData is available (decleared in dxgi1_5.h)
* Display can support DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 color space
* Upstream provides 10 bitdepth format with smpte-st 2084 static metadata
