10f622aa5d d3d11convert: Use ID3D11VideoProcessor only if device supports colorspace
Check whether conversion with given combination of input/output
format and dxgi colorspace is supported or not by driver.
If not, we should use shader.

969ab3e664 d3d11convert: Add support for conversion using ID3D11VideoProcessor
Output texture of d3d11 decoder cannot have the bind flag
D3D11_BIND_SHADER_RESOURCE (meaning that it cannot be used for shader
input resource). So d3d11convert (and it's subclasses) was copying
texture into another internal texture to use d3d11 shader.
It's obviously overhead and we can avoid texture copy for
colorspace conversion or resizing via ID3D11VideoProcessor
as it supports decoder output texture.
This commit would be a visible optimization for d3d11 decoder with
d3d11compositor use case because we can avoid texture copy per frame.

eecb130bd9 d3d11convert: Add new subclasses for only color convert or resize
New d3d11colorconvert and d3d11scale elements will perform only
colorspace conversion and rescale, respectively. Those new elements
would be useful when only colorspace conversion or rescale is required
and the other part should be done by another elements.

ea24a2e527 d3d11: Add support for packed 8bits 4:2:2 YUV formats
Note that newly added formats (YUY2, UYVY, and VYUY) are not supported
render target view formats. So such formats can be only input of d3d11convert
or d3d11videosink. Another note is that YUY2 format is a very common
format for hardware en/decoders on Windows.

a24d4e654d d3d11: Add support for video rescale and rename element to d3d11convert
GstD3D11ColorConverter implementation is able to rescale video as well.
By doing colorspace conversion and rescale at once, we can save
one cycle of shader pipeline which will can save GPU resource.

Since this element can support color space conversion and rescale,
it's renamed as d3d11convert

96f0f4b613 d3d11memory: Always use native DXGI format if device support it
Use consistent memory layout between dxva and other shader use case.
For example, use DXGI_FORMAT_NV12 texture format instead of
two textures with DXGI_FORMAT_R8_UNORM and DXGI_FORMAT_R8G8_UNORM.

9ee40679b5 Revert "d3d11: Add support for D3D11_USAGE_DYNAMIC"
This reverts commit ddd13fc7c0

Dynamic usage can reduce the number of copy per frame but make
things complicated and the benefit seems to not significant.
Also since we don't provide _map() method for the dynamic usage,
application cannot read buffers which make "last-sample" property
unusable in case of d3d11videosink.

81dde0f5b8 d3d11: Aggregate d3d11 memory usage query for dynamic-usage type decision
Even if one of downstream d3d11 elements can support dynamic-usage memory,
another one might not support it. Also, to support dynamic-usage,
both upstream and downstream d3d11device must be the same object.

d731bcb18a d3d11colorconvert: Remove device type dependent behavior
If d3d11colorconvert element is configured, do color space conversion
regardless of the device type whether it's S/W emulation or real H/W.
Since d3d11colorconvert is no more a child of d3d11videosinkbin,
we don't need this behavior. Note that previous code was added to
avoid color space conversion from d3d11videosink if no hardware
device is available (S/W emulation of d3d11 is too slow).

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.

61cb6b2bbe d3d11: Pass GstD3D11Memory object to ensure_{shader_resource,render_target}_view methods
The method name indicates it should be d3d11memory, so passing
GstD3D11Memory seems to make more sense than GstMemory.
