fe64295841 d3d11decoder: Work around Intel DXVA driver crash
Intel DXVA driver crashes sometimes (from GPU thread) if
ID3D11VideoDecoder is released while there are outstanding view objects.
To make sure the object life cycle, holds an ID3D11VideoDecoder refcount
in GstD3D11Memory object.

858520932c d3d11decoder: Add hardcoded minimum resolution values to caps for NVIDIA
NVIDIA GPUs have undocumented limitation regarding minimum resolution
and it can be queried via a NVDEC API. However, since we don't want to
bring CUDA/NVDEC API into D3D11, use hardcoded values for now
until we find a nice way for capability check.

dd32e2efbc d3d11decoder: Do not preallocate texture using downstream d3d11 buffer pool
Our decoder implementation does not use downstream d3d11 pool for
decoding because of special requirement of D3D11/DXVA. So preallocation
using the downstream buffer pool will waste GPU memory in most cases.

b5a8bef5a7 d3d11decoder: Copy HDR10 related caps field manually
If negotiate() is called from the set_format() chain, sinkpad may not
hold caps yet, so baseclass cannot copy it over to srcpad caps.
Copy them manually.

2548014dfc win32: Enable high-resolution timer for MinGW build
timeapi.h is missing in our MinGW toolchain. Include mmsystem.h
header instead, which defines struct and APIs in case of our MinGW
toolchain. Note that in case of native Windows10 SDK (MSVC build),
mmsystem.h will include timeapi.h

dd906f9610 d3d11: Store device format in struct
Holding pointer to struct was unsafe approach because
the pointer to d3d11 format will be invalidated once d3d11 device
object is released

b22aa14e43 d3d11decoder: Use staging buffer pool for non-d3d11 downstream
In specific condition, this can show about 10% ~ 30%
performance gain with non-d3d11 downstream element.

5fefc689a0 d3d11decoder: Negotiate again on the first output buffer
... unconditionally. There may be updated field in sinkpad caps
after the new_sequence() call (HDR related ones for example),
then we should signal the information to downstream.

5707e487cf d3d11: d3d11decoder: Use DXGI adapter LUID
... instead of index of DXGI adapter.

The order of IDXGIAdapter1 enumerated via IDXGIFactory1::EnumAdapters1
can be varying even there's no rebooting in case that GPU preference order
is updated by user (for example, it can be done by using NVIDIA Control Panel
in case of multi-GPU laptop system) and eGPU is another possible case.

So, for an element which requires fixed target GPU requirement,
index based device enumeration is unreliable.
