df64226e71 d3d11decoder: Do timer based DecoderBeginFrame retry
... instead of retry count based one, because the precision of Sleep()
varies depending on system and application configuration.
Also, don't retry DecoderBeginFrame if decoder is doing flush.

e1fd0f620f d3d11decoder: Add support for non-zero crop-{x,y} position
AVC and HEVC define crop rectangle and the x/y coordinates might
not be zero. This commit will address the non-zero x/y offset coordinates
via GstVideoCropMeta if downstream supports the meta and d3d11 memory.
Otherwise decoder will copy decoded texture into output frame.

9b128f1841 d3d11decoder: Don't print error log on negotiation failure
It may not be a critical error and even expected when shutting down
pipeline or flushing.

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.

6434d69f8c codecs: Stop claiming constness for refcounted object
It's almost pointless and makes little sense as subclass might
want to modify refcount of the object or so. And all subclasses
are already casting them to non-const version as well.
In a general sense, we need to avoid passing refcounted object
with const qualifier.

7fe08d8bed d3d11: Stop doc for non-default decoder and deinterlacer elements
Just skip doc for non-default decoder/deinterlacer elements
since there are multiple element in case that system has
multiple GPUs.

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.

e322745763 codecs: h264decoder: Use GstFlowReturn everywhere
boolean return value is not sufficient for representing the reason
of error in most cases. For instance, any errors around new_sequence()
would mean negotiation error, not just *ERROR*.
And some subclasses will allocate buffer/memory/surface on new_picture()
but it could be failed because of expected error, likely flushing
