2cd81eb1ac nvdecoder: Handle output surface alignment in decoder helper object
Output resolution might not be an even number. Set output resolution
without round up but consider the alignment inside of decoder

42560c24df nvdecoder: Add support for D3D11 output
Since DXVA does not support some profiles such as HEVC RExt,
vendor specific decoding API is still required.
When decoder is negotiated with d3d11 caps, decoder will convert
semi-planar frame to planar since semi-planar format (e.g.,
DXGI_FORMAT_NV12) is not supported by CUDA/D3D11 interop.

bd25c2738e nvdecoder: Copy output frame if needed
Even if decoder is negotiated with CUDA memory feature, if downstream
proposed no buffer pool, assume that the pool size is unknown.
And disable zero-copy if there's no more free output surface.
Or, in case of reverse playback, always copy frames.

19ee5f6dc4 nvdecoder: Reduce DPB size
Decoder will copy decoded picture to downstream buffer or output CUDA
memory even in case of zero-copy mode. Additional margin should be unnecessary
unless baseclass passed wrong max DPB size.

f831b92540 nvdecoder: Add support for reconfiguration
Instead of creating new decoder instance per new sequence,
re-use configured decoder instance via cuvidReconfigureDecoder()
API. It will make output surface reusable without re-allocation.
Also, in order for application to be able to reserve higher resolution
output surface, "init-max-width" and "init-max-height" properties are
added to each decoder.

03425bc702 nvdecoder: Add support for CUDA zero-copy in stateless decoder
Wrap mapped decoder output surface using GstCudaMemory and
output without any copy operation. Also, for application to be able to
control the number of zero-copyable output surfaces,
"num-output-surfaces" property is added.
