14062c06a6 nvdecoder: Use own CUDA stream in GL output path
Use the same CUDA stream passed to CuvidMapVideoFrame()

9914ff9b4c nvdec: Don't use default CUDA stream
NVDEC launches CUDA kernel function (ConvertNV12BLtoNV12 or so)
when CuvidMapVideoFrame() is called. Which seems to be
NVDEC's internal post-processing kernel function, maybe
to convert tiled YUV to linear YUV format or something similar.

A problem if we don't pass CUDA stream to the CuvidMapVideoFrame()
call is that the NVDEC's internel kernel function will use default CUDA stream.
Then lots of the other CUDA API calls will be blocked/serialized.

To avoid the unnecessary blocking, we should pass our own
CUDA stream object to the CuvidMapVideoFrame() call

111b2c3f53 nvcodec: Refactor GstCudaMemory abstraction
* Hide GstCudaMemory member variables
* Make GstCudaAllocator object GstCudaContext independent
* Set offset/stride of memory correctly via video meta
* Drop GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT support.
  This implementation actually does not support custom alignment
  because we allocate device memory via cuMemAllocPitch
  of which alignment is almost uncontrollable

80bbc71ec0 nvdecoder: Fix for HEVC 4:4:4 format decoding
Map chroma_format_idc == 3 (which means 4:4:4 subsampling) correctly,
also pass coded bitdepth for decoder initialization instead of
inferring it from output format since they can be different.

34b54ca665 nvdecoder: Fix for display resolution setup
Display resolution should be cropped rect, not coded resolution.
Otherwise decoded output from NVDEC might be wrong.
