NVCODEC

I use NVENC and NVDEC to deal with 16bit medical image

Tip. My project is different from NVIDIA CODEC. I modified the source code to make it suitable for grayscale images (only for grayscale images).

Specifically, we modified ".../Samples/AppEncode/AppEncCuda/AppEncCuda.cpp" to control the encoder, and modified ".../Samples/AppDecode/AppDec/AppDec.cpp" to control the decoder. Different modifications are shown here.

my computer

windows10
cuda 9.2
opencv 3.0.0
vs2015

compiled appplication(There are some troubles)

.../NVCODEC/Comiled application
There are some samples: .\AppEncCuda.exe -h
You will watch help. The same as to AppDec.exe. .\AppDec.exe -h

encoder

.\AppEncCuda.exe -i path_16bit -o ...\high.mkv -o2 ...\low.mkv -s 2048x788 -num 754 -if nv12 -gpu 0 -codec hevc -preset default -profile main -rc vbr_hq -fps 25 -gop 150 -qmin 1 -qmax 31
"-i" store original files in the directory (5-dimensional dataset encapsulated in OME-TIFF, such as Raw.ome.tif)
"-o" encoded high 6/8/10bits
"-o2" encoded low 6/8/10bits
"-s" image size(default: 2048x788) "-if" color format(don't change it)
"-gpu" choose a nvidia gpu(hevc needs more than GTX 950)
"-codec" choose encoder type(hevc h264)
"-qmax" I\P\B qmax

decoder

.\AppDec.exe -i ...\high.mkv -i2 ...\low.mkv -o2 path_16bit -gpu 0
"-i" encoded high 6/8/10bits
"-i2" encoded low 6/8/10bits
"-o2" restored images "-gpu" choose a nvidia gpu(hevc needs more than GTX 950)

And you don't need care decoder parameters usually.

Source code(.../NVCODEC/CODE/)

I have little right to submit all codes. So you need to download official sources, if you have no account for NVIDIA. Check it.
Please instead "...\Video_Codec_SDK_8.2.16\Samples\AppEncode\AppEncCuda\AppEncCuda.cpp" with mine. "...\Video_Codec_SDK_8.2.16\Samples\AppDecode\AppDec\AppDec.cpp" is same.
By the way, don't forget OpenCV config in VS.
