Hi, Can you attached the sample images where you seen this error.
For quick debugging, just add these line at nvJPEG_encoder.cpp:193
subsampling = NVJPEG_CSS_GRAY;
checkCudaErrors(nvjpegEncoderParamsSetSamplingFactors(encode_params, NVJPEG_CSS_GRAY, NULL));
Test it, let me now your finding.
This is my test project, hope it will help you.

Hi,
I've checked the code nvJPEG_encoder.cpp:line 197
change to subsampling
variable.
checkCudaErrors(nvjpegEncodeYUV(nvjpeg_handle,
encoder_state,
encode_params,
&imgdesc,
subsampling,
widths[0],
heights[0],
NULL));
Tested encoder with following input arguments on GV100: -i img1.jpg (4x4, Sampling 4:2:0) -o /tmp/ -s 400 // for GRAY conversion
Input image details: File Name : img1.jpg File Size : 695 bytes Encoding Process : Baseline DCT, Huffman coding Bits Per Sample : 8 Color Components : 3 Y Cb Cr Sub Sampling : YCbCr4:2:0 (2 2) Image Size : 4x4
Output image details: File Name : img1.jpg File Size : 357 bytes Encoding Process : Baseline DCT, Huffman coding Bits Per Sample : 8 Color Components : 1 Image Size : 4x4

Yes, I want to encode to a gray image. So I specify NVJPEG_CSS_GRAY as subsampling. You can also test my new demo from here,the img1.jpg which i convert to 4x4 gray image,and will get following errors:

This error due to source image plane pitch is not divisible by 8. In current GPU implementation source image plane should be divisible by 8 to achieve GPU speedup.

Thanks, hope this limits can be wrote in documents
Hi, I use the sample named nvJPEG_encoder, and I use NVJPEG_CSS_GRAY as subsampling format to encode an image size(4x16), will get below error: CUDA error at d:\cppworkspace\cuda-samples\samples\nvjpeg_encoder\nvjpeg_encoder.cpp:200 code=2(NVJPEG_STATUS_INVALID_PARAMETER) "nvjpegEncodeYUV(nvjpeg_handle, encoder_state, encode_params, &imgdesc, subsampling, widths[0], heights[0], NULL)" I found if use the image width smaller than 8, use NVJPEG_CSS_GRAY encode an image will fail. Is there some limits when encode an image?
