nvjpegEncodeYUV NVJPEG_STATUS_INVALID_PARAMETER #23

Open gangdelian opened 4 years ago

gangdelian commented 4 years ago

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?

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： image

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.
