I use nvm_ide_sci to capture an image, I set the type as BlockLinear in NvSciBuf, I don’t want to use VIC to convert to PitchLinear, I want to deal with it directly with cuda, please ask how to parse the format of BlockLinear with cuda。

Dear @haihua.wei,
As I understand you want to use NvSciBuf with CUDA directly for further processing. Does cudaNvSci sample(/usr/local/cuda/samples/0_Simple/cudaNvSci) helps for your case?

Okay, I’ll take a look at this

Sample is NvSciBufImage_PitchLinearType,but we want NvSciBufImage_BlockLinearType

Dear @haihua.wei,
I see below snippet in sample. Could you confirm?

void setImageBufAttrList(uint32_t width, uint32_t height) {
NvSciBufType bufType = NvSciBufType_Image;
NvSciBufAttrValImageLayoutType layout = NvSciBufImage_BlockLinearType;
NvSciBufAttrValAccessPerm perm = NvSciBufAccessPerm_ReadWrite;

See, let’s look into it
