I use nvm_ide_sci to decode video, I want to use NvSciBuf data directly for further processing, but it’s Blocklinear, how can I get data in NvSciBuf with right format. I try use funciton NvSciBufObjGetPixels, it takes too long and I want get image in NV12 format.

Could you please specify where in the source of nvm_ide_sci you are looking to verify that the decoded data is Blocklinear?

In file scibuf_utils.c line 1682, I print NvSciBufImageAttrKey_Layout value equal NvSciBufImage_BlockLinearType

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

It looks like you checked the type in the WriteOutput() function, is that correct? As far as I know, nvm_ide_sci writes to the file in pitch linear 420p format. Could you please share your full nvm_ide_sci command for further investigation?
