I’d like to convert uyuv 422 packed into RGBA image with NvMedia2DBlitEx() function?
I get this error during execution:
sConvertSurface: Blit error: 0x6
nvmedia: ERROR: NvMedia2DBlitEx 7

Input image is defined as:
NVM_SURF_FMT_SET_ATTR_YUV(outSurfFormatAttrs, UYVY, 422, PACKED, UINT, 8, PL);

For test i read (NvMediaImageCreateNew) a RGBA image and convert it with NvMedia2DBlitEx() function to a RGBA image, works fine.
I also tried reading and writing the uyuv 422 packed image. The written image is the same as the input image. It works also fine. But adding the NvMedia2DBlitEx() function a get the error message.

Supports NvMedia2DBlitEx the input format “uyuv 422 packed” ?


It appears that it is not supported. I suggest consulting the NvMedia2DBlitEx() API for more information.

Thank you for your answer.
Sorry but i don’t find information in the API docu NvMedia2DBlitEx() which formats are supported.
But if NvMedia2DBlitEx() does not supports the “uyuv 422 packed” image format, how i can get my image into the NvMedia or Driveworks pipeline?
In my usecase, i get "uyuv 422 packed” images over an ethernet data stream. After decoding the images i would like do some image processing (lane detection…) with the driveworks API. But i see, that driveworks don’t support packed YUV image format. So i tried the NvMedia2DBlitEx function. I also see, that in the TRM of Xavier SOC the “uyuv 422 packed” image format should be supported.
Can you give me a hind to get the “uyuv 422 packed” image into the driveworks or NvMedia pipeline?
Thank you in advance.
