NvBufferImportFd Implementation

Hi, I’m implementing NvBufferImportFd in hopes it will faster than NvBufferTransformEx. I have the NvBufferParamsEx for the old NvBufferTransformEx call but copying the relevant parts to a new NvBufferParamsEx object for NvBufferImportFd doesn’t work. Is there psuedocode for how to implement NvBufferImportFd?

Please share how much performance you would like to achieve in the use-case, such as 4Kp30?

And NvBufferTransformEx() is done on hardware converter. Please execute the steps and see if there is improvement:
