Process YUV422 image using gpu instead of VIC

We need to process six images almost at the same time, and the usage of VIC is nearly 100%.

Can we use the gpu to process image instead? We want to resize the images and convert from yuv422 to yuv420 to encode.

Is there any samples ?

Thanks.

Hi,

If you are designing a custom base board, then it means some adaptation configurations are needed.
Otherwise, your board may not work fine.

For Orin AGX series, you could refer to below document
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=universal%20serial%20bus#jetson-agx-orin-platform-adaptation-and-bring-up
(please be aware that above link is for rel-36.3/jetpack6.0)

This document includes below configuration

  1. pinmux change & GPIO configuration
  2. EEPROM change as most custom boards do not have an EEPROM on it.
  3. Kernel porting
  4. PCIe configuration
  5. USB configuration
  6. MGBE configuration
  7. RGMII configuration

Thanks!

Will this configuration affect my use of GPU for image processing?

Hi,
There is no existing code for converting YUV422 to YUV420. You would need to implement the function. Possible solution is like:

  1. Allocate NvBufSurface in YUV422 and YUV420
  2. Call NvBufSurface to get CUDA pointer
  3. Implement CUDA code to do the conversion

Hi,
Is it possible to use API NvBufSurfTransform with the NvBufSurfTransformCompute_GPU to do the conversion?

Hi,
It may not be well ready on certain Jetpack versions. If you use Jetpack 6.1, please give it a try.

Hi,

How to call NvBufSurface to get CUDA pointer?
