Is there any hardware accelerator for image 2D blit operation in jeston orin

[liuq1]

In jeston orin, do we have the hardware accelerator for image 2D blit operation? If we have, what is the api?

In the driveos, we have the NvMedia2DBlitEx to do this. I am not sure if we have such ability in jeston orin.

thanks.

Hi,
On Jetson platforms, the API is NvBufSurfTransform(). Please check document:
Jetson Linux API Reference: NvBufSurfTransform Types and Functions | NVIDIA Docs

After installing SDK Components through SDKManager, you will see samples in

/usr/src/jetson_multimedia_api

Please take a look and give it a try.

@DaneLLL

hrough SDKManager, you will see samples in

Thanks, i will take a try.
BTW, is the api using hardware to do the transform? It seems to use the gpu?

Hi,
It uses hardware converter VIC engine. Not GPU.

Thanks a lot.

One more question, is there any format in NvBufSurfaceColorFormat that support the 8bit yuv422 packed color space? I could not find such colore format in the enum NvBufSurfaceColorFormat. The header path is jetson_multimedia_api/include/nvbufsurface.h

[DaneLLL]

Hi,
NVBUF_COLOR_FORMAT_YUYV or NVBUF_COLOR_FORMAT_UYVY should be packed YUV422. You may try the formats.

If i use the v4l2 V4L2_MEMORY_MMAP memory type buffer to capture the camera image. It seems that i need to copy the data to an NvBuffer to use VIC, right?
