hi，

目前我们相机部分占用CPU和GPU资源较高，所以想使用非CUDA方式进行转化，想请教一下几个问题，是否有相关的示例代码？

硬件为：Jetson Orin 64GB，software: JetPack5.1.3

1、YUV422转YUV420是否可以用非CUDA方式实现，如VIC？

2、YUV420缩放及去畸变是否可以用非CUDA方式实现，如VIC？

3、YUV422是否可以直接转换RGB格式？用非CUDA方式

谢谢

Based on the provided context, I will answer the question by comparing the supported output formats for VIC-based nvvidconv and CUDA-based nvvidconv on Jetson AGX Orin.

VIC-based nvvidconv

The VIC-based nvvidconv on Jetson AGX Orin supports the following RAW-YUV output formats:

  1. I420

  2. UYVY

  3. YUY2

  4. YVYU

  5. NV12

  6. NV16

  7. NV24

  8. GRAY8

  9. BGRx

  10. RGBA

  11. Y42B

CUDA-based nvvidconv

The CUDA-based nvvidconv on GPU supports the following RAW-YUV output formats:

  1. I420

  2. NV12

  3. P010_10LE

  4. I420_10LE

  5. GRAY8

  6. BGRx

  7. RGBA

Comparison

Comparing the two lists, we can see that:

  • Both VIC-based and CUDA-based nvvidconv support I420, NV12, GRAY8, BGRx, and RGBA output formats.

  • VIC-based nvvidconv supports additional output formats, including UYVY, YUY2, YVYU, NV16, NV24, and Y42B.

  • CUDA-based nvvidconv supports P010_10LE and I420_10LE output formats, which are not supported by VIC-based nvvidconv.

Answer to the question

Based on the comparison, we can conclude that:

  • YUV422 is supported by VIC-based nvvidconv (UYVY, YUY2, and YVYU) but not by CUDA-based nvvidconv.

  • YUV420 is supported by both VIC-based and CUDA-based nvvidconv (I420 and NV12).

  • RGB is supported by both VIC-based and CUDA-based nvvidconv (BGRx and RGBA).

Therefore, the correct answer is:

  1. YUV422: VIC

  2. YUV420: Both VIC and CUDA

  3. RGB: Both VIC and CUDA

hi,

可以提供VIC的相关示例代码吗？

抱歉刚刚描述有点问题，我们的设计是从YUV422最终转成BGR格式

We don’t public the source but provide API.

hi

请问那我们应该如何用起来呢？？

没有参考代码吗

You can check the MMAPI sample code.
