使用nonai_2d的CRC功能进行图像类型转换，nonai_2d模块的要如何使用？

我希望使用nonai_2d的CRC功能进行图像类型转换，参考sample_mcm例程添加了对应的start和exit，并且做了sys_bind,也申请了vb，但是运行之后系统一直提示类似没有缓冲区的报错，请教一下nonai_2d模块的要如何使用，vb的申请有什么原则吗

通过您的代码，我了解到您从sensor获取两路数据流：一路是用于VO显示的yuv420sp格式，另一路是用于AI分析的rgbp888格式。
如果您的需求是这样，不需要使用nonai_2d进行格式转换，因为sensor支持yuv420sp和rgbp888格式输出。
        nonai_2d的具体使用方法：
请仔细阅读 sample_mcm 代码，里面已经包含了 nonai_2d 的详细使用方法。
以下是 sample_mcm 代码中 nonai_2d 的具体使用思路。更详细的内容需要阅读 API 接口文档和 demo 来掌握。
1. 初始化 nonai_2d 通道

参照 nonai_2d_start 函数，内部会创建并启用 nonai_2d 通道：
kd_mpi_nonai_2d_create_chnkd_mpi_nonai_2d_start_chn2. 启动 nonai_2d 数据转换

2.1 绑定模式

如果 nonai_2d 仅用于处理 pipeline 数据流，且用户层不需要获取转换后的数据，则可以使用绑定模式。例如：

• 在内核态实现 sensor 数据显示到 VO：vicap(yuv422) -> nonai_2d(yuv420sp) -> vo
  
• 在内核态实现 sensor 数据编码：vicap(yuv422) -> nonai_2d(yuv420sp) -> venc
  

使用 kd_mpi_sys_bind 实现此功能。
2.2 非绑定模式

如果用户层需要获取 nonai_2d 转换后的数据流，则不能使用绑定模式。例如：

• 在 sample_mcm 代码中，如何把 sensor 数据传输给 AI 模块，参照 nonai_2d_work 函数，NONAI_2D_RGB_CH 通道用于此功能。
  
• 将 vicap(yuv422) 数据流通过 nonai_2d 转换为 rgbp888，并在用户层传输给 AI 模块使用：vicap(yuv422) -> nonai_2d(rgbp888)
  
• 使用以下接口发送和获取转换后的图形数据：kd_mpi_nonai_2d_send_framekd_mpi_nonai_2d_get_frame
