下面是我初始化filter的部分代码，看起来是没问题的，device_ref 也有设置，为什么最终跑起来时候，会爆这个错误？

以下是错误代码：

It should be the lack of setting the hardware context for the filter.

Search hw or filter_hw_device or hw_device_for_filter in these codes:

不使用hwupload 过滤器，仅仅使用vpp_rkrga过滤器可以实现crop和yuv->rgb24的格式转换吗？

Nope. hwupload is a must have filter for memory input.

memory ->(hwupload)-> hardware DMA-BUF -> RGA -> ...
