Demosaic IP output is incorrect

Hello, I used demosaic IP in my project, but unfortunately it didn't work

My quartus version is 24.2, I used demosaic IP in Platform, here are some of my settings:
Input bits per color sample: 10
Output bit per color sample: 8
Number of pixels in parallel: 4
Maximum field height: 1024
Maximum field width: 2048
No options in General are used

The main_clock of demosaic is 100MHz, axi4s_vid_in is connected to the video_streaming_interface_0 interface of MIPI CSI2 IP, and the data output by the video_streaming_interface_0 interface is normal, av_mm_control_agent is connected to nios v

But according to the waveform captured by signal tap, demosaic The IP output axi4s_vid_in_tready is always low, and the output axi4s_vid_out_tdata is always a fixed value, such as 000000000000000000909090h

I want to know how to use this IP correctly, any help is appreciated, thank you.
