Hello,
The premise is that the camera you use can support 480p
Do you want to modify Back camera video or Front camera video? We only have HD 1080p, HD 720p, SD 480p for Back camera video, and we only have HD 1080p for Front camera video, you can choose in Resolution&quality of Setting in Camera app
Or you want to fix the adapter node, isp node, isp_cma node to the resolution of your camera sensor in dts
The above picture shows the example of 1920x1080 and 3840x2160 as an example, you can change it to the resolution you need
