RK3568 Camera Driver - Interlaced Mode Only Supported in Selfpath

Chip Platform Rockchip
1

Type: Self-Compiled Firmware
SDK Package Name: Firefly-RK356X_Android11.0_git_20210824
Modification Content: hardware/rockchip/camera

Hi everyone,

I’m currently working on a camera driver using the RK3568 SDK and have modified the kernel to support interlaced mode. According to the documentation, interlaced mode should be supported in the selfpath, and I have set the field parameter as follows:

.field = V4L2_FIELD_INTERLACED,

However, when I run the camera in the Android environment, I only get the following log message:

only selfpath support interlaced

Questions:

  • Has anyone encountered this issue before?
  • Are there any additional configurations required for interlaced mode in RK3568?
  • Could this be a limitation in Android’s Camera HAL or a driver-level issue?

Any insights or suggestions would be greatly appreciated!

Thanks in advance. :rocket:
