RKIPC configuration

2026-06-03 1:20

We now have the Luckfox RV1126B running rkipc providing video 1920X1080 @60fps from a IMX415 camera.

This post was very helpful in getting the ISP to work with the IMX415 in binned HD 60fps mode:

Can anyone point me to comprehensive documentation on these configuration parameters in rkisp.ini?

In particular, I am unable to enable_fec (fisheye distortion correction)
The rkisp log indicates:

Code: Select all

[isp.c][rk_isp_set_distortion_correction]:old_value is open, new value is open

But is later says:

Code: Select all

[video.c][rk_video_init]:enable_jpeg is 1, enable_venc_0 is 1, enable_venc_1 is 1, enable_fec is 0

I see no complaints about being unable to load mesh files.
rt_log_level=6

I have not tested or used any FEC-related features, but I think this might be related to the kernel configuration. Please refer to the appendix document (currently only a Chinese version is available; you can use translation software to read it).

Thank you for the prompt response!

Could you provide a link to the "appendix document" or its full title?

This is the FEC-related documentation.

Turns out, the FEC works fine after one sets this in rkisp.ini:

Code: Select all

[isp.0.enhancement] 
distortion_correction = FEC

distortion correction is normally a boolean. However, 'FEC' is a 3rd value reserved for use with the RV1126B. You don't get per stream selection. FEC is on for all streams or off for all.
