I have a 2 imx678 hires cameras attached to a voxl 2 mini the stream video using the voxl-camera-server without any problems, however there is a weird color tint on the cameras. Is there any way to adjust to color calibration for the voxl-camera-server? If not is there a way to access the raw8 or raw10 grey video without any image processing done to them?

@mkriesel we are working on a method for accessing RAW8 for the high-resolution image sensors now. We hope to have something on dev by the end of the month

@Moderator Any update on accessing the RAW8 for the hires image sensors? 
Also, is there a way to change the exposure and gain manually. In the voxl-camera-server config I have been able to change the setting of ae_mode to off and I've tried using the "voxl-send-command hires0_small_color set_exp_gain 100 200" for example but nothing changes. I also tried setting the ae_mode to lme_msv but changing the settings in the config had no effect of the exposure or gain either, it was acting the same as the off mode. Are these settings available to the hires imx678? If not, is there any way for me to adjust the exposure and gain settings?

@mkriesel I wonder if that is the reason why IMX678 product on modalai show as out-of-stock at the moment. I contacted FRAMOS and they told me that they did not develop the driver for the sensor but modalai probably did it themselves.
