pondering...

Unfortunatelly, it's like I said before:

Just because we can set some flag does not mean it triggers any functionality. Furthermore, these settings are very low level. For example, in photo mode:

st cap capdtm setvar TV 50 4

and then

st cap capdtm setvar TV 200 4

You will see no difference in markings of shutter speed, but it will change (see how the image got darker - 200 is 1/6000s). This means that we set a shutter speed (TV) register to something, T-KERNEL RTOS did it's thing but did not notify di-camera-app that the shutter speed has changed (because di-camera-app is supposed to control it, not the other way around).

just pondering... so probably every time we press "record" a new encoder object is created, based on current settings in di-camera-app, and the flags in memory related to encoder settings get rewritten (if used at all), before encoder initiates.
and that probably means affecting video-encoder settings will not be achievable this (st cap) way.

maybe using "sys_param" ? (we did see it able to change "movie size")
or if camera settings are saved on one of the separate partitions, (probably done for allowing safer firmware updates) and we modify those, on camera reset they will get loaded?
