implementation of shutterspeed, awb red gain, awb blue gain in still mode

[manalito]

From my tests it works as expected. The only information to verify is the max value of the shutterspeed can be potentially higher but requires more tests or new informations to go higher

This is so great if true.👍 I'm doing some image acquisition and I need it to be fast and repeatable so I have to lock down all of the exposure white balance.
I'll give it a shot in the morning 😁

Is there a way to set the analog and digital gains too? The raspistill command has those options.

It would be nice if you included the non OpenCV version too. 👍 I was able to hack one using your example.

I'll look at this tomorrow, thank you for your comments

Concerning the analog and and digital gains, yeah, I am sure it's possible. Unfortunately, I tried a few months ago to implement these functions but I had some issues with MMAL library, probably because of my misunderstanding of the MMAL function used to edit these parameters.
