Description

Hi,

VideoWriter can receive RGB images but then the red and blue channels are switched. If VideoWriter receives a BGR image it writes it correctly.

Tested on version 2.4.3

The VideoWriter doesn't have info on the color channels order in the provided frames and assumes the conventional for the platform order (that is 'BGR' for Windows and Linux). So if I understand your description correctly this is not a bug but expected behavior.
Please re-open the issue if you meant something other that looks unnatural.

This is the case.

I think a proper description of this in the documentation would help.
