I want to import the most different formats of video/images, but I want to work only with RGB24. I think for some reason img_convert deprecated(the compiler can not find this function). Know any other function (or way) that does exactly that?

You can use libswscale. Look at sws_getContext(), sws_scale(). You can
pass the decoded frame to sws_scale(), and the frame you want to copy
and convert it into. For this new frame, you'll probably want to
allocate memory for the frame's data using avpicture_fill().
