Sorry, I don't understand this. This is a decoder, so based on the bitstream it decodes to a certain width and height. I assume that is what you refer to as coded_width and coded_height? If so, then what is the 'real display region' and how does it relate to the coded width/height? This is probably a terminology issue but I need to understand this before I can decide what should be done here.

Coded resolution is stream resolution in pixels aligned to codec format and hardware requirements. And we assign bytesperline as coded_width. g_selection is for getting visible resolution for user space. visible resolution - stream resolution of the visible picture, in pixels, to be used for display purposes; must be smaller or equal to coded resolution; visible height - height for given visible resolution visible width - width for given visible resolution For my understand, g_fmt should return coded width/height in pix_mp->width, pix_mp->height. And bytesperline is coded with. g_selection return visible width/height.
