On Linux, can a process render a different GUI for a process?

I am writing a video player in Linux and I would like to divide it into 2 processes:

a. B. GUI decoder

Thus, I could use different programming languages, and when a problem arises, it is easier to find out where the problem is.

The problem is, can it process decoded rendering images directly on surface B? I do not want to use some IPC to send B this decoded data, because it can be very inefficient.

if(p == MAP_FAILED) abort()

See how mplayer and smplayer are implemented. mplayer decodes and displays the video, while smplayer decodes the (optional) graphical interface.
