removing the buggy av_log and adding AV_PIX_FMT_GRAY8 to the RGB
formats maintains the "working" status of this file

also the colour_space code is missing a sane error message if it
fails to find any pixel format (happens for some files)

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
