 Summary of the bug:
 Encoding pix_fmt GBRP10LE rawvideo in a NUT container produces RGB555LE
 files (without saying so).
 Playing the resulting file with ffplay displays wrong colors: Everything
 is blue/green.

 How to reproduce:

 $ ffmpeg_git -f lavfi -i mandelbrot -t 1 -f nut -an -vcodec rawvideo
 -pix_fmt gbrp10le output.nut
