Threwing some (bad?) idea:
bgr4_byte -> B4BY
rgb4_byte -> R4BY
gray16be -> G16B
gray16le -> G16L
yuva420p -> Y[42][0]A
yuv420p16le ->[42][0][16]L
yuv420p16be ->[42][0][16]B
yuv422p16le ->[42][0][16]L
yuv422p16be ->[42][2][16]B
yuv444p16le ->[44][4][16]L
yuv444p16be ->[44][4][16]B
rgb444be ->R[44][4]B
rgb444le ->R[44][4]L
bgr444be ->B[44][4]B
bgr444le ->B[44][4]B
y400a ->Y[40][0]A
