for bmp, no pipe variant would work reliable neither image2, image3
nor with or without individual AVInputFormats

in practice that would probably be dealt with by not autodetecting
bmppipe, the user still can specify it with -f bmppipe
and maybe he is lucky and his images work with the bmp parser

-f image2/3pipe wouldnt really help here or did you mean something
else ?
