          Used when decoding from multiple PNG or JPEG files.

          Available options are:

             w=<value>
                  input file width (default: autodetect)
             h=<value>
                  input file height (default: autodetect)
             fps=<value>
                  output fps (default: 25)
             type=<value>
                  input file type (available: jpeg, png, tga, sgi)

bmp is not mentioned so I would assume it's not supported.

mencoder is telling you the same thing.

Convert the picture to a supported format and mencoder will work.
