You can of course pass it to the MPlayer internas as 8bit greyscale, which would be IMGFMT_Y8 or just pass it on as 16bit which would be IMGFMT_Y16_LE (LE = little endian). You can find the internal #defines of the image formats in libmpcodecs/img_format.h and can use https://www.fourcc.org/yuv.php to decode their meaning. The equivalent for libav would be libavutil/pixfmt.h Luca Barbato tells me that adding Y12 support to libav would be easy.
