Well, MPlayer should support them, though I have not tested with the
lavf demuxer (though it should work if this is exported as codec_tag).
I guess adding a pixfmt would not hurt (maybe just adding a _S behind
the normal name? I hope nobody had the idea of using signed values for
luma?), but it is not too useful without libswscale support (should not
be too hard to hack in in principle though, just do an xor 0x80008000 as
a first step or so). Reminds me that the way I do it in MPlayer is quite
suboptimal...
