[MPlayer-G2-dev] MID proposal

Let's see the actual cases:
0: yuv
1: rgb
2: mpeg
3: mjpeg
further types (cmyk :D)

Or what about adding a 'compressed' type that would indicate
mpeg1/mjpeg/mpeg4/asv2 (you know, asus cards can en/decode asv) and
others.

What about naming them cr_h/v (chroma horizontal / vertical)

Or the flags field from mpi: (i forgot it first :)
MPI_IMGFLAG_PLANAR, YUV, SWAPPED, RGB_PALETTE

Or what about merging flags with type?

probably it has not much sense (i can see only one, if you read the
thread about jpeg_enc)

but without big changes it will become the same bloat as g1 after some
time

A new idea: the new swscaler should based on a similar structure.

And also we could make a mid_to_imgfmt function, so we could really get
rid of internal imgfmt usage, only some filters/modules/whatever which
need to convert to the ancient format could use it.
