libavcodec/zmbvenc: Add support for RGB formats
This consists mostly of the following changes:
- add newly supported pixel formats (RGB555LE, RGB565LE, BGR0)
- select the ZMBV format (c->fmt) and bytes per pixel (c->bypp) based on
avctx->pix_fmt
- multiply widths/x-values by c->bypp, in places where bytes, not pixels, are
expected
- disable palette-writing code for non-palette pix_fmts
- make a note about histogram[]'s datatype (it could need increasing if
ZMBV_BLOCK is increased)
- adjust the c->score_tab length to take up to (and including) 4 times the
number of pixels in a block
- initialise c->score_tab up to c->bypp * the number of pixels
Note: the ZmbvFormat enum allows for additional bit depths:
- 1,2,4-bit (palette)
- 24-bit (RGB)
At time of writing the specifics of these (e.g. channel order, bit alignment)
are not currently defined, and DOSBox only implements support for 8/15/16/32
bpp.
One might expect the 24-bit format - if implemented - to be BGR24, to have the
same channel order as BGR0.
However, the decoder in zmbv.c has been guessed to use RGB24, so I have chosen
to not contradict this, and omitted specific support for this format.
