[MPlayer-dev-eng] RGB24 <-> BGR24

[Arpi]

Hi,

Michael, could you implement a fast 24bpp RGB<->BGR converter ?
There is a 32bpp one, but in most cases we need 24bpp, and the
current  24to32 -> rgbtobgr -> 32to24 is a way silly and slow

also, what about rgb24->yuy2 ?
rgb24->yv12->yuy2 is possible, but it's slower and produces worse quality.

hmm. and what about a yuv422p -> yuy2 converter?
yuv422p is similar to yv12, but u,v ar eonly horizontally downscaled,
the height of u,v is teh same as y
the current way, i use, multiply u/v stride by 2, and handle it as yv12
image, but it may produce worse quality. yuv422p is produced by libavcodec,
for yuv 4:2:2 forrmats (mostly mjpeg)
