[MPlayer-dev-eng] Re: [Dxr3-devel] dxr3 as a generic framebuffer :D (fwd)

[David Holm]

Ok,
this is something I've never heard of, but I will definately try it out 
(right away).
Thanks

A question about dshow/vfm codecs, as I get it I need to either use 
BGR24 (who the hell came up with BGR? I wanna kick his ass) or do a 
conversion from YUY2 (which I believe would be much slower). Also I'm 
assuming all win32 codecs use draw_frame and linux one's uses 
draw_slice? Anyhow, draw_frame( uint8 *src[] ) for a BGR24 returned from 
a win32 codec, are they encoded like src[B] = malloc(w*h) src[G] = 
malloc(....) or src[0] = malloc (w*h*3) ?
I'm getting segfaults when trying to use libavcodec to mpeg encode these...
