[MPlayer-dev-eng] [PATCH] HuffYUV native support

[Roberto Togni]

Hi all.

These patches add HuffYUV native support to Mplayer for YUV and RGB 
files (RGBA not supported yet).

Output format is YUY2 or BGR32,BGR24, and is selected in init function 
because frame format is not known at demuxer. This portion does not 
work correctly: some vo (es. sdl) select YUV, other (es. x11) RGB, 
ignoring my request made by mpcodecs_config_vo.
This is the code fragment:

switch (hc->bitmaptype) {
  case BMPTYPE_YUV:
   vo_ret = mpcodecs_config_vo(sh,sh->disp_w,sh->disp_h,IMGFMT_YUY2);
   break;
  case BMPTYPE_RGB:
   vo_ret = mpcodecs_config_vo(sh,sh->disp_w,sh->disp_h,IMGFMT_BGR24);
   break;
}

Is output format selection by mpcodecs already implemented?

I also had to disable MP_IMAGEFLAG_ACCEPT_STRIDE for BGR32/BGR24 output 
because it wasn't working, i'm still looking at it.

I uploaded some samples in different formats to incoming/HuffYUV. The 
codec plays ok also huffyuv_segfault.avi and cons_huffyuv.avi from the 
samples directory on ftp. I did not downloaded the 22Mb file.

If you have questions/problems contact me.

Ciao,
  Roberto
