[MPlayer-dev-eng] SN40 Codec

We need to transcode video files with a fourcc of "SN40".  I tried to
create a videocodec block for it, but couldn't quite get it right.
Since win32-codec-howto.txt recommends mailing this list, I am doing so.

Here's the vital info:
    fourcc: SN40
    GUID: 2D822FE8-9F32-4558-84C8-9E0C6DD768A0
    Codec: http://www.verint.com/video_solutions/misc/VerintVideoSolutionsCodecs_RU3.1.zip
    Sample movie: http://brianhv.org/temp/sn40sample.avi

This is the closest I got to a working videocodec block, though some of
the options (especially "out") I was guessing at blindly.

release 20090304

videocodec sn40
  info "LrxTextOV"
  status untested
  fourcc SN40
  driver vfw
  dll "SN4Codec.dll"
  ;guid 0x2D822FE8, 0x9F32, 0x4558, 0x84, 0xC8, 0x9E, 0x0C, 0x6D, 0xD7, 0x68, 0xA0
  ;format 0x30344E53
  out BGR24

When trying to view the file in mplayer with the above in my
codecs.conf, I see a green window and the following message in my
command prompt many times:

Error decompressing frame, err=-2

Thanks in advance for any help.
