VDec: vo config request - 200 x 80 (preferred csp: BGR 15-bit)
Trying filter chain: vo
vo_debug: query(BGR 8-bit) returned 0x0 (i=0)
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
SwScale params: -1 x -1 (-1=no scaling)

The selected video_out device is incompatible with this codec.

Looks like the video is configured for paletted bgr8 anyway, did you
added BGR15 to out line in codecs.conf in fffli section? If not,
replace the current "out BGR8" with "out BGR15,BGR8 query" to tell
MPlayer that the codec have two possible output format (BGR15 and
BGR8), but only one of them is supported for a specific file (query).

If that's not the problem, try the codec also on ffplay to exclude any
problem with MPlayer code, else post more details.

btw i strongly suggest you to use cvs version of ffmpeg and mplayer to
develope, expecially if you're using and64 as suggested by your output.

Ciao,
