I did check what happens. First vd_ffmpeg.c maps the colorspace
PIX_FMT_PAL8 to IMGFMT_BGR8 (this must break the colors). Then the
format filter tries a conversion BGR8->RGB32. sws_getContext() uses
rgb2rgbWrapper for all RGB->RGB conversions which do not need dithering,
but rgb2rgbWrapper only supports 15,16,24 and 32 bit cases. When it's
called with RGB8->RGB32 it prints an error and then calls a function
pointer left at NULL.
