I can certainly see the purple tint mplayer gives the video.

Most likely because of a bug, the conversion directly from bgr24 to any
of the yuv formats causes that color error.  I've tested on versions as
far back as 1.0pre7, and they demonstrate the same bug, so it's
certainly long-standing. 

You can convert it properly in two steps, however.  Converting from
bgr24 to rgb24, then to yuv works.  Just start your filter chain with:
    -vf scale,format=rgb24,scale,format=yv12,
