[MPlayer-users] Bug? AVS source not reporting YUY2 file correctly?

[Nicolas Hesler]

When supplying a YUY2 source (ffhuffyuv file) served from an AVISynth 
script, mplayer reports/detects that the file is RAW YV12 instead of 
YUY2.  ffmpeg reports correctly for both the original video as source 
and the avs script.  Mplayer (last example) reports the avs script as 
RAW YV12.
