[MPlayer-users] yv12 output format for wmv7 ?

Hi, When I use transcode to convert WMV (wmv7) file to VCD, I found that yv12 output format is supported by avifile library. eea188:~/video/download> tcdecode -i AVSEQ03.WMV -x af6video -y yv12 > /dev/null (af6_decore.cpp) input video size: 320x240 (af6_decore.cpp) input: YVU 4:2:0 planar data If this true, is there any reason that mplayer does not support yv12 output for wmv7 codec?
