Comment (by pross):

 Steps to also produce a synthetic H.264 .wtv file. WMP/MCE seems sensitive
 to keyframe interval and can not decode yuv444p.

 {{{
 ffmpeg -f lavfi -i testsrc -f lavfi -i "sine=f=1000:d=60" -t 60 -af
 "volume=0:enable=gt(mod(t\,1)\,0.1)" \
     -pix_fmt yuv420p \
     -vcodec libx264 -x264-params keyint=25 \
     out.wtv
 }}}
