Hmmm ... The omission (and other stuff) was the result of confusion on
my part. Retest. Results here are from playing a 5 minute clip to the

an order-of-magnitude CPU %. Dropped numbers are from the last status

mplayer -noconfig all foo.mp2
dropped 4054
top 60
mplayer -noconfig all -demuxer lavf foo.mp2
dropped 4119
top 60
mplayer -noconfig all -vc ffmpeg12vdpau foo.mp2
dropped 4072
top 40
mplayer -noconfig all -ao alsa::device=hw=0.3 -vc ffmpeg2 -vo vdpau
foo.mp2
dropped 2215
