But first a question -- is the zero on the right dropped frames? A:78179.1 V:78179.1 A-V: 0.004 ct: 0.073 53306/53306 17% 79% 1.6% 44608 0 I ask, of course, because I found none. mplayer -noconfig all foo.mp2 dropped 0 top cpu/mem 58.6 1.7 audio leads mplayer -noconfig all -demuxer lavf foo.mp2 dropped 0 top cpu/mem 68.6 1.5 audio leads (worse) mplayer -noconfig all -vc ffmpeg12 -vo vdpau foo.mp2 dropped 0 top cpu/mem 63.9 1.7 audio leads (worse) mplayer -noconfig all -vc ffmpeg2 -vo vdpau foo.mp2 dropped 0 top cpu/mem 59.3 1.6 audio leads (worse) mplayer -noconfig all -ao alsa::device=hw=0.3 -vc ffmpeg2 -vo vdpau foo.mp2 dropped 0 top cpu/mem 28.3 1.4 (yes, really) audio leads First and last were the best, though not great.
