Thanks for the suggestion! I just tried this and I'm seeing some serious weirdness with -vo jpeg: $ rm *.jpg $ mplayer -vo jpeg ../input.avi -endpos 10 [snip] VIDEO: [FMP4] 720x384 24bpp 29.970 fps 1438.3 kbps (175.6 kbyte/s) A: 10.0 V: 10.0 A-V: 0.000 ct: -0.000 301/301 5% 48% 0.6% 0 0 $ ls *.jpg | wc -l 244 So ten seconds at 29.97fps results in 301 frames played but only 244 saved to disk? What am I missing here?
