[MPlayer-users] converted video is shorter

[Dave Wayne]

I'm trying to convert another quicktime movie to flash, but mencoder keeps
shortening the video.

I've tried a variety of options, the ones below are to prevent any frames
from being dropped but its still shorter.

Mplayer plays the movie for the proper duration of ~55s. mencoder comes in
at ~19s

 /usr/local/bin/mencoder src_file  -ovc lavc  -oac mp3lame  -o dest_file.flv
-ni -mc 0 -noskip
