How to capture still images from video using mencoder?

[kkol123]

does anyone know how to capture a batch of still images from video using mencoder?
what is the command that can do that?
i can always use ffmpeg on most of video files,but ffmpeg does not support rmvb so i need to use mencoder for this matter
since i'm not familiar with mencoder,i need help from you guys

Try mplayer with -vo jpeg

mplayer -vo jpeg <video file> and mplayer -vo png <video file> output
video into jpeg and png files respectively.

-osdlevel 0 suppreses volume + seek from appearing in the images

-sstep <sec>
Specifies seconds between displayed frames. Useful for slideshows.

-ss <time> (see -sb option too)
Seek to given time position.

EXAMPLE:
-ss 56 seeks to 56 seconds
-ss 01:10:00 seeks to 1 hour 10 min

-frames <number>
Play/convert only first <number> frames, then quit.

if someone found a win32 build of ffmpeg that supports rmvb,please tell me too
i always prefer ffmpeg over mencoder

does mplayer support rmvb without the codec files?

mencoder = mplayer.
