From the manpage:

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

So, with a 25fps source file, -frames 125 plays/converts five seconds.

Better use -vo png or -vo pnm (the last one is only available in CVS) to 
avoid having additional JPEG artifacts added.
