[MEncoder-users] possible to use -af scaletempo with mencoder?

[Paul Ivanov]

is it possible to encode video with the scaletempo plugin? I can play 
videos at twice the speed with reasonable audio (no chipmunk sounds) using:

mplayer  -af scaletempo -speed 2


but
mencoder -af scaletempo -speed 2

just ignores the -af scaletempo option (audio and video are twice the 
speed, but higher pitch)

thanks
