Hi Edgar,

both mplayer and VLC provide such controls, it allows to slow
down or speed up the video but the audio is not pitch corrected as far
as I can tell.

A line like this works but requires to set the pitch beforehand
and also sounds rather bad.
mplayer -speed 0.5 -af ladspa=tap_pitch:tap_pitch:0:100:-90:0 Careless\
