[MPlayer-users] slave mode commands: speed_xxx - bug (when using together with -af equalizer)

Please don't make assumptions on what is redundant and what is not and
simply attach the whole output!

This is caused by an integer overflow. The attached patch should fix it,
although it could use some improvement.
But the equalizer filter still breaks when after decreasing the speed
too much and then reincreasing it again. :-(
