[MPlayer-users] MPlayer with Pitch Shift

[Nan Null]

I decided to go using another route.  So far it works, but I haven't tried with the problematic files yet.  I think it should work too.

This time, I am able to over come the multi-track problem too, which is great.

Here's how I do it: use alsa and is configuration file.

The configuration file (in ~/.asoundrc)

pcm.ladspa {
  type ladspa
  slave.pcm "plughw:0,0";
  path "/usr/lib/ladspa";
  plugins [
    {
      label tap_pitch
      input {
        controls [ 0 0 -90 0]
      }
    }
 ]
}

pcm.!default {
  type plug
  slave.pcm "ladspa"
}

And the mplayer command:

mplayer -ao alsa  somefile.mpg

The problem I encounter here is that I always have to use the default block.  If I delete it, and specify the device directly:

mplayer -ao alsa,device=ladspa somefile.mpg

It won't work.  Could someone please point out why so?  Thanks.
