[MPlayer-dev-eng] -format option obsolete?

[Diego Biurrun]

Hi!

I'm in the (tedious) process of updating the audio filter
documentation and noticed that the -format option is wrong now:

-format <0-8192>
  Select the format used for output from the filter layer
  (according to the defines in libao2/afmt.h):
        1 Mu-Law
        2 A-Law
        4 Ima-ADPCM
        8 unsigned 8-bit
       16 signed 16-bit (little-endian)
       32 signed 16-bit (big-endian)
       64 signed 8-bit
      128 unsigned 16-bit (little-endian)
      256 unsigned 16-bit (big-endian)
      512 MPEG (2) Audio
     1024 AC3
     4096 signed 32-bit (little-endian)
     8192 signed 32-bit (big-endian)

libao2/afmt.h was removed and supplanted by libaf/af_format.h I
think.  However, I'm too lame to make much sense out of that file..

What's the point of -format anyway?  How does it differ from the
format audio filter?
