input formats

N-channel input

Set it to either

I think the first sentence is completely redundant.  The following
should do as well:

  If the input channel number is less than <minchn>, the filter will
  detach itself (default: 5).

audio filter for runtime AC-3 encoding with libavcodec

There are some awfully long lines in there.  Keeping them below 80
characters would be a plus.
