ffenc_nellymoser lists many different audio formats in their sink caps:

  SINK template: 'sink'
    Availability: Always
    Capabilities:
      audio/x-raw-int
               channels: [ 1, 2 ]
                   rate: [ 4000, 96000 ]
                 signed: true
             endianness: 1234
                  width: 16
                  depth: 16
      audio/x-raw-int
               channels: [ 1, 2 ]
                   rate: [ 4000, 96000 ]
                 signed: true
             endianness: 1234
                  width: 32
                  depth: 32
      audio/x-raw-float
               channels: [ 1, 2 ]
                   rate: [ 4000, 96000 ]
             endianness: 1234
                  width: 32
      audio/x-raw-float
               channels: [ 1, 2 ]
                   rate: [ 4000, 96000 ]
             endianness: 1234
                  width: 64

Despite this, the encoders only work properly when actually fed with
audio/x-raw-int, width=16 - feeding data in any other format only produces
garbage, without outputting any warning.

Sample command line that illustrates the problem:
gst-launch audiotestsrc ! audio/x-raw-float ! ffenc_nellymoser !
ffdec_nellymoser ! wavenc ! filesink location=foo.wav

The same issue, listing too many sink caps, seems to happen for at least
ffenc_alac, too.
