Well, after a lot more reading (and probably because I was looking at
the Ubuntu sources before) I've come to the conclusion that that's
what avcodec_decode_audio3() already does.

In other words, it looks like int16_t *samples is a ruse. If
avctx->sample_fmt is SAMPLE_FMT_FLT, you can just do:

  float data[32];
  avcodec_decode_audio3( avctx, (short *) data, sizeof(data), packet );

The next question is, is that intended?
