Comment (by ami_stuff):

 more samples

 maybe the problem have something to do with:

 aiffdec.c:
 {{{
     if (version != AIFF_C_VERSION1 || codec->codec_id ==
 CODEC_ID_PCM_S16BE) {
         codec->codec_id = aiff_codec_get_id(codec->bits_per_coded_sample);
         codec->bits_per_coded_sample =
 av_get_bits_per_sample(codec->codec_id);
         aiff->block_duration = 1;
     } else {
         switch (codec->codec_id) {
         case CODEC_ID_PCM_F32BE:
         case CODEC_ID_PCM_F64BE:
         case CODEC_ID_PCM_S16LE:
         case CODEC_ID_PCM_ALAW:
         case CODEC_ID_PCM_MULAW:
             aiff->block_duration = 1;
             break;
         case CODEC_ID_ADPCM_IMA_QT:
             codec->block_align = 34*codec->channels;
             break;
         case CODEC_ID_MACE3:
             codec->block_align = 2*codec->channels;
             break;
         case CODEC_ID_MACE6:
             codec->block_align = 1*codec->channels;
             break;
         case CODEC_ID_GSM:
             codec->block_align = 33;
             break;
         case CODEC_ID_QCELP:
             codec->block_align = 35;
             break;
         default:
             aiff->block_duration = 1;
             break;
         }
         if (codec->block_align > 0)
             aiff->block_duration = av_get_audio_frame_duration(codec,

 }}}
