I understand your frustration, but with the current API you
have to translate FLAC__STREAM_ENCODER_NOT_STREAMABLE into:
1. blocksize must be one of 192,576,1152,2304,4608,256,512,
   1024,2048,4096,8192,16384,32768
2. sample rate must be one of 8000,16000,22050,24000,32000,
   44100,48000,96000
3. bits-per-sample must be one of 8,12,16,20,24

yes.  spam is a big problem so I think stuff that gets tagged
is diverted for approval (I haven't exercised moderator power on
the Xiph lists yet).  I haven't seen any mails get lost (maybe
resends/duplicates that are cued up get deleted) but sometimes
they do get delayed a couple of days.
