Couldn't open codec flac, br=224.

In tracing through the code, it appears that problem is that
sample_fmt != SAMPLE_FMT_S16 (as seen in flac_encode_init()).  Matter
of fact, sample_fmt == SAMPLE_FMT_NONE.

It seems to come into existence initialized that way and then never
set to something else.

Something wrong with my set up, or am I missing something?
