that looks fine. I don't think it's the compression level setting.
try without calling that function at all, the encoder will default
to compression level 0, which should still give some compression.
usually the problem is in the way the samples are formatted and
passed to FLAC__stream_encoder_process(). I'd have to see that
code to debug. see also
