...roblem? IMHO it's better to move setvbuf() out of libFLAC/stream_encoder.c into flac/encode.c. I can see two ways to do this: 1) Add a new function to libFLAC API that have access to encoder->private_->file and can call setvbuf: FLAC_API FLAC__bool FLAC__stream_encoder_set_buffer_size(FLAC__StreamEncoder *encoder, unsigned size); 2) Rewrite EncoderSession_init_encoder() in flac/encode.c so that it opens the file, calls setvbuf and then uses FLAC__stream_encoder_init[_ogg]_stream() instead of FLAC__stream_encoder_init[_ogg]_file(). It's more difficult, but doesn't require API change.

FYI, I have checked in a few interesting things. One is a speedup to the decoder (about 15% improvement in overall decode time). Another is a new interface to FLAC file metadata. If you're curious look at include/FLAC/metadata.h. It is basically a collection of object manipulation routines and iterators that make it pretty easy to add/edit/delete FLAC metadata in files efficiently. The

Great. Then I'll take a crawl into the sources... Thanks for this first pointer

What small device do you have in mind? The smallest device I could possibly imagine *encoding* FLAC on is Rasberry Pi which has 512Meg of RAM.

Hello all, I've been writing a basic encoder using libFLAC++. It seems to work fine, as in the resultant file is playable in any FLAC compatible player, however the compression ratio is very small - the main example being a 60MB file compressing to 54MB, i guess there's an option i've missed, but i cannot track it down. I was hoping someone could point it out for me:
