FLAC  1.3.1
Porting from FLAC 1.1.4 to 1.2.0

This module describes porting from FLAC 1.1.4 to FLAC 1.2.0.

There were only very minor changes to the interfaces from 1.1.4 to 1.2.0. In libFLAC, FLAC__format_sample_rate_is_subset() was added. In libFLAC++, FLAC::Decoder::Stream::get_decode_position() was added.

Finally, value of the constant FLAC__FRAME_HEADER_RESERVED_LEN has changed to reflect the conversion of one of the reserved bits into active use. It used to be 2 and now is 1. However the FLAC frame header length has not changed, so to skip the proper number of bits, use FLAC__FRAME_HEADER_RESERVED_LEN + FLAC__FRAME_HEADER_BLOCKING_STRATEGY_LEN
