This module describes porting from FLAC 1.4.3 to FLAC 1.5.0.

Summary

Between FLAC 1.4.3 and FLAC 1.5.0, there have been changes to existing C functions and enums:

• the functions FLAC__metadata_get_streaminfo, FLAC__metadata_get_tags and FLAC__metadata_get_cuesheet can now read from Ogg FLAC files
• when encoding Ogg FLAC files, the 'samples' argument of the write callback no longer always returns 0.
• two error statuses have been added to the FLAC__StreamDecoderErrorStatus enum
• one status is added to FLAC__StreamDecoderState, which is only used when the new decoding of chained streams functionality is enabled
• one status is added to FLAC__StreamDecoderReadStatus, which is only used when the new decoding of chained streams functionality is enabled
• the function FLAC__metadata_chain_write_with_callbacks_and_tempfile can now be used regardless of whether a tempfile is actually needed, which is useful when writing to a new file is desired anyway

Furthermore, there have been the following additions:

• the functions FLAC__stream_decoder_set_decode_chained_stream, FLAC__stream_decoder_get_decode_chained_stream, FLAC__stream_decoder_finish_link, FLAC__stream_decoder_skip_single_link, FLAC__stream_decoder_process_until_end_of_link and FLAC__stream_decoder_get_link_lengths have been added to support decoding of chained streams
• the function FLAC__metadata_chain_write_new_file has been added, which is useful to combine copying of a file with changing its metadata
• the function FLAC__stream_decoder_find_total_samples was added, which seeks to the end of a file to find the total number of samples
• the function FLAC__stream_encoder_set_num_threads and FLAC__stream_encoder_get_num_threads have been added, which can be used to enable multithreading in the encoder

For the C++ API, changes are the same, but in C++ nomenclature
