## Detailed Description

This class wraps the FLAC__StreamEncoder. If you are encoding to a file, FLAC::Encoder::File may be more convenient.

The usage of this class is similar to FLAC__StreamEncoder, except instead of providing callbacks to FLAC__stream_encoder_init*_stream(), you will inherit from this class and override the virtual callback functions with your own implementations, then call init() or init_ogg(). The rest of the calls work the same as in the C layer.

Only the write callback is mandatory. The others are optional; this class provides default implementations that do nothing. In order for some STREAMINFO and SEEKTABLE data to be written properly, you must override seek_callback() and tell_callback(); see FLAC__stream_encoder_init_stream() as to why.
