|

|
|
* \brief
|
||
|
|
* This module contains the functions which implement the file
|
||
|
|
* encoder.
|
||
|
|
*
|
||
|
|
* The basic usage of this encoder is as follows:
|
||
|
|
* - The program creates an instance of an encoder using
|
||
|
|
* FLAC__file_encoder_new().
|
||
|
|
* - The program overrides the default settings using
|
||
|
|
* FLAC__file_encoder_set_*() functions.
|
||
|
|
* - The program initializes the instance to validate the settings and
|
||
|
|
* prepare for encoding using FLAC__file_encoder_init().
|
||
|
|
* - The program calls FLAC__file_encoder_process() or
|
||
|
|
* FLAC__file_encoder_process_interleaved() to encode data, which
|
||
|
|
* subsequently writes data to the output file.
|
||
|
|
* - The program finishes the encoding with FLAC__file_encoder_finish(),
|
||
|
|
* which causes the encoder to encode any data still in its input pipe,
|
||
|
|
* rewind and write the STREAMINFO metadata to file, and finally reset
|
||
|
|
* the encoder to the uninitialized state.
|
||
|
|
* - The instance may be used again or deleted with
|
||
|
|
* FLAC__file_encoder_delete().
|
||
|
|
*
|
||
|
|
* The file encoder is a wrapper around the
|
||
|
|
* \link flac_seekable_stream_encoder seekable stream encoder \endlink which supplies all
|
||
|
|
* callbacks internally; the user need specify only the filename.
|
||
|
|
*
|
||
|
|
* Make sure to read the detailed description of the
|
||
|
|
* \link flac_seekable_stream_encoder seekable stream encoder module \endlink since the
|
||
|
|
* \link flac_stream_encoder stream encoder module \endlink since the
|
||
|
|
* file encoder inherits much of its behavior from them.
|
||
|
|
*
|
||
|
|
* \note
|
||
|
|
* The "set" functions may only be called when the encoder is in the
|
||
|
|
* state FLAC__FILE_ENCODER_UNINITIALIZED, i.e. after
|
||
|
|
* FLAC__file_encoder_new() or FLAC__file_encoder_finish(), but
|
||
|
|
* before FLAC__file_encoder_init(). If this is the case they will
|
||
|
|
* return \c true, otherwise \c false.
|
||
|
|
*
|
||
|
|
* \note
|
||
|
|
* FLAC__file_encoder_finish() resets all settings to the constructor
|
||
|
|
* defaults.
