|
|
*
|
|
* \brief
|
|
* This module contains the functions which implement the file
|
|
* decoder.
|
|
*
|
|
* The basic usage of this decoder is as follows:
|
|
* - The program creates an instance of a decoder using
|
|
* OggFLAC__file_decoder_new().
|
|
* - The program overrides the default settings and sets callbacks for
|
|
* writing, error reporting, and metadata reporting using
|
|
* OggFLAC__file_decoder_set_*() functions.
|
|
* - The program initializes the instance to validate the settings and
|
|
* prepare for decoding using OggFLAC__file_decoder_init().
|
|
* - The program calls the OggFLAC__file_decoder_process_*() functions
|
|
* to decode data, which subsequently calls the callbacks.
|
|
* - The program finishes the decoding with OggFLAC__file_decoder_finish(),
|
|
* which flushes the input and output and resets the decoder to the
|
|
* uninitialized state.
|
|
* - The instance may be used again or deleted with
|
|
* OggFLAC__file_decoder_delete().
|
|
*
|
|
* The file decoder is a trivial wrapper around the
|
|
* \link oggflac_seekable_stream_decoder seekable stream decoder \endlink
|
|
* meant to simplfy the process of decoding from a standard file. The
|
|
* file decoder supplies all but the Write/Metadata/Error callbacks.
|
|
* The user needs only to provide the path to the file and the file
|
|
* decoder handles the rest.
|
|
*
|
|
* Like the seekable stream decoder, seeking is exposed through the
|
|
* OggFLAC__file_decoder_seek_absolute() method. At any point after the file
|
|
* decoder has been initialized, the user can call this function to seek to
|
|
* an exact sample within the file. Subsequently, the first time the write
|
|
* callback is called it will be passed a (possibly partial) block starting
|
|
* at that sample.
|
|
*
|
|
* The file decoder also inherits MD5 signature checking from the seekable
|
|
* stream decoder. If this is turned on before initialization,
|
|
* OggFLAC__file_decoder_finish() will report when the decoded MD5 signature
|
|
* does not match the one stored in the STREAMINFO block. MD5 checking is
|
|
* automatically turned off if there is no signature in the STREAMINFO
|
|
* block or when a seek is attempted.
|
|
*
|
|
* Make sure to read the detailed descriptions of the
|
|
* \link oggflac_seekable_stream_decoder seekable stream decoder module \endlink
|
|
* and \link oggflac_stream_decoder stream decoder module \endlink
|
|
* since the file decoder inherits much of its behavior from them.
|
|
*
|
|
* \note
|
|
* The "set" functions may only be called when the decoder is in the
|
|
* state OggFLAC__FILE_DECODER_UNINITIALIZED, i.e. after
|
|
* OggFLAC__file_decoder_new() or OggFLAC__file_decoder_finish(), but
|
|
* before OggFLAC__file_decoder_init(). If this is the case they will
|
|
* return \c true, otherwise \c false.
|
|
*
|
|
* \note
|
|
* OggFLAC__file_decoder_finish() resets all settings to the constructor
|
|
* defaults, including the callbacks.
