libogg - General Functions

# General Functions

Libogg contains several functions which are generally useful when using Ogg streaming, whether encoding or decoding.

All the libogg specific functions are declared in "ogg/ogg.h".

These functions can be used to manipulate some of the basic elements of Ogg - streams and pages. Streams and pages are important during both the encode and decode process.

function | purpose
ogg_stream_init | Initializes an Ogg bitstream.
ogg_stream_clear | Clears the storage within the Ogg stream, but does not free the stream itself. |
ogg_stream_reset | Resets the stream status to its initial position.
ogg_stream_destroy | Frees the entire Ogg stream.
ogg_stream_check | Check for asynchronous errors.
ogg_stream_eos | Indicates whether we are at the end of the stream.
ogg_page_version | Returns the version of ogg_page that this stream/page uses
ogg_page_continued | Indicates if the current page contains a continued packet from the last page.
ogg_page_packets | Indicates the number of packets contained in a page.
ogg_page_bos | Indicates if the current page is the beginning of the stream.
ogg_page_eos | Indicates if the current page is the end of the stream.
ogg_page_granulepos | Returns the precise playback location of this page.
ogg_page_serialno | Returns the unique serial number of the logical bitstream associated with this page.
ogg_page_pageno | Returns the sequential page number for this page.
ogg_packet_clear | Clears the ogg_packet structure.
ogg_page_checksum_set | Checksums an ogg_page.
