oggstreamstate

OggStreamState is a data structure used in the Ogg multimedia container format, which is designed for multiplexing various types of data streams, such as audio, video, and text, into a single file. The OggStreamState structure is part of the libogg library, which provides functions for creating, reading, and manipulating Ogg streams.

The OggStreamState structure contains information about a specific Ogg stream, including its serial number, which uniquely identifies the stream within the Ogg container. It also keeps track of the current page sequence number and the granule position, which indicates the position within the stream's timeline. Additionally, the structure maintains a buffer for storing Ogg packets, which are the basic units of data in an Ogg stream.

The OggStreamState structure is used in conjunction with other libogg functions to perform tasks such as initializing a new stream, adding packets to the stream, and flushing the stream to create Ogg pages. These pages are then written to an Ogg container file, allowing for the efficient storage and playback of multiplexed media streams.

In summary, OggStreamState is a crucial component of the libogg library, enabling the creation and manipulation of Ogg streams within the Ogg multimedia container format. Its role is essential for the efficient storage and playback of multiplexed media data.
