Struct ogg::reading::BasePacketReader

pub struct BasePacketReader { /* fields omitted */ }

Low level struct for reading from an Ogg stream.

Note that most times you'll want the higher level PacketReader struct.

It takes care of most of the internal parsing and logic, you will only have to take care of handing over your data.

Essentially, it manages a cache of package data for each logical bitstream, and when the cache of every logical bistream is empty, it asks for a fresh page. You will then need to feed the struct one via the push_page function.

All functions on this struct are async ready. They get their data fed, instead of calling and blocking in order to get it.

Methods

impl BasePacketReader

pub fn new() -> Self

Constructs a new blank BasePacketReader.

You can feed it data using the push_page function, and obtain data using the read_packet function.

pub fn read_packet(&mut self) -> Option<Packet>

Extracts a packet from the cache, if the cache contains valid packet data, otherwise it returns None.

If this function returns None, you'll need to add a page to the cache by using the push_page function.

pub fn push_page(&mut self, page: OggPage) -> Result<(), OggReadError>

Pushes a given Ogg page, updating the internal structures with its contents.

If you want the code to function properly, you should first call parse_segments, then parse_packet_data on a PageParser before passing the resulting OggPage to this function.

pub fn update_after_seek(&mut self)

Reset the internal state after a seek

It flushes the cache so that no partial data is left inside. It also tells the parsing logic to expect little inconsistencies due to the read position not being at the start.
