Manually construct `ogg_packet` struct instances
npm install ogg-packetnode-ogg-packet
===============
This module lets you construct your own ogg_packet struct instances using
JavaScript and Buffers. You'll most likely not need to use this module for any
practical purposes, but it is useful for testing purposes.
The more common way to get _proper_ ogg_packet structs is via a decoded OGG file
and node-ogg's ogg.Decoder class, or one of the codec's encoder classes like
node-vorbis' vorbis.Encoder class.
Installation
------------
`` bash`
$ npm install ogg-packet
Example
-------
` javascript
var ogg_packet = require('ogg-packet');
// create an ogg_packet struct instance
var packet = new ogg_packet();
// the contents of the "packet"
var buf = new Buffer('hello world');
packet.packet = buf;
packet.bytes = buf.length;
// this will be the first packet in the ogg stream
packet.b_o_s = 1;
// there will be more ogg_packets after this one in the ogg stream
packet.e_o_s = 0;
// the "granulepos" is a time-constant value used by the codec decoder
packet.granulepos = 12345;
// the "packetno" should increment by one for each packet in the ogg stream
packet.packetno = 0;
// now send the packet off to an ogg.Encoder orvorbis.Decoder
// a codec-specific decoder like ...`
stream.packetin(packet.buffer, function (err) { / ... / });
API
---
A ref-struct class that mirrors the ogg_packet fields in the ogg.h file.
` c``
typedef struct {
unsigned char *packet;
long bytes;
long b_o_s;
long e_o_s;
ogg_int64_t granulepos;
ogg_int64_t packetno;
} ogg_packet;
