Manually construct ogg_packet struct instances


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.

$ npm install ogg-packet
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_packet`s 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` or 
// a codec-specific decoder like `vorbis.Decoder`... 

A ref-struct class that mirrors the ogg_packet fields in the ogg.h file.

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;
