node-dvbtee

node-dvbtee is an MPEG2 transport stream parser addon for Node.js

Any standard MPEG2TS stream is supported, with additional specific support for broadcast television transport streams containing PSIP tables and descriptors.

These tables and descriptors contain information about the stream, such as broadcast info, program info, and electronic program guide (EPG).

Installation

$ npm install dvbtee

Example

var dvbtee = require('dvbtee')

var parser = new dvbtee.Parser

parser.on('data', function(data) {
  console.log('table id: ' + data.tableId,
              '\ntable name: ' + data.tableName,
              '\ntable data:\n', JSON.stringify(data, null, 2))
})

// on a stream:
fs.createReadStream('sample1.ts').pipe(parser)

// on a buffer:
fs.readFile('sample2.ts', function(err, buf) {

    parser.feed(buf, buf.length, function(err, status) {

      if (err)
          console.log(err)
      else
          console.log('complete: status = ' + status)

    })
})

Pass-Thru Mode Example

var dvbtee = require('dvbtee')

var parser = new dvbtee.Parser({ 'passThru': true })

parser.on('psip', function(data) {
  console.log('table id: ' + data.tableId,
              '\ntable name: ' + data.tableName,
              '\ntable data:\n', JSON.stringify(data, null, 2))
})

// on a stream in pass-thru mode:
fs.createReadStream('sample3.ts').pipe(parser).pipe(fs.createWriteStream('outfile.ts'))
