    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).

    NPM

    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'))
