hypercore-video-segmenter

Store live streaming video segments using hypercore.

npm install hypercore-video-segmenter

Usage

var segmenter = require('hypercore-video-segmenter')
var s = segmenter(someHypercore)

var ws = s.createSegmentWriteStream({
  duration: 10 // duration in seconds
}, function (err) {
  console.log('video segment added')
  s.get(0, console.log) // prints metadata of the first segment
})

var rs = fs.createReadStream('next-segment.ts')

rs.pipe(ws)

API

var s = segmenter(core, [key])

Create a new segmenter. If you want to replicate another segmenter pass a key.

s.key

The replication key verifying the data of the segmenter. Pass that to another segmenter, and connect it using replication streams to start replicating the data.

s.discoveryKey

A key that be used to discover similar segmenters, but that doesn't allow other people to download the data.

var ws = s.createSegmentWriteStream(options, [callback])

Write a new segment. You should specify how long this segment is in seconds in the options map using the duration key.

var rs = s.createSegmentReadStream(seq)

Create a read stream that returns segment data. seq is the segment index you want to read.

s.get(seq, callback)

Get metadata about a segment. seq is the segment index you want info about. Returns an object looking like this

{
  seq: seq,
  duration: durationInSeconds
  length: byteLength
}

s.getLatest(n, callback)

Get the latest n segment metadata objects. Useful for generating a playlist.

s.getNext(callback)

Get the next segment metadata.

var stream = s.replicate()

Create a replication stream that replicates the data in the segmenter. You should pipe this to another segmenter.
