Some suggestions

Try adding a new file:

- node.files.add(new node.types.Buffer('Hello world!'), (err, res) => { - if (err || !res) { + node.files.add(new node.types.Buffer('Hello world!'), (err, filesAdded) => { + if (err) { return console.error('Error - ipfs files add', err, res) } - res.forEach((file) => console.log('successfully stored', file)) + filesAdded.forEach((file) => console.log('successfully stored', file.hash)) })

You can cat that same file. If you used the exact same string as above ('Hello world!') you should have an hash like this: 'QmQzCQn4puG4qu8PVysxZmscmQ5vT1ZXpqo7f58Uh9QfyY'

One of the advantages of HLS over some other streaming technologies is that the content can be hosted on a plain old web server without any special server-side support. The way this works is that the original content (the stream or video/audio file) is split up into small MPEG2-TS segments before being uploaded to the server. The segments are then fetched by the HLS player on the fly (using regular HTTP GET requests) and get spliced together to a continuous stream. @@ -12,6 +13,7 @@ In addition to the segments there are also so-called manifests (m3u8 files) whic The fact that HLS content is just "a bunch of files" makes it a good choice for IPFS (another protocol that works this way is MPEG-DASH, which could certainly be a good choice as well). Furthermore, the [hls.js](https://github.com/video-dev/hls.js) library enables straightforward integration with the HTML5 video element. ## hlsjs-ipfs-loader + The hls.js library ships with an HTTP based content loader only, but it's fortunately possible to configure custom content loaders as well, which is what makes IPFS streaming possible in this case. A loader implementation that fetches content using js-ipfs can be found [here](https://www.npmjs.com/package/hlsjs-ipfs-loader), and is easy to use on a regular HTML page: ```html @@ -21,6 +23,7 @@ The hls.js library ships with an HTTP based content loader only, but it's fortun ``` ## Generating HLS content + In order for any of the above to be useful, we also need to have a way to actually generate HLS manifests and MPEG2-TS segments from an arbitrary video/audio file. Luckily, most new builds of `ffmpeg` are compiled with this capability. For example, say we have a directory containing a video file `BigBuckBunny_320x180.mp4`. We can then create a sub directory and generate the HLS data there, and finally add it to IPFS: diff --git a/examples/browser-video-streaming/streaming.js b/examples/browser-video-streaming/streaming.js index 21c1f706b3..2cb915adcc 100644 --- a/examples/browser-video-streaming/streaming.js +++ b/examples/browser-video-streaming/streaming.js @@ -5,30 +5,18 @@ const testhash = 'QmdpAidwAsBGptFB3b6A9Pyi5coEbgjHrL3K2Qrsutmj9K' const repoPath = 'ipfs-' + Math.random() -const ipfs = new Ipfs({ - init: false, - start: false, - repo: repoPath -}) +const node = new Ipfs({ repo: repoPath }) -ipfs.init((err) => { - if (err) { - throw err +node.on('ready', () => { + Hls.DefaultConfig.loader = HlsjsIpfsLoader + Hls.DefaultConfig.debug = false + if (Hls.isSupported()) { + const video = document.getElementById('video') + const hls = new Hls() + hls.config.ipfs = node + hls.config.ipfsHash = testhash + hls.loadSource('master.m3u8') + hls.attachMedia(video) + hls.on(Hls.Events.MANIFEST_PARSED, () => video.play()) } - - ipfs.start(() => { - Hls.DefaultConfig.loader = HlsjsIpfsLoader - Hls.DefaultConfig.debug = false - if (Hls.isSupported()) { - const video = document.getElementById('video') - const hls = new Hls() - hls.config.ipfs = ipfs - hls.config.ipfsHash = testhash - hls.loadSource('master.m3u8') - hls.attachMedia(video) - hls.on(Hls.Events.MANIFEST_PARSED, () => { - video.play() - }) - } - }) }) diff --git a/examples/browser-webpack/src/components/app.js b/examples/browser-webpack/src/components/app.js index 7e6b273643..e1e4cbff82 100644 --- a/examples/browser-webpack/src/components/app.js +++ b/examples/browser-webpack/src/components/app.js @@ -25,11 +25,9 @@ class App extends React.Component { function create () { // Create the IPFS node instance - node = new IPFS({ - repo: String(Math.random() + Date.now()) - }) + node = new IPFS({ repo: String(Math.random() + Date.now()) }) - node.on('ready', () => { + node.once('ready', () => { console.log('IPFS node is ready') ops() }) @@ -47,25 +45,15 @@ class App extends React.Component { }) }) - node.files.add([Buffer.from(stringToUse)], (err, res) => { - if (err) { - throw err - } + node.files.add([Buffer.from(stringToUse)], (err, filesAdded) => { + if (err) { throw err } - const hash = res[0].hash + const hash = filesAdded[0].hash self.setState({added_file_hash: hash}) - node.files.cat(hash, (err, res) => { - if (err) { - throw err - } - let data = '' - res.on('data', (d) => { - data = data + d - }) - res.on('end', () => { - self.setState({added_file_contents: data}) - }) + node.files.cat(hash, (err, data) => { + if (err) { throw err } + self.setState({added_file_contents: data}) }) }) } diff --git a/examples/exchange-files-in-browser/package.json b/examples/exchange-files-in-browser/package.json index 84ea13b2a4..6fa24583b8 100644 --- a/examples/exchange-files-in-browser/package.json +++ b/examples/exchange-files-in-browser/package.json @@ -3,8 +3,8 @@ "version": "0.0.0", "scripts": { "bundle": "browserify public/js/app.js > public/js/bundle.js", - "serve": "http-server -c-1 -p 12345 public", - "start": "npm run bundle && npm run serve" + "dev": "npm run bundle && npm run start", + "start": "http-server -c-1 -p 12345 public" }, "license": "MIT", "devDependencies": { diff --git a/examples/exchange-files-in-browser/public/index.html b/examples/exchange-files-in-browser/public/index.html index 7b4da10591..6602f7c52e 100644 --- a/examples/exchange-files-in-browser/public/index.html +++ b/examples/exchange-files-in-browser/public/index.html @@ -62,7 +62,7 @@
