• Is there any way to stream video while encoding except using ffmpeg ?

  25 novembre 2016, par Ruslan Doronichev

  I am developing a cloud service, that allow users to upload video files from torrents and watch them online. In order to view the media, while transcoding - I convert the source file into hls format. I don’t really like this approach, as every user has a storage limit and he has to use his space for storing both hls and source files, even if he is not going to watch the video while encoding. What would be the best solution in this case ?

• How to install a Matomo premium feature

  31 janvier 2018, par InnoCraft

  You may have noticed over the last few months that many fantastic new features have been launched on the Matomo Marketplace. As some of them are paid premium features, you may wonder if the process to install them is straightforward, if you can test them before, and whether there is any support behind it. No worries – we’ve got you covered ! This blog post will answer some questions you may have about getting your first premium plugin.

  So why are there some premium features ?

  Researching, building, documenting, testing and maintaining quality products take years of experience and months of hard work by the team behind the scenes. When you purchase a premium plugin, you get a fully working product and you directly help the Matomo core engineers to grow and fund the new Free Matomo versions and cool features.

  However, it is important for us to mention that Matomo will always be free, it is a Free software under GPLv3 license and it will always be the same.
  Want to know more about this ? Check out our FAQ about why there are premium features.

  Can I test a premium feature before a purchase ?

  Absolutely. There are two ways in order to do that :

  1. InnoCraft Matomo Cloud
  2. Matomo Marketplace

  1. InnoCraft Matomo Cloud

  The easiest way is to create a free trial account (one minute of your time) on our Matomo cloud service. You will then have the possibility to test all the premium features during a 30-day trial period. No credit card is required.

  

  Every premium feature can be trialled for free on the Matomo Cloud

  2. Matomo Marketplace

  The second way is to get the premium feature from the Matomo Marketplace. We have an easy and hassle-free 30-day money back guarantee period on each feature. This means that if you are not happy with a premium feature and you are within the 30-day period, then you will get a full refund for it. Guaranteed !

  How to purchase and install a premium feature ?

  Step 1 : Purchasing the feature

  In order to get a premium feature, just add it to the cart :

  

  Once done, go to your cart and complete the checkout process to confirm the order.

  When the order is confirmed, you immediately get your license key on the order confirmation page. You also receive the license key by email.

  Step 2 : Activating the feature in your Matomo

  Now that you have received the license key, it is time to activate the plugin in your Matomo :

  • Log in to your Matomo and go to “Administration => Marketplace
  • Copy / paste the license key into the license field at the top of the page and click “Activate”

  

  • The key will now be activated and you will see a couple of new buttons.

  

  • To install the premium feature(s) you just purchased in one click, simply click on “Install purchased plugins”. Alternatively, you can scroll down in the Marketplace to the premium feature you purchased and click on “Install”. You can also download the ZIP file on https://shop.matomo.org/my-account/downloads

  And that’s it. The installation of a premium feature is as easy as copy/pasting the license key and clicking a button. Because one license key is linked to all purchased premium features, you only need to enter the license key once. The next time you purchase a premium feature, you simply click on “Install” to have it up and running.

  Updating a premium feature

  Updates for premium features work just like regular plugin updates. When there is a new update available, you will see a notification in the Matomo UI and also receive an email (if enabled under “General Settings”). To upgrade the feature simply click on “Update” and you’re done.

  Which support is provided for each of those premium features ?

  Premium features represent most of our day to day activity, so you can be 100% sure that we will do our maximum in order to answer any of your questions regarding them. To be 100% transparent, we often receive answers from our customers telling us how impressed they are by the quality of the service we are offering.

  Have any questions ?

  We are happy to answer any questions you may have so feel free to get in touch with us.

  Thanks !

• Converting to mp4 with ffmpeg takes too much time

  19 octobre 2022, par rwehresmann

  I have a cloud function where I'm trying to convert small octet-stream (captured from the webcam) to mp4 videos, however, it takes a huge amount of time to convert even a small stream (112.17 KB). I cannot finish the conversion below the timeout of 500 seconds in my cloud function.

  


  Here is my node server :

  


  #!/usr/bin/env node

const express = require('express')
const app = express()
const router = express.Router()
const func = require('./index')
const bodyParser = require('body-parser')

app.use(bodyParser.raw({ type: 'application/octet-stream' }))
router.post('/transcoder', func.transcode)
router.options('/transcoder', func.transcode)
app.use('/', router)

// start the server
const port = 3030
const http = require('http')
app.set('port', port)
const server = http.createServer(app)
server.listen(port)


  


  The function that does the conversion :

  


  const functions = require('@google-cloud/functions-framework');
const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path
const FfmpegCommand = require('fluent-ffmpeg')
const fs = require('fs')
const path = require('path')
const stream = require('stream')
const cors = require('cors')({ origin: true })

FfmpegCommand.setFfmpegPath(ffmpegPath)

class WritableChunkCache extends stream.Writable {
    constructor(options) {
        super(options)
        this._chunks = []
    }

    write(chunk, encoding, callback) {
        this._chunks.push(chunk)
        if(typeof callback === 'function') callback()
    }

    writev(chunks, callback) {
        this._chunks = this._chunks.concat(chunks)
        if(typeof callback === 'function') callback()
    }

    get buffer(){
        return Buffer.concat(this._chunks)
    }
}

functions.http('mp4Transcoder', (req, res) => {
   try {
    res.set('Access-Control-Allow-Origin', '*');
    res.set('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');
    res.set('Access-Control-Allow-Headers', 'Content-Type');
    res.set('Access-Control-Allow-Credentials', true);

    if (req.method === 'OPTIONS') {
        res.set('Access-Control-Allow-Origin', '*');
        res.set('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');
        res.set('Access-Control-Allow-Headers', 'Content-Type');
        res.set('Access-Control-Allow-Credentials', true);
        res.status(204).send('');
    } else {
      cors(req, res, () => {});

      // for compatibility between dev-server and live cloud function
      if (!req.rawBody) {
        req.rawBody = req.body
      }

      if (req.rawBody) {
        const readStream = new stream.PassThrough()
        readStream.end(req.rawBody)
        const outStream = new WritableChunkCache()

        const command = new FfmpegCommand(readStream)
            .on('end', () => {
              console.log("Finished transcoding.")
              res.send(outStream.buffer)
             })
            .on('error', (err, ...args) => {
              console.error(err, args)
              res.status(500).send(err)
            })
            .format('mp4')
            .outputOptions(['-movflags frag_keyframe+empty_moov'])
            .pipe(outStream, { end: true })
      } else {
        res.status(400).send("No video file sent.")
      }
    }
  } catch (e) {
    console.log(e)
    res.status(500).send(e)
  }
});


  


  I'm not concerned with the video quality. Any idea of how could I improve the conversion time ?
