• Matomo’s new story : our stronger vision for the future

  31 octobre 2018, par Matthieu Aubry — Community

  

  Over the past year, the team here at Matomo have been working on a very exciting project we’d love to share with you.

  It’s to do with the impact we hope for Matomo to have.

  As you all know, the world changes at too fast a pace. New technologies, new phones, new everything in the blink of an eye. That’s not what will be happening here.

  Instead, we’d like to believe it’s a refresh. Taking stock of how far we’ve come, what we’ve achieved so far, and how far we still have to go.

  So we’re rebranding.

  The rebrand

  Like a caterpillar emerging from a cocoon, we hope to be a reborn analytics butterfly.

  As a result of some careful planning and reflection we’ll be updating our logo, website and reasserting our voice.

  It’s our chance to look at ourselves in a new light. We are a mighty analytics platform and it should be known we’re comparable to the likes of Google Analytics 360.

  Along with the refresh of imagery, we listened to your feedback about the confusion between our two identities, so we’re also taking this opportunity to unite both the business brand of Innocraft with the community brand Matomo into one website.

  It makes it easier for people from all walks of life, either as individuals or in large companies, to see us as being able to get down to business with a powerful analytics tool, as well as think on behalf of our community.

  We’re the same, but with slight changes in our appearance and a stronger vision for the future.

  How far we’ve come …

  When we started out, it was about building a community around a movement. From the beginning we were concerned about data ownership, privacy and all things that came with that.

  With the help of our community and contributors, we turned Matomo (formerly Piwik) into the trusted #1 open source analytics tool it is today. We’re committed to our community. But we also need to do more.

  We’ve been niche and happy staying small, but now we need to take action and start shouting far and wide about what we do.

  We once said we need : “To create, as a community, the leading international open source digital analytics platform, that gives every user full control of their data.”

  We believe we’ve done that, so we’ll take it one step further.

  A web analytics revolution has begun …

  Begun ?

  The line signifies a new beginning.

  This is us standing up and reasserting our voice.

  Our new chapter.

  The rebrand is our chance to show that, yes, the world is changing, but when it comes to privacy, there are matters meant to be sacred. Privacy is a human right.

  What makes it worse in this ever-changing landscape, with data breaches and stolen information, is that losing control of our data is scary, we have a right to know what’s going on with our information and this must start with us.

  We know we need to champion this cause for privacy and data ownership.

  We came together as a community and built something powerful, a free open-source analytics platform, that kept the integrity of the people using it.

  It’s important for us now to feel more empowered to believe in our right to privacy, information and our ability to act independently of large corporations.

  The time is here for us to speak up and take back control.

  Once more, we need to come together to build something even more powerful, a safer online society.

  Join us.

  Sincerely,
  Matthieu Aubry on behalf of the Matomo team

• FFmpeg upmix command stereo > 5.1

  2 octobre 2018, par CupNoodleFanatic

  I need to upmix stereo mkv files with chapter, subtitle, audio and video streams to 5.1 flac with a silent center channel. The audio is a single stereo stream, not two mono streams. I need the resulting mkv to contain a single 6 channel flac stream.

  My desired channel layout is FR = FR, FR > SR, FL = FL, FL > SL, Center silent, LFE = FR+FL

  I followed the FFmpeg documentation and was unable to produce the desired mapping.

  The command so far (generated with help from Axiom GUI) :

  ./ffmpeg -i TestIN.mkv -c:v copy -map 0:v? -map_chapters 0 -c:s copy -map 0:s? -c:a flac -sample_fmt s16 -rematrix_maxval 1.0 -ac 6 -map 0:a:0? -map_metadata 0 -f matroska -threads 0 X:\TestOUT.mkv

  Any help would be greatly appreciated.

• Creating a sequence of images from lyrics to use in ffmpeg

  19 septembre 2018, par SKS

  I’m trying to make an MP3 + Lyric -> MP4 program in python.

  I have a lyrics file like this :

  [00:00.60]Revelation, chapter 4
  
  [00:02.34]After these things I looked, 
  
  [00:04.10]and behold a door was opened in heaven, 
  
  [00:06.41]and the first voice which I heard, as it were, 
  
  [00:08.78]of a trumpet speaking with me, said: 
  
  [00:11.09]Come up hither, 
  
  [00:12.16]and I will shew thee the things which must be done hereafter.
  
  [00:15.78]And immediately I was in the spirit: 
  
  [00:18.03]and behold there was a throne set in heaven, 
  
  [00:20.72]and upon the throne one sitting.
  
  [00:22.85]And he that sat, 
  
  [00:23.91]was to the sight like the jasper and the sardine stone; 
  
  [00:26.97]and there was a rainbow round about the throne, 
  
  [00:29.16]in sight like unto an emerald.
  
  [00:31.35]And round about the throne were four and twenty seats; 
  
  [00:34.85]and upon the seats, four and twenty ancients sitting, 
  
  [00:38.03]clothed in white garments, and on their heads were crowns of gold.
  
  [00:41.97]And from the throne proceeded lightnings, and voices, and thunders; 
  
  [00:46.03]and there were seven lamps burning before the throne, 
  
  [00:48.60]which are the seven spirits of God. 
  
  [00:51.23]And in the sight of the throne was, as it were, 
  
  [00:53.79]a sea of glass like to crystal; 
  
  [00:56.16]and in the midst of the throne, and round about the throne, 
  
  [00:59.29]were four living creatures, full of eyes before and behind.
  
  [01:03.79]And the first living creature was like a lion: 

  I’m trying to create a sequence of images from the lyrics to use into ffmpeg.

  os.system(ffmpeg_path + " -r 2 -i " + images_path + "image%1d.png -i " + audio_file + " -vcodec mpeg4 -y " + video_name)

  I tried finding out the number of images to make for each line. I’ve tried subtracting the seconds of the next line from the current line. It works but produces very inconsistent results.

  import os
  
  import datetime
  
  import time
  
  import math
  
  from PIL import Image, ImageDraw
  
  
  
  
  
  ffmpeg_path = os.getcwd() + "\\ffmpeg\\bin\\ffmpeg.exe"
  
  images_path = os.getcwd() + "\\test_output\\"
  
  audio_file = os.getcwd() + "\\audio.mp3"
  
  lyric_file = os.getcwd() + "\\lyric.lrc"
  
  
  
  video_name = "movie.mp4"
  
  
  
  
  
  def save():
  
  
  
      lyric_to_images()
  
      os.system(ffmpeg_path + " -r 2 -i " + images_path + "image%1d.png -i " + audio_file + " -vcodec mpeg4 -y " + video_name)
  
  
  
  
  
  def lyric_to_images():
  
  
  
      file  = open(lyric_file, "r")
  
  
  
      data = file.readlines()
  
  
  
      startOfLyric = True
  
      lstTimestamp = []
  
  
  
      images_to_make = 0
  
      from_second = 0.0
  
      to_second = 0.0
  
  
  
      for line in data:
  
          vTime = line[1:9] # 00:00.60
  
  
  
          temp = vTime.split(':')
  
  
  
          minute = float(temp[0])
  
          #a = float(temp[1].split('.'))
  
          #second = float((minute * 60) + int(a[0]))
  
          second = (minute * 60) + float(temp[1])
  
  
  
          lstTimestamp.append(second)
  
  
  
      counter = 1
  
  
  
      for i, second in enumerate(lstTimestamp):
  
  
  
          if startOfLyric is True:
  
              startOfLyric = False
  
              #first line is always 3 seconds (images to make = 3x2)
  
              for x in range(1, 7):
  
                  writeImage(data[i][10:], 'image' + str(counter))
  
                  counter += 1
  
          else:
  
              from_second = lstTimestamp[i-1]
  
              to_second = second
  
  
  
              difference = to_second - from_second
  
              images_to_make = int(difference * 2)
  
  
  
              for x in range(1, int(images_to_make+1)):
  
                  writeImage(data[i-1][10:], 'image'+str(counter))
  
                  counter += 1
  
  
  
      file.close()
  
  
  
  def writeImage(v_text, filename):
  
  
  
      img = Image.new('RGB', (480, 320), color = (73, 109, 137))
  
  
  
      d = ImageDraw.Draw(img)
  
      d.text((10,10), v_text, fill=(255,255,0))
  
  
  
      img.save(os.getcwd() + "\\test_output\\" + filename + ".png")
  
  
  
  
  
  save()

  Is there any efficient and accurate way to calculate how many images I need to create for each line ?

  Note : Whatever many images I create will have to be multiplied by 2 because I’m using -r 2 for FFmpeg (2 FPS).
