  Fifteen years ago, I realised that people (myself included) were increasingly integrating the internet into their everyday lives, and it was clear that it would only expand in the future. It was an exciting new world, but the amount of personal data shared online, level of tracking and lack of security was a growing concern. Google Analytics was just launched then and was already gaining huge traction – so data from millions of websites started flowing into Google’s database, creating what was then the biggest centralised database about people worldwide and their actions online.

  So as a young engineering student, I decided we needed to build an open source and transparent solution that could help make the internet more secure and private while still providing organisations with powerful insights. I aimed to create a win-win solution for businesses and their digital consumers.

  And in 2007, I started developing Matomo with the help from Scott Switzer and Jennifer Langdon (who offered me an internship and support).   

  All thanks to the Matomo Community

  We have reached significant milestones and made major changes over the last 15 years, but we wouldn’t be where we are today without the Matomo Community.

  So I would like to celebrate and thank the hundreds of volunteer developers who have donated their time to develop Matomo, the thousands of contributors who provided feedback to improve Matomo, the countless supportive forum members, our passionate team of 40 at Matomo, the numerous translators who have translated Matomo and the 1.5 million websites that choose Matomo as their analytics platform.

  

  Matomo has been a community effort built on the shoulders of many, and we will continue to work for you. 

  So let’s look at some milestones we have achieved over the last 15 years.

  Our efforts continue

  While we’ve seen incredible growth over the years, our work doesn’t stop there. In fact, we’re only just getting started.

  Today over 55% of the internet continues to use privacy-threatening web analytics solutions, while 1.5% uses Matomo. So there are still great strides to be made to create a more private internet, and joining the Matomo Community is one way to support this movement.

  There are many ways to get involved too, such as :

  • Submitting feature requests
  • Developing for Matomo 
  • Leaving Matomo a review on sites like Capterra, TrustRadius, G2 Crowd, alternativeTo, SaaSworthy, Siftery, Open Hub
  • Translating Matomo
  • Joining our Security Bug Bounty Programme
  • Sharing Matomo with your peers
  • Talking about Matomo on social platforms

  So what comes next for Matomo ?

  The future of Matomo is approachable, powerful and flexible. We’re strengthening the customers’ voice, expanding our resources internally (we’re continuously hiring !) and conducting rigorous customer research to craft a tool that balances usability and functionality.

  I look forward to the next 15 years and seeing what the future holds for Matomo and our community.

• Transcode WEBM to RTMP

  7 avril 2024, par Justin White

  Summary

  


  My goal is to take a webcam stream from the browser and feed it into a program called Restreamer that takes in an RTMP stream.

  


  I've deduced that the browser Recording API produces Blobs that can be saved as WEBM.

  


  In order to stream the WEBM content to Restreamer I am attempting to use FFmpeg. I've read that forcing FLV format is required but otherwise all of the arguments are Greek to me. I've been unable to find a comparable topic where someone has tried to go from WEBM to RTMP. I have found examples of going the other direction, but reversing the FFmpeg command proved unfruitful.

  


  Saving to FLV works fine. Using the following command, I am able to transcode a WEBM file to FLV and play it on VLC :
  
ffmpeg -i ~/big-buck-bunny_trailer.webm -f flv out.flv

  


  However, if instead of outputting to a file I pass it to RTMP I get the following output :
  
ffmpeg -i ~/Downloads/big-buck-bunny_trailer.webm -f flv "rtmp://example.com/live"

  There are several interesting rabbit holes to follow here, but after following all of them I've come up with nothing.

  


  • HandShake: client signature does not match! :
  
More of a warning than an error, I assumed because I was going from "WEBM -> FLV" instead of the more traditional "MP4 -> FLV".

  


  • av_interleaved_write_frame(): Operation not permitted :
  
I found several issues on this. One of them calling it a storage issue, the other calling it a file permissions issue. I have plenty of disk space and have tried setting the input file to 777 permissions. However, the examples I've found on it being a file permissions issue all deal with outputting to a file rather than to an an RTMP IP.

  


  • Failed to update header with correct duration :
  
Advice I found was to add -flvflags no_duration_filesize to the command, which does suppress both "Failed to update..." errors, but does not fix the over-arching issue.

  


  What I've Tried

  


  • Multi-format transcoding

  


  MP4 to RTMP does work correctly :
  
ffmpeg -i ~/Downloads/big-buck-bunny_trailer.mp4 -f flv "rtmp://example.com/live"
  
Theoretically, I could stream the WEBM to a file, transcode that to an MP4 file, and then transcode that to FLV/RTMP. Sounds awful.

  


  • Pay for a service (Wowza, Flashphoner, api.video, etc)

  


  Unfortunately precisely what I am trying to avoid.

  


  • WebRTC to RTMP ?

  


  WebRTC seems to be a peer-to-peer connection and doesn't play nicely with a server/client scenario.

  


  • WebRTC to other ingest formats

  


  Restreamer also supports incoming streams of HLS, DASH, RTP, RTSP, RTMP, and SRT. However, these all seem to be examples of network sources that would be exposed via an IP URL. I am not sure that FFmpeg can do that.

  


  • Utilizing ffmpeg-wasm instead of CLI

  


  Available here, I thought that maybe by using a browser implementation I may get different results. But no. Not even an error to the console.

  


  • Streaming from OBS

  


  For the record, yes, I have tried streaming from OBS instead of going through FFmpeg and the Restreamer platform itself does work for normal use. I use it often.

  


  Post Script

  


  I've not been able to find any relevant solutions online. I am shocked that streaming from a browser webcam has not been solved 1000 times prior. This is related to a question made 7 years ago but it was not resolved and Flash is no longer an option.

• FFmpeg fails to draw text

  6 avril 2024, par Edoardo Balducci

  I've rarely used ffmpeg before, so, sorry If the question is too dumb.
I have a problem adding a text layer to a video frame using ffmpeg.

  


  This is my current code :

  


  import subprocess
from PyQt5.QtGui import QPixmap, QImage
from PyQt5.QtWidgets import QLabel

class VideoThumbnailLabel(QLabel):
    def __init__(self, file_path, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.video = video

  and it is used like this :

  


  for i, video in enumerate(self.videos):
    video_widget = VideoThumbnailLabel(video.file)
    video_widget.mousePressEvent = lambda event, v=video: self.onThumbnailClick(
        v
    )
    self.layout.addWidget(video_widget, i // 3, i % 3)


  


  I'm facing a problem where I am not able to get the thumbnail if I try to add the duration (I've tested it without the draw filter and worked fine)

  


  I get this error (from the result.returncode) that I'm not able to comprehend :

  Does anyone see the problem ?

  P.S. : I know that I havent provided a minimal reproducible example, but since I don't know where the problem lies I didn't want to exclude anything
