• Scalable Video Stream Processing and Redirection in the Cloud - More Efficient Alternatives to RTMP ?

  18 juillet 2023, par dumbQuestions

  I'm currently working on a project that involves processing and redirecting video streams from multiple users in real time.

  


  Here's how my current implementation works :

  


  


  • Users send their video streams to an RTMP server.

    


  


  • I use OpenCV to connect to the source RTMP server and capture the video stream.
The video frames are processed using OpenCV.

    


  


  • I then use FFmpeg to forward the processed video stream to another RTMP server.

    


  


  


  I want to deploy it with cloud providers, but I'm worried that RTMP servers might not be the best choice for scalability, especially with increasing users. I'm seeking recommendations for efficiently implementing such video stream processing and redirection with good scalability. Is my current implementation somewhat viable, is there a better solution ?

  


  Ideally, I'm looking for solutions that can handle a large number of concurrent video streams and provide low latency

  


  Is there a cloud-based alternative to the RTMP-based approach that can meet these requirements and offer better scalability and efficiency ? Any insights, experiences, or recommendations are greatly appreciated. Thank you !

  


• Leading Google Analytics alternative, Matomo, parodies Christopher Nolan blockbuster ahead of the UA sunset

  4 juillet 2023, par Erin — Press Releases

  Wellington, New Zealand, 4 July 2023 : In the world of online data, Google Analytics has long reigned supreme. Its dominance has been unquestioned, leaving website owners with little choice but to rely on the tech giant for their data insights. However, a new dawn in web analytics is upon us, and Matomo, the leading alternative to Google Analytics, is seizing a unique opportunity to position itself as the go-to provider. In a bold move, Matomo has launched a parody trailer, “Googleheimer,” humorously taking a satirical swipe at Google in the style of the upcoming Oppenheimer biopic by Christopher Nolan.

  Capitalising on a time-bound decision

  With an important decision looming for marketers and web specialists who need to switch analytics providers by July 1st, Matomo has found the perfect window to capture their attention.

  The urgency of the situation, combined with the high intent to switch providers, sets the stage for Matomo to establish itself as the leading alternative analytics platform of choice.

  Matomo’s parody trailer addresses the frustrations of GA4 head-on by highlighting the issues and the uncertainties caused by the sunset of Universal Analytics in humorous satire with lines such as :

  “But we’re keeping everyone’s data, right ? Right ?? …RIGHT ?!”

  Riding on the coat tails of this summer’s anticipated blockbuster from Christopher Nolan, Matomo openly points at the downsides of GA4, and reflects many frustrated marketers pain points in an entertaining way. Beneath the comedic and satirical tone lies the message that users have choices, and no longer need to surrender to the behemoth incumbent.

  Matomo was founded to challenge the status quo and provide a solution for those who believe in privacy and in ethical analytics, and who prefer that their customer data not be concentrated in the hands of just a few corporations.

  Watch the full trailer here.

  More on Google Analytics changes



  A new dawn in web analytics is upon us, and Matomo – the leading alternative to Google Analytics – is here for it. After 20 years, Google is blowing up Universal Analytics (or GA3) – and taking your data with it. Inspired by Christopher Nolan’s upcoming biopic about physicist J. Robert Oppenheimer and the making of his atomic bomb (also known as “The Manhattan Project”), this parody trailer openly points to Google and draws the comparison in humorous satire. GA4 comes with a new set of metrics, setups and reports that change how you analyse your data.

• fftools/ffmpeg_mux : stop rescaling timestamps in of_streamcopy()

  25 juillet 2023, par Anton Khirnov

  fftools/ffmpeg_mux : stop rescaling timestamps in of_streamcopy()
  This function converts packet timestamps from the input stream timebase
  
  to OutputStream.mux_timebase, which may or may not be equal to the
  
  actual output AVStream timebase (and even when it is, this may not
  
  always be the optimal choice due to bitstream filtering).
  Just keep the timestamps in input stream timebase, they will be rescaled
  
  as needed before bitstream filtering and/or sending the packet to the
  
  muxer.
  Move the av_rescale_delta() call for audio (needed to preserve accuracy
  
  with coarse demuxer timebases) to write_packet.
  Drop now-unused OutputStream.mux_timebase.
