• How to process remote audio/video stream on WebRTC server in real-time ? [closed]

  7 septembre 2020, par Kartik Rokde

  I'm new to audio/video streaming. I'm using AntMedia Pro for audio/video conferencing. There will be 5-8 hosts who will be speaking and the expected audience size would be 15-20k (need to mention this as it won't be a P2P conferencing, but an MCU architecture).

  


  I want to give a feature where a user can request for "convert voice to female / robot / whatever", which would let the user hear the manipulated voice in the conference.

  


  From what I know is that I want to do a real-time processing on the server to be able to do this. I want to intercept the stream on the server, and do some processing (change the voice) on each of the tracks, and stream it back to the requestor.

  


  The first challenge I'm facing is how to get the stream and/or the individual tracks on the server ?

  


  I did some research on how to process remote WebRTC streams, real-time on the server. I came across some keywords like RTMP ingestion, ffmpeg.

  


  Here are a few questions I went through, but didn't find answers that I'm looking for :

  


  

  1. Receive webRTC video stream using python opencv in real-time

  


  2. Extract frames as images from an RTMP stream in real-time

  


  3. android stream real time video to streaming server

  


  


  I need help in receiving real-time stream on the server (any technology - preferable Python, Golang) and streaming it back.

  


• Introducing Improvements to the Opt-Out Form Feature

  18 septembre 2022, par Ben — About

  Matomo includes a built-in opt-out form that you can add to your website so you can provide your visitors with the choice to opt-out of Matomo tracking. Up until Matomo 4.12.0 the built-in opt-out form relied on iFrame technology which has become increasingly problematic due to browser changes and restrictions on setting third-party cookies.

  With our privacy-first approach, we’ve known for some time that we would eventually need a new way to provide this important opt-out functionality that would work most reliably in the myriad of contexts our users rely on it for.

  Embedding the opt-out form

  Matomo 4.12.0 introduces an improved opt-out. This provides two new options for embedding the opt-out on your website, either using the Matomo tracker code or as self-contained code.

  

  As with the iFrame method, the built-in opt-out code can be styled in Matomo to match your website, and provides a snippet which you can add to your website to show the opt-out feature to your users.

  Find out how to customise the opt-out form.

  Customising the opt-out form

  

  What does this mean for existing opt-out forms ?

  Although it is no longer possible to generate new iFrame embed code using the Matomo UI, the underlying opt-out feature is still fully supported and any existing iFrame opt-out form code embedded in websites will still work as before. It is recommended to migrate to one of the new opt-out form options as browser support for the iFrame opt-out will continue to decrease.

  To read more in depth information about the new opt-out functionality please refer to our new developer documentation for tracking opt-out.

• Game Music Appreciation

  16 juillet 2012, par Multimedia Mike — Game Hacking

  A little over a year ago, I was prototyping a method to leverage Google Chrome’s Native Client technology in order to play old chiptunes (video game music) directly in a web browser. The last time I posted on the matter, I said that I might have something ready for public consumption by the time Google Chrome 21 rolled around. I thought I was being facetious but I wasn’t too far off. Chrome 20 is the current release version as I write this.

  Anyway, I did it : I created a chiptune music player in Native Client by leveraging existing C/C++ libraries such as Game Music Emu, Audio Overload SDK, and Vio2sf. Then I packaged up the player into into a Google Chrome extension and published it on the Chrome Web Store. Then I made a website cataloging as many chiptunes as I could find for 7 different systems :

  http://gamemusic.multimedia.cx/
  

  Check it out if you have any affinity for old game music or you want to hear how music was made using a limited range of bleeps and bloops. Thus far, the site catalogs NES, SNES, Game Boy, Nintendo DS, Genesis, Saturn, and Dreamcast songs. I’m hoping to add support and catalogs for many more systems, though, eventually bringing support in line with the Chipamp plugin for Winamp.
