  7 janvier 2022, par erin — Community, Press Releases

  Matomo is the leading open-source analytics solution free from data limitations. 

  As our mission states, we aim to create, as a community, the leading open digital analytics platform that gives every user full control of their data.

  To continue our investment in security, privacy and transparency, we are increasing the security bug bounty reward to as much as $10,000 USD. This is an increase of 100% from our previous 2020 bug bounty announcement.

  How much can I earn for reporting security bugs ?

  Reward amounts vary depending on the impact :

  • Low issues receive $222
  • Medium issues receive $555
  • High issues receive $1,000
  • Critical issues receive $10,000

  How can I take part ? 

  As of January 2022, global independent security researchers have identified and suggested 138 security related improvements. If you are interested in joining this growing community, head to our Security Bug Bounty Programme to find out how you can take part. 

  We thank you for keeping Matomo safe for our users and theirs.

• Stream PNG file to youtube with ffmpeg

  3 avril 2022, par codingmaster398

  What I'm trying to do :
I have a PNG file that is constantly getting written to. I want to pipe it (while it changes) to YouTube's RTMP server.

  


  What I've attempted :

  


  runCommand(
      'ffmpeg',
      `-threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 512 \
-loop 1 -re -i place.png \
-stream_loop -1 \
-filter:v "crop=in_w/2:in_h/2:1920:1280" \

    () => {},
    () => console.log('finished')
)

setInterval(()=>{
  image.write('./place.png') // Jimp },5000)
