• How to use FFmpeg to live HLS stream with subtitle ?

  17 août 2023, par iHad 169

  I want to use FFmpeg to live HLS stream with subtitle.
I have a Media. The Media have one video track, two audio track, four subtitle.
But, I tryed this command :

• Is it possible to force ffmpeg to use hardware decoding with H.264 input stream ?

  27 août 2018, par Ryan Griggs

  I am running a raspberry pi 3B with ffmpeg compiled with the —enable-omx-rpi option. I am trying to do frame-capture from a webcam stream (h.264, 1920x1080) to JPG files at 5 frames per second. This operation currently causes the board to show very high CPU utilization and get very hot. For this reason, I am assuming hardware decoder is not being utilized.

  Is there a way to 1) determine whether ffmpeg is using hardware decoding, and 2) force it to be enabled ?

• New Matomo Mobile 2.4.0 released

  12 janvier 2018, par Matomo Core Team

  New Matomo Mobile 2.4.0 update is now available for Android 6+ and iOS10.3+ devices. This is the first mobile release that shows signs of the new Matomo branding instead of Piwik. Don’t be surprised if the app still shows the Piwik app icon. This is on purpose as the name of the app changed to Matomo Mobile and some users would otherwise not find the app anymore if they haven’t heard of the renaming from Piwik to Matomo before.

  What’s new in Matomo Mobile ?

  This new version brings some bug fixes and improvements to our Android and iOS apps :

  • Piwik is now Matomo which includes some name changes in the app as well as showing the new logo
  • Fixed broken “Get-involved” link
  • Links to Matomo or other websites now open in the browser app and no longer in the app itself
  • Improved visitor log to support more actions (see #12284)
  • We have updated the underlying framework bringing some performance and compatibility improvements

  Download the Apps

  Update now or install either the iOS version or the Android version. Android users can also download the latest version from our website : download Matomo Mobile 2.4.0 from our website.
