• VideoJS for HLS streaming not working on iOS

  13 février 2024, par Aames

  I have a website where I stream audio using HLS (m3u8 playlist + ts files).
I use VideoJS 8.3.0 to handle the stream in the frontend side.
The streaming works in all devices (PC, Android, Mac) except in iOS where it works intermittently and often it blocks.

  


  Here is my videojs initialization :

  


  player = videojs('stream-id', {
            controls: false, autoplay: true, preload: 'auto',
            html5: {
               vhs: {overrideNative: false},
               nativeAudioTracks: true
           }
        });

...

player.src({ type: 'application/x-mpegURL', src: 'https://.../master.m3u8' });



  


  And these are the headers of the m3u8 file :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-PROGRAM-DATE-TIME:2024-02-13T09:00:00Z
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-DISCONTINUITY
#EXTINF:10.007800,
master0.ts
#EXTINF:7.214989,
master1.ts
....


  


  I use ffmpeg to create the playlist from mp3 files :

  


  ffmpeg -i inputFileName -c:a aac -b:a 128k -ac 2 -f hls -hls_time 10 -preset ultrafast -map 0:a -flags -global_header -hls_list_size 0 -hls_flags append_list outputFileName



  


  Am I doing something wrong ? Any help would be appreciated
Thanks

  


  I tried this solution : Videojs HLS m3u8 files are not playing in iOS devices and safari browser but it does not work for me

  


• FFmpeg and reserved color primaries [closed]

  21 janvier, par Yoz

  I am trying to get thumbnails from a hevc video downloaded from https://github.com/stashapp/stash/issues/4124#issuecomment-1720057183 and it works with most recent ffmpeg 7.1 (installed via homebrew on mac) printing :

  I figured out the issue is color primaries prim:reserved, and the command can be updated to a working one by re-writing input primaries as following :

  


  ffmpeg -i input.mp4 -vf "colorspace=all=bt709:iprimaries=bt709" -frames:v 1 out.jpg


  


  However, I would like to compile ffmpeg.wasm so that it handles reserved primaries just like the one from homebrew.

  


  Any idea what the compiled ffmpeg.wasm is missing ?

  • Enhanced account security features including a “This Wasn’t Me” link in password reset emails and location-based login alerts
  • The new Global List of Query URL parameters feature lets you refine tracking by excluding sensitive or unnecessary parameters from collection

  Tag manager improvements for better efficiency

  

  The Matomo Tag Manager now includes several features to streamline your workflow :

  • New Consent Management Platform (CMP) tags for CookieYes, OneTrust, and Axeptio, simplifying consent tracking implementatio.
  • A new copy feature for containers, tags, and triggers that reduces setup time and ensures consistency across multiple properties
  • Improved management tools for maintaining standardised tracking across websites

  Performance and reliability updates

  We’ve made technical improvements to enhance Matomo’s performance :

  • Full PHP 8.4 compatibility for improved performance and reliability
  • Optimised archiving processes including smarter handling of recent data
  • New recovery options for interrupted archiving processes
  • Specific improvements for TiDB compatibility, enhancing database performance for users of this engine

  Important to note : This release does not require any major database upgrade, making it easier to implement these improvements.

  Looking forward to 2025
