    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;

  • Tv box failed to open encoded videos using x265 HEVC encoder

    3 juin 2022, par Constadinos Chatzis

    I have Zidoo X9S tv box and it has support for x265 HEVC codec. Every single video i throw in it, HDR 4K or standard x264 videos, it plays perfectly except my encoded x265 video when i select it to play, it freezes and it doesn't load. I believe it has something to do with my encoding settings. The encoding command i use with ffmpeg, is this :

    


    -c:v libx265 -crf 10 -preset veryfast output.mkv


    


    Any ideas why this is happening ?

    


  • Cannot concatenate videos ffmpeg [on hold]

    1er mai 2014, par Paul Prescod

    I have a bitmap that I would like to concatenate to the front of many videos as a sort of title screen or disclaimer screen.

    I try to turn it into a video with the same attributes as the rest of the video. So first I introspect the video :

    Then I try and create a similar file :

    It seems to work okay. The video plays I would expect it to. The attributes turn out very similar. Here is a diff :

    But when I try to concatenate, I get errors.

    The output looks like it only has my disclaimer file in it, not the rest of the video.

    I’m also confused why it feels like it needs to "estimate" anything. It knows the input FPS and input durations. I’m not sure if this is the problem or not. Maybe its just a bug.

  • Extract music metadata (music title, album title, artist name...) using react-player

    6 juin 2022, par Pierogi

    I'm building a simple web app that plays music streams.
    
The constitution of the web app is

    


    audio.m4a -> ffmpeg -> nginx + rtmp module -> frontend browser

    


    In the frontend browser, use react-player.
    
The audio data is published as HLS audio data.

    


    So, I want to extract the metadata(music title, album title, artist name ...) from the data and display it in the browser. However, I could not find the way to that.
    
Anyone who knows this ?
