  • Configuration spécifique d’Apache

    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 ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • @ffmpeg/ffmpeg : Uncaught (in promise) ReferenceError : SharedArrayBuffer is not defined

    19 mai 2022, par Flobbinhood

    I have a small react app with a node.js backend (monorepo). The client is using @ffmpeg/ffmpeg, and all works fine locally, but when deployed to Heroku I'm getting the error ReferenceError: SharedArrayBuffer is not defined. This happens when I run ffmpeg.load(). Note that I am only using ffmpeg on the client in the React app.

    


    What I have done so far :

    


      

    • Ensured that my deployed app is using https

      • 


    • Added these lines in setupProxy.js in app.use (located in the client directory). See this answer for context

      • 


    


    response.setHeader('Cross-Origin-Opener-Policy', 'same-origin');
response.setHeader('Cross-Origin-Embedder-Policy', 'require-corp');


    


      

    • Registered for an origin trial with chrome. This actually worked, but I'd prefer a more permanent solution that works across browsers.

      • 


    • Tested debugging crossOriginIsolated, and verifying that it is true locally but false on my deployed site.

      • 


    


    It seems like something is wrong with my Cross-Origin config, or maybe it's just not being applied. Any help would be appreciated.

    


  • ffmpeg convert vp9 video to mp4

    6 mai 2017, par Sulli

    I am using this command

    ffmpeg -i $youtubeUrl -strict -2 -c copy output.mp4

    (with $youtubeUrl generated by youtube-dl) to download this youtube video : https://www.youtube.com/watch?v=wnCJhq-JOck

    I can’t play the downloaded video though on Ubuntu or Windows (for a problem of vp09 codec) and I have to convert the video to webm and then back to mp4 to be able to play it :

    ffmpeg -i output.mp4 -vcodec libvpx-vp9 -strict experimental output_2.webm
    
ffmpeg -i output_2.webm -strict 2 output_3.mp4

    This happens only with some youtube videos, not all of them.

    Is there a way to download all youtube videos in a readable format with only one command line, without having to convert to webm ?

  • FFMPEG - speed up/slow down video, add jitter etc

    27 septembre 2019, par Darrell

    I’m trying to put together a Windows script that will process short videos in a folder.
    The videos will be shot at a high frame rate 60+ fps and be about 4-5 secs long.

    Basically I am looking to make various style clips, using fast/slow effects, back and forth etc.
    So, the script might process a video, make it start normal speed, then slow motion. Next video might be normal speed, slomo, normal speed slomo. Next video might be forwards,back, forwards back, slomo.

    See example : (this is a compliation, I’m looking at processing individual videos in a folder.)

    I’m guessing there is no way to do this, other than splitting a clip using FFMPEG, processing the bits, then merging back together ? I can’t seem to find a way to do it as one clip.
