  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Need help to remove repetitions or duplicated frams in my podcast videos

    19 décembre 2020, par Måns Bredelius

    I record videos in a strange way. When I record my podcast videos I often record in the same conversation twice within the same video.

    


    If you would look at it you would see and hear something like this.

    


    "I open the door I open the door and let him in".

    


    I open the door was recorded twice in this example. Currently, I am manually removing these things myself in DaVinci resolve afterward. But I have heard that FFMPEG and mpdecimate are things that could do some wonders here.

    


    I found a video on youtube and found this code
ffmpeg -i original_file.mp4 -vf mpdecimate -vsync vfr -acodec copy mpdecimated.mp4

    


    but nothing happened. Something did happen, it did do something, but nothing happened to my video.

    


    Would love some help.

    


  • Uploading & Processing Videos in Rails app on Heroku

    8 octobre 2015, par scientiffic

    In my Rails app, users can upload videos. The videos need to get converted to mp4s to ensure they can play across browsers, and they are hosted on AWS S3.

    If the video conversion (using ffmpeg) happens quickly, the resulting mp4 is rendered directly on the page so the user can immediately view the uploaded video. Sometimes, though the conversion takes long enough that I get Heroku H12 errors (request timeout), which prevents the video preview from appearing.

    Is there a recommended workflow for dealing with processing larger files in a Rails app using Heroku ?

    The option that immediately comes to mind is processing in a background task using something like Sidekiq, but then the user doesn’t receive feedback when the upload is complete.

  • Stream Multiple Videos Using FFMPEG

    21 août 2020, par Devin Dixon

    I am currently streaming videos as such :

    


    


    ffmpeg -re -i video.mp4 -maxrate 3000k -bufsize 6000k -c:v libx264
-preset superfast -tune zerolatency -strict -2 -c:a aac -ar 44100 -f flv rtmp::locahost/live/123

    


    


    Let's say I have video1.mp4, video2.mp4, video3.mp4. Each might have a different resolution.

    


    Is there a way to stream them one right after each other in one command ?
