  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • Making a video out of frames in Python

    6 juin 2021, par amit

    I have to create a video using earlier extracted frames and the following code works fine :

    


    import os
    
fps = 25

os.system("ffmpeg -r fps -i Encode/encode_image%01d.png -vcodec mpeg4 -y movie.mp4")


    


    But storing framerate (which is 25 in this case) in fps variable and passing it in -r, I am getting following error :

    


    


    "Error parsing framerate fps."

    


    


    Meanwhile, the code below, creates a video :

    


    import os

fps = 25
os.system("ffmpeg -r 25 -i Encode/encode_image%01d.png -vcodec mpeg4 -y movie.mp4")


    


    But the framerate is different for every one of my videos (that's why I am storing it in a variable).
Due to above error I am unable to pass different frame rate value each time and, I cannot type the value (like 25) directly.

    


    Please suggest me some way to tackle this problem or provide me with another Python code to combine frames into video.

  • Making a movie from the url using ffmpeg and phantomjs

    1er novembre 2016, par Matt

    Im Taking screen shots from a url, using phantomjs using the setIntreval function (25 right now) and then piping the output to the ffmpeg (Using the frame rate -r 24).
    Here is the Code. ffmpeg.js

    var page = require('webpage').create();
    
page.viewportSize = { width: 1024, height: 768 };
    

    
page.open('http://ewoken.github.io/Leaflet.MovingMarker/', function () {
    
  setInterval(function() {
    
    page.render('/dev/stdout', { format: "png" });
    
  }, 25);
    
});

    Then I run the script using this.

    phantomjs ffmpeg.js | ffmpeg -y -c:v png -f image2pipe -r 24 -t 10 -i - -c:v libx264 -pix_fmt yuv420p -movflags +faststart output.mp4

    Like In the command Im getting the 10 sec video with the page, But Its all speeding up fast first and completely freezes with a last frame.

    Can you guys help me, with a work around, enabling me to record the page , AS IS ? Like if there is a 3000 delay animation in the movie, It should appear like real in the movie, like smooth and in real time.

    Thank you guys. Stuck on this for a long time now.

    Cheers,
