  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • fade In and out effect on a text using ffmpeg in nodejs

    21 septembre 2020, par sankar barman

    There are many examples for command line interface, but what i need is to achieve by having an object property with filter name and options. No solution have been found for this.
Here is the code sample. Everything is working fine, but don't know the syntax for fade In and fade out. Please do help in this. Thanks in advance.

    


    ffmpeg("tmp/" + file.name).videoFilters({ filter: 'drawtext',
options: { 
  fontfile: 'Lucida Grande.ttf',
  x: 50,
  y:20,
  text: 'some title',
  fontsize: '56',
  fontcolor: 'white',
  enable: 'between(t,10,20)'
  fade: ?
}})


    


  • ffmpeg overlay a watermark image on a video every 15 minutes ?

    21 janvier 2016, par Charles

    So I have a snippet from a bash script that overlays a transparent image watermark onto a video file, like this :

    /usr/bin/ffmpeg -i input.mp4 -i out.png -filter_complex "overlay=10:10" /outputfolder/output.mp4

    Works beautifully, and fast.

    What I really need though, is to have the watermark only show up at the start of the video, and then every 15 minutes through the video afterwards, for 30 seconds at a time.

    Is this possible without multiple passes ?

    Thanks in advance for all the help !

  • Scaling seems to crop edges of video

    7 septembre 2020, par Jao

    I'm doing some automation with FFmpeg and I need to be able to scale up and down videos. So I tried using the scale filter. No issue when I'm scaling up but when I'm scaling down I'm losing a few pixels from the bottom of the video and I must keep everything.

    


    Here is an example :

    


    $ ffmpeg.exe -i video.avi -vf scale=1536:644 video_resized.avi


    


    Here, video.avi is 2048x858.
I tried a lot of parameters, algorithms and flags but nothing seems to "fix" it. Maybe it is normal and I'm not understanding correctly how scaling works but I need to resize without loss of edges.
Thanks in advance
