  • 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.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible.

  • FFMPEG - latest build doesn't work, earlier build does

    21 juin 2020, par rossmcm

    I have been using FFMPEG to overlay coloured rectangles on a video. I updated FFMPEG and it no longer works. No error is issued, it just doesn't do the job - the resulting video is the same as the input video. Here's the script :

    


    FFMpeg -y -i Input.mp4 -filter_complex \
  "nullsrc=size=1920x1080,  \
  drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow,  fade=in:st=10:d=1:alpha=1, fade=out:st=20:d=2:alpha=1 [tmp1]; \ 
  nullsrc=size=1920x1080,  \
  drawbox=x=240:y=140:w=300:h=150:t=20:c=red,  fade=in:st=15:d=1:alpha=1, fade=out:st=25:d=2:alpha=1 [tmp2]; \
  [tmp1][tmp2] overlay=0:0:shortest=1[tmp3]; \
  [0:v][tmp3] overlay=0:0:shortest=1" \
  Output.mp4


    


    The output video should be the input video with a yellow rectangle added from T=10 to T=20 and a red rectangle from T=15 to T=25, fading them in and out.

    


    The version that was working (3.4) was one that came with an ImageMagick installation. The version I updated it to was 4.2.3. I tried it on various other builds I had lying around and it only works with 3.4.

    


    It seems unlikely that this is a regression so I haven't submitted a bug report. I figure it's more likely that I'm not doing something correctly and 3.4 is more lenient on its interpretation of my command.

    


    Whatever, I prefer to be working with a current build, so I invite comments on what the reasons might be.

    


    Console dump of 3.4 run

  • FFmpeg audio doesnt work in converted videos but in pc it does

    I know there is couple errors tough, but i dont know hot to fix it. Also i would be very thankfull if someone can help reduce video size but is not main problem video weights as original avi but sill.

  • FFMPEG does not add images to audio

    20 février 2018, par Googlebot

    I want to create a slideshow with a background music by ffmpeg, and use the command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

    and map.txt is like

    file '1.jpg'
    
duration 15
    
file '2.jpg'
    
duration 60

    The result is a video with the audio and blank background. If I run the above command without audio as

    ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4

    a perfect video of the images (the intended slideshow) is generated (but obviously without audio).

    I reckon the problem is related to synchronising the audio and images.

    This is the terminal output for the first command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4
