  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • How to speed up sound and video and modify the pitch ?

    3 août 2020, par DiREKT

    I want to increase speed on both the sound and the video, while adding pitch to the audio alone.

    


    I have those two ffmpeg commands, but I don't know how to make them work together.

    


    ffmpeg -i input.mkv -filter_complex "[0:v]setpts=0.94*PTS[v];[0:a]atempo=1.06[a]" -map "[v]" -map "[a]" output.mkv


    


    and

    


    ffmpeg -i input.mkv -filter:a "atempo=1.06,asetrate=44100*1.25" output.mkv


    


  • FFmpeg make video from figures and speed up a chosen part

    11 juin 2020, par user13720066

    Make a video from a series of 100 figures

    



    ffmpeg -framerate 10 -i input_figure%01d.png out.mp4


    



    How can I only make figure numbers from [0-49] with a slower speed like -framerate 5 ?

    



    My try is

    



    ffmpeg -start_number 1 -framerate 5 -i input_figure%01d.png -vframes 49 \
-start_number 50 -framerate 10 -i input_figure%01d.png \
out.mp4 


    



    Doesn't work

    


  • FFMPEG stuck at 00:00:00 speed=0x for a long time at the beginning

    4 juin 2020, par lagmoellertim

    I'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.

    



    Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.

    



    The input file for all these separate parts is always the original 1.5h video clip.

    



    The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :

    



    frame=    0 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

    



    Here is the ffmpeg script I use

    



    ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4

    



    I also tried adding -ss 00:24:00 before or behind the -i input, but I did not notice any speed improvement.

    



    And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :
