  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg : getting larger gif file after optimization [closed]

    28 août 2024, par xaxa

    I'm trying to use ffmpeg to reduce the size of GIF images by lowering fps and color palette size. This is the command I use :

    


    ffmpeg -i initial.gif -filter_complex "[0]fps=${fps},split[m][t];[t]palettegen=max_colors=${max_colors}[p];[m][p]paletteuse" output.gif


    


    however, for some reason I'm getting larger files even if I do something as stupid as fps=1, max_colors=4.

    


    here's the initial file :
enter image description here

    


    here's what I've got after the transformation :
enter image description here

    


    the command was :

    


    ffmpeg -i eglite.gif -filter_complex "[0]fps=1,split[m][t];[t]palettegen=max_colors=4[p];[m][p]paletteuse" output.gif


    


    and the sizes I get are :

    I send video stream from mobile app over rtmp encoded with hevc to my laptop where running script ffmpeg -f flv -listen 1 -i rtmp://192.168.0.194/s/streamKey -c:v libsvtav1 -f mpegts srt://192.168.0.167:9998?mode=caller. On the desktop i have obs with media source input srt://192.168.0.167:9998?mode=listener.

    


    When i run ffmpeg script without video codec option (-c:v libsvtav1) its working fine and in obs i can see video from my phone camera. With the option i can not see video only audio.
I clearly dont understand warning message : [mpegts @ 0x55ec921d9540] Stream 0, codec av1, is muxed as a private data stream and may not be recognized upon reading..
Do I need specify codec (av1) in obs media source or my ffmpeg script is wrong ?
