  • 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) (...)

    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • HTML5 Video Chrome - ffmpeg - mp4 working in all but Chrome

    16 octobre 2014, par IIIOXIII

    I have successfully encoded a file to .mp4 using ffmpeg which will play in all tested devices (Safari on PC, IE on PC, Android Browser, Andriod Video Player, and Safari iPad), except for Chrome.

    As a work-around, I had planned to simply list the .ogg source prior to the .mp4 source so that chrome would play the .ogg source without even seeing the .mp4 source, however, I ran into the issue mentioned here.

    Basically, I am after the proper ffmpeg command which will encode an .mp4 video to standards which will play in Chrome - of course without losing playback functionality on any of the other previously mentioned platforms.

    I have tried several combinations, such as :

    ffmpeg -i [filename].wmv -vprofile baseline -level 30 -vf scale=640:-1 -movflags faststart [filename].mp4

    etc. but have not yet found the winning one.

    EDIT : I tried :

    ffmpeg_new -i [filename].wmv -strict experimental –acodec libvo_aacenc -ac 2 -ab 160k -vcodec libx264 -vf scale=640:-1 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 [filename].mp4

    And here is the ffmpeg output :

  • Ubuntu 12.04 upgrade php 5.4 missing php5-ffmpeg

    1er juillet 2013, par Lughino

    I updated php to version 5.4 but now I can not install the package php5-ffmpeg because it gives me this error :
    php5-ffmpeg : Depends : phpapi-20090626

    also if I try to write php-v gives me this warning :

    PHP Warning: PHP Startup: Unable to load dynamic library

  • What is wrong with the following ffmpeg command

    What is wrong with the following ffmpeg command. Originally this had -sameq instead of the -qscale:a 0

    Command :

    ffmpeg -loglevel debug -threads 4 -i sample-in.mpg -ss 00:00:01 -t 00:00:05 -f image2 -y sample-frames/frame%d.png -acodec copy -qscale:a 0  -y sample.mp3

    I found the code above from : http://kwlug.org/node/854
    I did a few edits removing the -sameq and replacing it with -qscale:a 0 which probably is wrong.
