  • 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 (...)

  • Script timing with FFMPEG and PHP

    I’m running into a very strange bug.

    Here’s my command console output :

    I’ve tried adding sleep(5) after :

           exec($cmd, $out, $ret);

    to give the script time to move the moov atom to the front before uploading the local file to s3 and then deleting the local file, but it is not 100% reliable.

    Any ideas ?

  • ffmpeg : convert FLAC to mp3 and add album art in one step

    19 juillet 2014, par Christian Riedl

    I convert FLAC to MP3 using

    ffmpeg -i x.flac -f mp3 -vn -b:a 64K x.mp3

    and I add album art using

    ffmpeg -i x.mp3 -i x.jpg -map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)" xx.mp3

    Is it possible to do it in one step ? Because I want to do it during "live" transcoding.

  • HTML5 - ffmpeg encoded x264 video fails to play in Chrome/IE

    11 août 2014, par Saren Arterius

    I have totally no idea why http://jiro.wtako.net/video/39 does work in all browsers while http://jiro.wtako.net/video/40 only works in Firefox.

    1 is encoded by MediaCoder (x264 + Nero encoder) and 2 is encoded by Arch Linux ffmpeg.

    ffmpeg version : ffmpeg 1:2.3.1-1

    x264 version : libx264 1:142.20140311-6

    It seems that video size, frame rate, profile, level, bitrate does not affect whether the video can be played, because I have tried all these parameters, none of these works :

    $ ffmpeg -i in.avi -c:v libx264 -crf 25 -pix_fmt yuv420p -preset veryslow -vf scale=640:360 -c:a aac -strict -2 -b:a 192k out.mp4

    $ ffmpeg -i in.avi -c:v libx264 -crf 28 -pix_fmt yuv420p -preset veryslow -c:a aac -strict -2 -b:a 192k out.mp4

    $ ffmpeg -i in.avi -c:v libx264 -crf 28 -pix_fmt yuv420p -level:v 3.2 -preset veryslow -c:a aac -strict -2 -b:a 192k out.mp4

    $ ffmpeg -i in.avi -c:v libx264 -crf 28 -pix_fmt yuv420p -profile:v baseline -preset veryslow -c:a aac -strict -2 -b:a 192k out.mp4
