    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) (...)

  • 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 (...)

  • FFMPEG library | C/C++ | unstable sample count in decoded audio

    6 novembre 2024, par Arthur Llew

    I'm currently learning to use FFMPEG library for my small C++ project. One thing I've noticed while decoding .mp3, .ogg is that frame->nb_samples (AVFrame *frame) starts to flicker on the last several frames. For example, frame consistently had 1024 or 1152 samples but last 4-5 frames have 400-800 samples. This also depends of the file decoder is reading.

    


    According to this thread this might some sort of padding. Is there a way to verify the frame actually contains useful data (other than checking frame->nb_samples with some fixed value) ?

    


  • Install ffmpeg php on heroku and store files on AWS S3

    14 février 2018, par eneneharrison

    I run a php application on heroku and I store my files on AWS S3.
    I would like to upload an audio file in any file format and convert it into .mp3
    file using ffmpeg.

    How do I install ffmpeg on heroku ?
    How do I write the code to upload the newly converted audio file to AWS S3 ?

    I will appreciate any code snippets or a link to an online resource for further research.

    Thank you all.

  • Video length missing in FLV converted by ffmpeg-php

    19 janvier 2013, par Andrew

    I'm converting MP4 videos to FLV using ffmpeg-php on my CentOS server (without intervention from flvtool2 because it's not installed).

    The FLV videos are created, but no player is capable of retrieving the video duration, this creates serious issues when trying to seek the video. I'm using the player created by Moyea's Flash Video MX Pro, but the problem also happens with other FLV players as well, so I'm sure that ffmpeg-php is not createing the FLV with the proper length data.

    My MP4 videos are compatible because ffmpeg-php CAN get the video length properly from then, yet it does not apply that length information into the FLV file. I assume flvtool2 is ONLY to retrieve meta-data and has nothing to do with the output FLV video length, let me know if this is correct.

    This command I use for conversion :

    $command = "ffmpeg -i myvideo.mp4 -ar 22050 -ab 64k -f flv -s 320x240 -y myvideo.flv";
    
$result = @shell_exec($command);

    This is my ffmpeg-php version :
