  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • How to encode and segment at the same time ?

    18 octobre 2011, par lvreiny

    I want to implement HTTP streaming server, which is similar to this (http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/)
    But, instead of segment the video file after it is completely converted by ffmpeg, I want to do encoding and segmenting at the same time (something like if the output stream from the encoder is sent to the segmenter immediately).

    Thanks

  • using FFMPEG to convert to MP4 with maximum browsers compatibilty

    6 mars 2016, par Karim

    I’m converting from WMV to FLV using FFMPEG, and my problem is that the FLV videos are so big ! the 15 minutes video’s size ranges between 150MB and 1GB !
    I’m using the following FFMPEG command to convert and split WMV videos :

    nohup nice -1 ffmpeg -y -ss 00:00:00 -t 00:15:00 -async 1 -i INPUT.WMV -acodec libmp3lame OUTPUT.FLV

    And I’ve tried converting to MP4 before and the video size was much smaller than the FLV video.

    So my questions are :

    • Would the MP4 videos have any
      compatibility issues browsers ?
    • Would it work on iPhone, iPad ? (I
      know FLV videos doesn’t work on
      iPhones or iPads)
    • What is the best FFMPEG command to
      convert to MP4 without losing the
      quality of the video ?
