  • 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

  • movenc : Write a 0 duration in mdhd and tkhd for an empty initial moov

    movenc : Write a 0 duration in mdhd and tkhd for an empty initial moov

    ISO/IEC 14496-12:2012/Cor 1:2013 is explicit about how this should be
    
handled. All zeros doesn’t mean that the full file has got a zero
    
duration, only that the track samples described within the initial moov
    
have got zero duration. An all ones duration means an indeterminate
    
duration.
    

    Keep writing a duration consisting of all ones for the ISM mode -
    
older windows media player versions won’t play a file if this is
    
zero. (Newer windows media player versions play either version fine.)

  • movenc : Add a flag for using default-base-is-moof in tfhd atoms

    29 octobre 2014, par Martin Storsjö
    movenc : Add a flag for using default-base-is-moof in tfhd atoms

    Similarly to the omit_tfhd_offset flag added in e7bf085b, this
    
avoids writing absolute byte positions to the file, making them
    
more easily streamable.
    

    This is a new feature from 14496-12:2012, so application support
    
isn’t necessarily too widespread yet (support for it in libav was
    
added in 20f95f21f in July 2014).

  • Create webm from consecutive snapshots

    22 octobre 2014, par camb8

    How can I create a webm stream (to use with a video tag in a web application) from consecutive snapshots ? (on linux)

    I understand that I can do this be creating a streaming server using ffserver and providing a intup stream to the server (tutorial here) using ffmpeg.

    The snapshots can be obtained from a ip camera using it’s snapshot cgi (’http://ipaddress/snapshot.cgi’)

    I found this and this but both of them use files and not a url to provide input images.
