  • 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 (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • lavf/rtpenc_jpeg : Retrieve sampling factor from SOF0

    11 janvier 2023, par Yeoh, Hoong Tee
    lavf/rtpenc_jpeg : Retrieve sampling factor from SOF0

    In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and
    
color-range parsed in. There is limitation on current design
    
where need to include support newly introduced PIX_FMT such as
    
AV_PIX_FMT_QSV and there might be more and more in future. Hence,
    
retrive the sampling factor from SOF0 in JPEG compressed header
    
directly. This introduces flexibility to handle different type of
    
new codec introduced in future.

  • lavc/bswapdsp : purge RISC-V V bswap32

    lavc/bswapdsp : purge RISC-V V bswap32

    This cannot beat the Zbb implementation, and it is unlikely that a real
    
meaningful CPU design would support V and not Zbb. The best loop rewrite
    
that I could come up with (4 shifts, 2 ands, 3 ors) is still 40% slower
    
than Zbb.
    

    A proper faster vector implementation should be feasible with the
    
cryptographic vector extensions, but that is a story for another time.

  • avutil : add thread executor

    29 août 2023, par Nuo Mi
    avutil : add thread executor

    The executor design pattern was introduced by java
    
<https://docs.oracle.com/en/java/javase/20/docs/api/java.base/java/util/concurrent/Executor.html> ;
    
it also adapted by python
    
<https://docs.python.org/3/library/concurrent.futures.html> ;
    
Compared to handcrafted thread pool management, it greatly simplifies the thread code.
