  • 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 (...)

  • Match radial lens distortion of two videos taken with two different actioncams with different FOV

    24 mai 2018, par Fabien Biller

    I have two different actioncams with different k1 and k2. How do I calculate k1 and k2 for one video not to be "defished", but have the same amount of distortion as the other video ?

    opusdsp : adjust and optimize C function to match assembly

    The C and asm versions behaved differently _outside_ of the codec.
    

    The C version returned pre-multiplied 'state' for the next execution
    
to use right away, while the assembly version outputted non-multiplied
    
'state' for the next execution to multiply to save instructions.
    
Since the initial state when initialized or seeking is always 0,
    
and since C and asm versions were never mixed, there was no issue.
    

    However, comparing outputs directly in checkasm doesn't work without
    
dividing the initial state by CELT_EMPH_COEFF and multiplying the
    
returned state by CELT_EMPH_COEFF for the assembly function.
    

    Since its actually faster to do this in C as well, copy the behavior the
    
asm versions use. As a reminder, the initial state 0 is divided by
    
CELT_EMPH_COEFF on seek and init (just in case in the future this is
    
changed, its technically more correct to init with CELT_EMPH_COEFF than 0,
    
however when seeking this will result in more audiable pops, unlike with 0
    
where the output gets in sync over a few samples).
