  • 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 (...)

  • 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 (...)

  • avutil/x86/pixelutils : Empty MMX state in ff_pixelutils_sad_8x8_mmxext

    1er novembre 2023, par Andreas Rheinhardt
    avutil/x86/pixelutils : Empty MMX state in ff_pixelutils_sad_8x8_mmxext

    We currently mostly do not empty the MMX state in our MMX
    
DSP functions ; instead we only do so before code that might
    
be using x87 code. This is a violation of the System V i386 ABI
    
(and maybe of other ABIs, too) :
    
"The CPU shall be in x87 mode upon entry to a function. Therefore,
    
every function that uses the MMX registers is required to issue an
    
emms or femms instruction after using MMX registers, before returning
    
or calling another function." (See 2.2.1 in [1])
    
This patch does not intend to change all these functions to abide
    
by the ABI ; it only does so for ff_pixelutils_sad_8x8_mmxext, as this
    
function can by called by external users, because it is exported
    
via the pixelutils API. Without this, the following fragment will
    
assert (on x86/x64) :
    
    uint8_t src1[8 * 8], src2[8 * 8] ;
    
    av_pixelutils_sad_fn fn = av_pixelutils_get_sad_fn(3, 3, 0, NULL) ;
    
    fn(src1, 8, src2, 8) ;
    
    av_assert0_fpu() ;

    ffools/ffmpeg_filter : stop trying to handle an unreachable state

    ifilter_send_eof() will fail if the input has no real or fallback
    
parameters, so there is no need to handle the case of some inputs being
    
in EOF state yet having no parameters.

  • avcodec/vvc_parser : Don't store state unnecessarily

    29 juin 2023, par Andreas Rheinhardt
    avcodec/vvc_parser : Don't store state unnecessarily

    VVCParserContext.au_info is only used once (and in a read-only manner) ;
    
but this happens immediately after au_info has been completely
    
overwritten. Therefore one can just the src structure used to overwrite
    
au_info directly and remove au_info.
    

    This also means that the whole referencing and unreferncing of au_info
    
(which duplicates AVBufferRefs CodedBitstreamH266Context and is
    
therefore of dubious gain) can be removed, as can the AVBufferRef*
    
contained in PuInfo ; this also removes a certain uglyness : Sometimes
    
these AVBufferRef* were ownership pointers and sometimes not.
