  • 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 (...)

  • avcodec/x86/mpegvideoenc : remove av_assert2() for variable alignment

    avcodec/x86/mpegvideoenc : remove av_assert2() for variable alignment

    It's safe to assume that LOCAL_ALIGNED_16 does indeed align. Otherwise
    
we would have many more problems...
    

    This assert was added in f8188626 all the way back in 2003.

  • gdb not stopping at even trivial breakpoints

    18 novembre 2015, par baruch

    I am trying to debug ffplay (a debug build) compiled using mingw-w64 on msys2 on Windows 7 64bit. I tried setting breakpoints using gdb, and they seem to be set fine, but the program does not stop. So i tried issuing start, and again it didn’t stop. I tried manually setting a breakpoint at main, but it still didn’t stop. I verified that main is found, and it is. Here is a portion of the session. Any explanation what might cause this ?
