  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

  • avutil : Add NV24 and NV42 pixel formats

    7 mai 2019, par Philip Langdale
    avutil : Add NV24 and NV42 pixel formats

    These are the 4:4:4 variants of the semi-planar NV12/NV21 formats.
    

    These formats are not used much, so we've never had a reason to add
    
them until now. VDPAU recently added support HEVC 4:4:4 content
    
and when you use the OpenGL interop, the returned surfaces are in
    
NV24 format, so we need the pixel format for media players, even
    
if there's no direct use within ffmpeg.
    

    Separately, there are apparently webcams that use NV24, but I've
    
never seen one.
