  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.
    While using MediaSPIP, you are invited to avoid using words like "Brand", "Cloud" and "Market".
    MediaSPIP is designed to facilitate the sharing of creative media online, while allowing authors to retain complete control of their work.
    MediaSPIP aims to be accessible to as many people as possible and development is based on expanding the (...)

  • avformat/mxfdec : Don't use wrong type of pointer

    avformat/mxfdec : Don't use wrong type of pointer

    If one of the two results of a ternary conditional is a pointer to void,
    
the type of the whole conditional operator is a pointer to void, even
    
when the other possible result is not a pointer to void. This loophole
    
in the type system has allowed mxf_read_local_tags to have a pointer of
    
type pointer to MXFMetadataSet that actually points to an MXFContext.

  • swscale/vscale : Increase type strictness

    26 avril 2020, par Andreas Rheinhardt
    swscale/vscale : Increase type strictness

    libswscale/vscale.c makes extensive use of function pointers and in
    
doing so it converts these function pointers to and from a pointer to
    
void. Yet this is actually against the C standard :
    
C90 only guarantees that one can convert a pointer to any incomplete
    
type or object type to void* and back with the result comparing equal
    
to the original which makes pointers to void generic pointers to
    
incomplete or object type. Yet C90 lacks a generic function pointer
    
type.
    
C99 additionally guarantees that a pointer to a function of one type may
    
be converted to a pointer to a function of another type with the result
    
and the original comparing equal when converting back.
    
This makes any function pointer type a generic function pointer type.
    
Yet even this does not make pointers to void generic function pointers.
    

    Both GCC and Clang emit warnings for this when in pedantic mode.
    

    This commit fixes this by using a union that can hold one member of any
    
of the required function pointer types to store the function pointer.
    
This works even for C90.

  • Icecast : always send a content-type

    11 novembre 2014, par Marvin Scholz
    Icecast : always send a content-type

    use a default (audio/mpeg for historical reason) if none. Required since Icecast 2.4.1
    
Not using AVOption default because this breaks content-type warnings (needs to
    
detect if no type was set by the user)
