    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    imgutils : add function to clear an image to black

    Black isn't always just memset(ptr, 0, size). Limited YUV in particular
    
requires relatively non-obvious values, and filling a frame with
    
repeating 0 bytes is disallowed in some contexts. With component sizes
    
larger than 8 or packed YUV, this can become relatively complicated. So
    
having a generic function for this seems helpful.
    

    In order to handle the complex cases in a generic way without destroying
    
performance, this code attempts to compute a black pixel, and then uses
    
that value to clear the image data quickly by using a function like
    
memset.
    

    Common cases like yuv410p10 or rgba can't be handled with a simple
    
memset, so there is some code to fill memory with 2/4/8 byte patterns.
    
For the remaining cases, a generic slow fallback is used.

  • lavfi/tests : Fix 16-bit vf_blend test to avoid memory not aligned to 2 bytes

    lavfi/tests : Fix 16-bit vf_blend test to avoid memory not aligned to 2 bytes

    Generic C implementation of vf_blend performs reads and writes of 16-bit
    
elements, which requires the buffers to be aligned to at least 2-byte
    
boundary.
    

    Also, the change fixes source buffer overrun caused by src_offset being
    
added to to test handling of misaligned buffers.
    

    Fixes : #7226
