  • avutil/film_grain_params : add metadata to common struct

    avutil/film_grain_params : add metadata to common struct

    This is needed for AV1 film grain as well, when using AFGS1 streams.
    
Also add extra width/height and subsampling information, which AFGS1
    
cares about, as part of the same API bump. (And in principle, H274
    
should also expose this information, since it is needed downstream to
    
correctly adjust the chroma grain frequency to the subsampling ratio)
    

    Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI,
    
add the new fields after the union ; but with enough of a paper trail to
    
hopefully re-order them on the next bump.

  • lavc/vulkan : add SPIR-V compilation support

    lavc/vulkan : add SPIR-V compilation support

    This is the same as with libavfilter.
    

    We will need SPIR-V compilation for at least three different things,
    
like the VC-2 encoder and decoder, AV1 film grain synthesis for
    
hardware with no support for it, and possibly other codecs.

  • libdav1d : update API usage to the first stable release

    11 décembre 2018, par James Almer
    libdav1d : update API usage to the first stable release

    The color fields were moved to another struct, and a way to propagate
    
timestamps and other input metadata was introduced, so the packet
    
fifo can be removed.
    

    Add support for 12bit streams, an option to disable film grain, and
    
read the profile from the sequence header referenced by the ouput
    
picture instead of guessing based on output pix_fmt.
