  • lavu/hwcontext_vulkan : support mapping VUYX, P012, and XV36

    lavu/hwcontext_vulkan : support mapping VUYX, P012, and XV36

    If we want to be able to map between VAAPI and Vulkan (to do Vulkan
    
filtering), we need to have matching formats on each side.
    

    The mappings here are not exact. In the same way that P010 is still
    
mapped to full 16 bit formats, P012 has to be mapped that way as well.
    

    Similarly, VUYX has to be mapped to an alpha-equipped format, and XV36
    
has to be mapped to a fully 16bit alpha-equipped format.
    

    While Vulkan seems to fundamentally lack formats with an undefined,
    
but physically present, alpha channel, it has have 10X6 and 12X4
    
formats that you could imagine using for P010, P012 and XV36, but these
    
formats don't support the STORAGE usage flag. Today, hwcontext_vulkan
    
requires all formats to be storable because it wants to be able to use
    
them to create writable images. Until that changes, which might happen,
    
we have to restrict the set of formats we use.
    

    Finally, when mapping a Vulkan image back to vaapi, I observed that
    
the VK_FORMAT_R16G16B16A16_UNORM format we have to use for XV36 going
    
to Vulkan is mapped to Y416 when going to vaapi (which makes sense as
    
it's the exact matching format) so I had to add an entry for it even
    
though we don't use it directly.

  • Make mime-type award a bonus probe score

    21 novembre 2023, par Peter Zebühr
    Make mime-type award a bonus probe score

    This changes the default behaviour of ffmpeg where content-type headers
    
on an input gives an absolut probe score (of 75) to instead give a bonus
    
score (of 30). This gives the probe a better chance to arrive at the
    
correct format by (hopefully) giving a large enough bonus to push edge
    
cases in the right direction (MPEG-PS vs MP3, I am looking at you) while
    
also not adversly punishing clearer cases (raw ADTS marked as
    
"audio/mpeg" for example).
    

    This patch was regression tested against 20 million recent podcast
    
submissions (after content-type propagation was added to
    
original-storage), and 50k Juno vodcasts submissions (dito). No adverse
    
effects observed (but the bonus may still need tweaking if other edge
    
cases are detected in production).

    swscale/utils : Fix color range of gray16

    Improves rgb -> gray16 conversion
    

    Fixes Ticket3422
    

    The pam and png output files look visually similar, in both cases the
    
dynamics increase to 0x0 -> 0xfffb.
