  • {avcodec,tests} : rename the bundled Mesa AV1 vulkan video headers

    14 février 2024, par Jan Ekström
    avcodec,tests : rename the bundled Mesa AV1 vulkan video headers

    This together with adjusting the inclusion define allows for the
    
build to not fail with latest Vulkan-Headers that contain the
    
stabilized Vulkan AV1 decoding definitions.
    

    Compilation fails currently as the AV1 header is getting included
    
via hwcontext_vulkan.h -> <vulkan/vulkan.h> -> vulkan_core.h, which
    
finally includes vk_video/vulkan_video_codec_av1std.h and the decode
    
header, leading to the bundled header to never defining anything
    
due to the inclusion define being the same.
    

    This fix is imperfect, as it leads to additional re-definition
    
warnings for things such as
    
VK_STD_VULKAN_VIDEO_CODEC_AV1_DECODE_SPEC_VERSION. , but it is
    
not clear how to otherwise have the bundled version trump the
    
actually standardized one for a short-term compilation fix.

  • FFMPEG - 4K HDR - MPEG - BIG FILE convert

    8 mars 2018, par Ian Lodanko

    I would like to ask how through ffmpeg to achieve the smallest file size and yet keep the best quality [LIKE Youtube convert].

    Currently used :

    ffmpeg -i "/home/sampe_4K_HDR.mkv" -map 0:00 -c:v libx264 -preset ultrafast -b:v 66718k -pix_fmt yuv420p10le -x264-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc" -crf 18 -c:a libfdk_aac -profile:v baseline -level 3.0 "/home/sampe_4K_HDR.mp4"

    But the size of the video after conversion is very large, I would like to preserve as much as possible the quality of the original video and get the smallest possible video size.

    Could you please advise ? Write some examples of how to get better with smaller sizes ? Thank you in advance and I apologize for my English in advance.
