  • Creating farms of unique websites

    13 avril 2011, par

    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" (...)

  • swscale/aarch64 : vscale optimization

    swscale/aarch64 : vscale optimization

    Use scalar times vector multiply accumlate instructions instead of
    
vector times vector to remove the need for replicating load instructions
    
which are slightly slower.

    checkasm : updated tests for sw_scale

    Change the reference to exactly match the C reference in swscale,
    
instead of exactly matching the x86 SIMD implementations (which
    
differs slightly). Test with and without SWS_ACCURATE_RND - if this
    
flag isn't set, the output must match the C reference exactly,
    
otherwise it is allowed to be off by 2.
    

    Mark a couple x86 functions as unavailable when SWS_ACCURATE_RND
    
is set - apparently this discrepancy hasn't been noticed in other
    
exact tests before.
    

    Add a test for yuv2plane1.

  • Is there any library in python or can we use FFMPEG to detect the appearance of the lines pattern in video that is shown in the image attached below ? [closed]

    21 septembre 2022, par Shreyas R

    Video defect appearing frame

    &#xA;

    Hi All,

    &#xA;

    I am trying to find a way to detect the appearance of this lines pattern embedded in the link below.&#xA;If I get any match of this pattern in a video, I need to record that particular timestamp of the video where I got the pattern match.

    &#xA;

    My idea is to take the image and compare it against the video to find for approximate match percentage. If I get it, then I record that particular timestamp within a .txt file.

    &#xA;

    Is there any better way to achieve this ?&#xA;I think we can use Python or FFMPEG video filters to get a solution for this.

    &#xA;

    It would really help if anyone can support with a solution. Thanks

    &#xA;

    Update :&#xA;I got a reference where they have proposed a solution similar to my concern.

    &#xA;

    https://aws.amazon.com/blogs/media/metfc-automatically-compare-two-videos-to-find-common-content/

    &#xA;

    So we can try to achieve some output from this solution.
