    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • 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

    


    Hi All,

    


    I am trying to find a way to detect the appearance of this lines pattern embedded in the link below.
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.

    


    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.

    


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

    


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

    


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

    


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

    


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

    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.

    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.
