  • Récupération d’informations sur le site maître à l’installation d’une instance

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Is there any faster way of synchronize the Drive from Colab

    18 novembre 2018, par jperezmartin

    I need to extract many frames of the videos of one dataset stored in Google Drive from colab code. I mounted drive with

    from google.colab import drive
    
drive.mount('/content/gdrive')

    I am generating and saving the frames with ffmpeg library calling a subprocess.

    subprocess.call(["ffmpeg", "-i", src, dest])

    or

    subprocess.check_call(["ffmpeg", "-i", src, dest])

    The files .jpg are uploaded in drive but not fast. And, at a certain point the synchronization stops, having executed the generation process on the whole dataset in colab.

  • FFMpeg : CFLAGS=-D__STDC_CONSTANT_MACROS ./configure where ?

    24 avril 2013, par olidev

    I got this problem " 'UINT64_C' was not declared in this scope" while using the ffmpeg library for Eclipse running under Ubuntu.

    After a while, I have found this solution : http://code.google.com/p/ffmpegsource/issues/detail?id=11

    But I could not know how to this :

    This should be fixed in our build system no matter what version of ffmpeg you're using. If you're still getting it, run configure like so :
    CFLAGS=-D__STDC_CONSTANT_MACROS ./configure
    and your problems should go away. This applies to other C++ programs using ffmpeg as well and not just to ffms2, but I can't guarantee that other programs won't break if you define that macro (they really shouldn't, though).

    Where can I run the configure ? from Terminal ? I tried with Terminal but it does not work.

    Anybody has an idea how to run the configure ?

    Thanks in advance and your help is much appreciate !

  • How do I batch cut videos ? [closed]

    12 février 2024, par EngineerJack

    I've searched for a while on Google, but haven't found a good solution.

    


    I have multiple videos that I want to cut parts from, so I would like to figure out how to batch cut them so I can figure out each video, then cut them all at once.

    


    I assume I'll use the terminal or powershell, and use commands, write down the info for each video in a file (like a script) then call on that file so they process one after another from that script.

    


    I know that I can do this one-by-one with the code below, but I would like to know how to use the following code for multiple videos as I described above.

    


    ffmpeg -i "video.mp4" -ss 00:00:00 -to 00:00:00 -async 1 -strict -2 "cut.mp4"

    


    BUT, a program (preferrably freeware) that isn't a video editor, but one that I can put the "start" and "end" times, then add multiple videos, WOULD be preferred.

    


    Anyone who can help me with this, I'd appreciate it.

    


    I've tried searching for ways to do this using .bat and .ps1 files on Google, but without finding a good solution.
