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

    26 novembre 2010, par

    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 (...)

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • asm SIMD sniffer

    1er août 2023, par Андрей Тернити

    There is x264.
It use a lot of x86 asm files. For example pixel-32.asm.
This files can use different SIMD instruction set : mmx, 3DNow !, sse family, others

    


    I need the simple way to automatically analyze every file. I want get which SIMD family in which file are used. How ?

    


    I think every asm file must contain information about which SIMD family it use (or information that no SIMD). Without this information it is very bad idea try to use this files...
    
I am angry, my x86 CPU support mmx and 3DNow ! only, but x264 try call sse, so I get "Illegal instruction" sometimes. I plan to make patch for x264.

    


    P.S. If you can make issues in official repo let me know.

    


    P.P.S. This thread on Doom9 (mirror).

    


  • What is the Best Approach for Storing and Displaying Video Files as Base64 in HTML for High Performance and Efficiency ? [closed]

    25 août 2023, par Barthez

    I'm currently working on a project where I need to allow users to upload videos, which will then be converted to Base64 and embedded within an HTML file. I'm reaching out to gain a better understanding of the best practices for accomplishing this task while adhering to Stack Overflow guidelines.Here's my plan so far:Video Upload : Users will be able to upload videos through a web interface.Conversion to Base64 : The uploaded video will be converted to Base64 using [specific library/tool].Embedding in HTML : The Base64 encoded video will be embedded within an HTML file using the tag.Before I proceed, I have a few questions:Are there any particular libraries or tools you recommend for converting videos to Base64 efficiently ?What are the potential performance implications of embedding Base64 videos in HTML files, especially considering large video files ?Are there any security concerns I should be aware of when implementing this process ?How can I ensure cross-browser compatibility when embedding these Base64 videos ?Are there any alternatives to this approach that might be more efficient or manageable ?I want to make sure I'm following best practices and avoiding any pitfalls, so any insights, tips would be greatly appreciated. Thank you for your time and assistance !

    


    I attempted to convert an uploaded video to Base64 and embed it within an HTML file.

    


  • avutil/avutil : make AV_TIME_BASE_Q available in C++

    18 septembre 2023, par Zhao Zhili
    avutil/avutil : make AV_TIME_BASE_Q available in C++

    ISO C++ forbids compound-literals. It's not available with MSVC.
    
This is a known issue from 10 years ago, and that's why there is a
    
av_get_time_base_q().
    

    Since we have no plan to remove AV_TIME_BASE_Q, just make it
    
available in C++.
    

    There are multiple choices :
    
1. Use C++11 syntax : AVRational1, AV_TIME_BASE
    

    Users may still use C++98 to write new code. So no.
    

    2. Use av_get_time_base_q().
    

    It's for this purpose. But it's not compile time constants as
    
AV_TIME_BASE_Q in C.
    

    So I choose av_make_q() as Anton's suggestion.
