Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -
Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

avutil/avutil : make AV_TIME_BASE_Q available in C++
18 septembre 2023, par Zhao Zhiliavutil/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_BASEUsers 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.

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 BarthezI'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.

asm SIMD sniffer
1er août 2023, par Андрей ТернитиThere 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.
