• Anomalie #3884 (Nouveau) : réintegrer le remplissage de spip_types_documents dans le core

  30 décembre 2016, par Maïeul Rouquette

  Pour le moment le remplissage de la table spip_types_documents se trouve dans@ plugins-dist/medias@.

  Mais on appelle cette table dans le core à certains endroits, par exemple dans inc/acces.php, inc/distant.php etc.

  Il me semble qu’il faudrait distinguer :
  - medias qui se charge des document
  - du core, qui fournit des informations de sécurité relatif aux types de documents

  Pour le moment cela ne pose pas probléme, parce que medias est dans les plugins dist, mais le jour où on aura des distrib différentes, ce serait pas mal.

• Evolution #3039 : Spip 2.1 : prise en compte des champs_extra dans editer_artcile

  16 juillet 2014, par b b

  Salut,

  Tu utilises bien le plugin champs extras, as-tu posé ta question dans le forum du plugin en question sur contrib ?

  Pour info, j’ai fermé ce ticket car les champs extras ne sont plus gérés par le core, mais par le plugin éponyme, cf :

  Le support des champs extra n’est plus natif à partir de SPIP 2.0.

  http://contrib.spip.net/Champs-Extra,2939

  Voilà pourquoi je pense que ce ticket est invalide (sans rapport avec le core).

• Solving The XVD Puzzle

  15 avril 2012, par Multimedia Mike — General, multimedi archaeology, silicon valley, vg2, xvd, zygo

  I downloaded a multimedia file a long time ago (at least, I strongly suspected it was a multimedia file which is why I downloaded it). It went by the name of ‘lamborghini_850kbps.vg2′. I have had it in my collection for at least 7 years. I couldn’t remember where I found it. I downloaded it before it occurred to me to take notes about this sort of stuff.

  I found myself staring at the file again today and Googled the filename. This led me to a few Japanese sites which also contained working URLs for a few more .vg2 samples. Some other clues led me to a Russian language forum where someone had linked to a site that had Win32 codec modules that could process the files. The site was defunct but the Internet Archive Wayback Machine kept a copy for me, as well as copies of several more .vg2 samples from a defunct Japanese site previously involved with this codec.

  Sometimes this internet technology works really well. But I digress.

  Anyway, through all this, I finally found a clue : XVD. and wouldn’t you know, there is already a basic page on the MultimediaWiki describing the technology. In fact, while VG2 is a custom container, the MultimediaWiki states that the video component has a FourCC of VGMV, and there is already a file named VGMV.avi in the root V-codecs/ samples directory, something I vow to correct (that’s a big pet peeve of mine– putting samples in the root V-codecs/ or A-codecs/ directories).

  XVD… XVD… XVD… why does that sound so familiar ? Oh, of course ; there is a company named XVD and they have an office in the Bay Area which I have passed on numerous occasions, like this morning :

  Someone originally connected with the multimedia technology in question operates a website which contains an unofficial history of the XVD tech. At first, I was wondering if the technology was completely defunct (and should therefore be open sourced). But if XVD’s solutions page (dated 2010) is to be believed, the technology is still in service, and purported to be better than H.264 and VC-1 : “The current generation of XVD video compression technology provides better video quality at any given data rate than standards-based codecs (H.264 or VC-1) with four times lower encoding complexity (when compared with H.264 Main Profile).”

  If they say so. For my part, I’m just happy that I have finally figured out what this lamborghini_850kbps.vg2 is so that I can properly catalog it on the samples site, which I have now done, along with other samples and various codecs modules.

  This episode reminds me that there’s a branch office of Zygo Corporation close to my home (though the headquarters are far, far away). The companies you see in Silicon Valley. Anyway, long-time open source multimedia hackers will no doubt recognize Zygo from the ZyGo FourCC & video codec transported in QuickTime files that was almost decode-able using an H.263 decoder.

  
  
  

  I may never learn what Zygo’s core competency actually is, but I will always remember their multimedia tech every time I run past their office.
