• Anomalie #4451 : Espace privé : une recherche ne renvoie jamais de résultat sur un groupe de mots

  3 mars 2020, par Peet du

  C’est certainement du au fait que les groupes font exception par rapport aux autres objets car ils ne disposent pas de page de "vue"

  Oui pour gérer les groupes de mots, pas besoin d’un tableau "liste des groupes de mots". Ça marche très bien comme ça. Et c’est aussi probablement la raison de cet oubli.

  Parce que pour la gestion de la recherche, il me semble qu’il y a bien des cas où cela peut être utile.

  J’insiste (un peu) pour le faire dans la 3.3 (avec report sur la 3.2 ?) :

  1. c’est utile et pas grand chose à faire ;
  2. c’est cohérent : pourquoi on trouve des résultats sur tous les objets SPIP mais pas celui-là ? ;
  3. je test mon fork depuis qqs jours et je ne vois toujours pas d’effet de bord indésirable ;
  4. ce sera fait (corolaire de 1. :-)

  Dernier point : j’ai ajouté dans mon fichier /liste/groupes_mots.html un #REM avec la mention : Ce squelette n’est utile que pour l’affichage éventuel de résultats du moteur de recherche de l’espace privé

  Tell me…

• Is there a set of working P/Invoke declarations for FFMpeg, libavutil, libavformat and libavcodec in .NET ?

  11 février 2014, par casperOne

  I'm currently looking to access libavutil, libavformat and libavcodec (all part of FFMpeg) from .NET.

  Currently, I'm getting the libraries from the automated builds of the shared FFMpeg package performed every night for Windows 32-bit.

  I am also using the code from the ffmpeg-sharp project. In that project, I have removed a number of classes that were not compiling (they are wrapper classes not the P/Invoke declarations).

  The code compiles fine, but I am running into a few issues.

  First, it appears that the build of av*.dll uses the cdecl calling convention, as I was receiving a number of PInvokeStackImbalanceException when trying to call av_open_input_file. This was easy enough to change to get it to work right. The AVFormatContext structure is populated.

  After that, I want to call av_find_stream_info to get information about the streams in the file. However, when calling that with the AVFormatContext retrieved from the call to av_open_input_file, an AccessViolationException is thrown indicating that I am trying to read or write from protected memory.

  Has anyone used P/Invoke to access the libavutil, libavformat and libavcodec dll libraries through P/Invoke and have gotten it to work ?

  I should mention that working with the command-line version of FFMpeg, while a solution, is not a viable solution in this case, access needs to occur through the libraries. The reason for this is that I'd have to thrash the disk way too much to do what I need to do (I have to do a frame-by-frame analysis of some very high definition video) and I want to avoid the disk as much as possible.
