• Evolution #3964 : mise en forme minimum des formulaires

  6 juin 2018, par nico d_

  C’est l’avis de tetue mais pas le mien :)

  Dans cette logique, pour être cohérent jusqu’au bout il faudrait aussi déplacer les h3.legend, .editer, .choix .saisie_* etc, qui sont explicitement liés à spip, dans spip.css
  Et déplacer ce qui reste de margin, font-weight et tous les Elements de notifications des boites succes, info, notice, alerte dans theme.css

  Bref, vider forms.css quoi :)

  Tel que je le conçois, form.css devrait contenir tout le style de base des formulaires spip ainsi que boutons réponses et erreurs.
  Tout dans ce fichier, pour pouvoir facilement le surcharger intégralement.

  Et dans theme.css, les ajustements de marges, couleurs, pour la dist, comme actuellement.

• ffmpeg generate encoded sequence of videos from playlist

  20 janvier 2018, par Massimo Vantaggio

  i use ffmpeg to encode my videos to be ready for mpeg dash process :

  ffmpeg -y -i legend.mp4 -c:a copy -c:v libx264 -x264opts 'keyint=48:min-keyint=48:no-scenecut' -r 24 -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:816" out.mp4

  This command line work fine, and i wonder to know how to create a mp4 encoded file like above from a sequence of videos ?
  I try to get a faster process, and i think that i don’t need to encode separately all videos and after create a sequence (a big video) with post production software.. I wish to resolve all by a sigle command line,
  Is there a way to give a playlist for input to get only one output video within the sequence of the playlist all with the same encoding assuming that all videos have same frame rate and same resolution ?
  Thanks,
  Dan

• Libavcodec "the procedure entry point for av_frame_alloc could not be located" error in Visual Studio 2017 C++ project

  25 novembre 2019, par Aves

  I am trying to use libavcodec from ffmpeg library in C++ with Visual Studio 2017 Community. I downloaded the latest x64 dev and shared builds from zeranoe (version 20171217), set up include directories and additional libraries in Visual Studio for x64 build, added DLL files from shared package to my PATH.

  This is my sample test code :

  extern "C" {
  
  #include 
  
  }
  
  int main() {
  
      avcodec_register_all();
  
      AVFrame *pAvFrame = av_frame_alloc();
  
      av_frame_free(&pAvFrame);
  
      return 0;
  
  }

  The code compiles without problems but when I run the application I see a dialogue window with error message "the procedure entry point for av_frame_alloc could not be located in DLL" (actual message is not in English, this is the translated version).

  I tried to set Linker->Optimization->References to /OPT:NOREF as it was advised in the similar questions but it did not help.

  Dependency walker shows that av_frame_alloc is exported, "Entry Point" is not bound. A little bit strange is that av_frame_alloc is displayed in both avcodec-58.dll (as red) and avutil-56.dll (as green). Maybe the reason is that the application is trying to get this function from avcodec instead of avutil, but I’m not sure, since I did not check the source code of these libraries.

  So the question is how to set up such a simple FFMPEG-based C++ project in VS2017, where I’m wrong ?

  UPD. 1.
