• Anomalie #3889 (Nouveau) : Vignettes de documents erronées dans les résultats de recherche de l’es...

  17 janvier 2017, par Valéry -

  On me signale que sur un site en SPIP 3.1.3 lorsque l’on fait une recherche dans le backoffice, le premier résultat trouvé dans les Documents affiche toujours la même photo en miniature, quelle que soit la recherche. Cette miniature ne correspond pas au document lui-même.

  J’ai reproduit un comportement différent mais également erroné sur un autre site en SPIP 3.1.3.

  Les résultats de la recherche dans l’espace privé ?exec=recherche affichent uen liste des documents trouvés accompagnés parfois d’une vignette qui n’est pas celle du document (en l’espèce ce sont des logos d’articles qui n’ont rien à faire là).

• ffmpeg x11grab Fedora 22 cannot open display [on hold]

  4 août 2015, par voor

  Running a fairly recent version of Fedora 22 :

  Dual screen Acer XB270HU and AOC 2369. Also uses NVIDIA Drivers :

  Whenever I attempt to do a x11grab in ffmpeg I get an error :

  I’ve tried a few different commands basically copy/pasta from the web on how to do screengrabs. I don’t need audio, just video, and all of them result in the same error.

  I am able to do xwininfo without any problems :

• FFMpeg mp4 to mp4 codec switching failing

  31 juillet 2015, par Cory Lineberger

  Ok so sorry from the beginning if this is a newb question or if it is in the wrong place, this IS my first question on here.

  So I record things that save files in an mp4 container, I am unsure of the exact codecs it uses, but I know the video codec is not libx264, because if it was Premier would accept it. The audio on Premier works fine. But the video doesn’t. It says that it is an only audio file, but when I play it in, say, Windows Media Player, both the audio and video work fine. The line of copy I am trying to use (in a .bat, if that helps) is :

  @ECHO OFF
  
  for %%a in (*.mp4) do ffmpeg -i "%%a" -c:v libx264 -preset ultrafast -qp 10 -c:a copy -y "%%~na".mp4

  I have very little experience with this...... stuff. I should go ahead and mention, I am running Windows 10. In Windows 7 I used a different program that recorded AVI files that used an invalid video codec for Premier. But this .bat code worked to convert those.

  @ECHO OFF
  
  for %%a in (*.avi) do ffmpeg -i "%%a" -c:v libx264 -preset ultrafast -qp 10 -f mp4 -y "%%~na".mp4

  So I figured just changing some stuff would work, but I guess not.

  EDIT : Speaking of being my first question I forgot to put the problem !
  The problem is that it DOES convert it, but it converts 5 seconds of a 40+ min video and then exits out.
