  16 septembre 2012, par Yanic Gornet

  l’installation de spip 3.0.5 produit 3 fichiers de log dont deux, spip.log et mysql.log, sont farcis d’erreurs :

  spip.log contient entre 2500 et 2700 lignes dont la plupart sont affectés du mot "ERREUR" voire même du mot "CRITIQUE"

• runtime error when linking ffmpeg libraries in qt creator

  6 juillet 2012, par dxthegreat

  I'm quite new around here but i hear that if you want a question answered, stackoverflow is the place to ask it >.<. So i hope that my question isn't too trivial that everyone will get annoyed at my lack of research (I've tried googling for two days already D= no progress !)
  I've also asked this question in the Qt forums, but i figured i'd ask here too.

  so...

  For the last few days I’ve been fiddling around with opengl and the like, trying to write a video player.

  However, when i try to import the ffmpeg libraries (avcodec, avformat, avutils etc), an error occurs on runtime (the program compiles fine). When compiled and run in debug mode, the error message gives me only a memory address and error code 135 (DLL not found).

  This error occurs when i include a function from those libraries in my code (e.g. av_register_all()) and it occurs regardless of whether the function is actually called.

  So i’m thinking that I’m doing something wrong when linking these libraries.
  I’m currently using :
  Windows vista (32bit),
  Qt creator 2.4.1 based on Qt 4.7.4 (32bit),
  Zeranoe’s FFmpeg build git-3233ad4 (2012-06-30)

  My .pro file consists of :

  QT       += core gui opengl
  
  
  
  TARGET = test
  
  TEMPLATE = app
  
  
  
  
  
  SOURCES += main.cpp\
  
          mainwindow.cpp \
  
      glwidget.cpp
  
  
  
  HEADERS += mainwindow.h \
  
      glwidget.h \
  
  
  
  FORMS    += mainwindow.ui
  
  
  
  
  
  LIBS += -L"$$_PRO_FILE_PWD_/libraries/ffmpeg/libs/" -lavcodec -lavformat -lavutil
  
  INCLUDEPATH += libraries/ffmpeg/includes

  I’ve tried many variations to the LIBS += line and checked my filepath many times. However, the DLL not found error occurs in all of these variations =(.

  Is there something I’m forgetting when doing these includes ?

  Thanks in advance >.<,

• Reload scrolling drawtext filter in ffmpeg only while off screen

  3 janvier 2021, par J45p3r

  I have a drawtext filter in ffmpeg that scrolls right to left on the bottom of the screen showing current weather data. The problem I have is the text file containing the weather data updates every 2 seconds and when the weather readings change the length of the text also changes. This causes the looping text to jump around. I tried using a conditional statement to set reload to 1 only if x was greater than the screen width but it seems reload doesn't evaluate conditional statements. Can anyone think of a way around this problem so that the text will only update once per loop, while off screen ?
