• Anomalie #3016 (Fermé) : imagepalettetotruecolor, double définition (en php 5.5 beta)

  18 juin 2013, par Suske -

  Un user avant-gardiste a ramené un conflit "couldnt declare... already declared".

  La fonction concernée est http://be1.php.net/manual/fr/function.imagepalettetotruecolor.php
  SPIP déclare une fonction du même nom (et de même usage si elle est bien nommée ^^) : http://core.spip.org/projects/spip/repository/entry/spip/ecrire/inc/filtres_images_lib_mini.php#L627

  Bon, je sais pas si php5.5 va rapidement devenir un environnement de production mais comme c’est déjà repéré...

• Revision ccdc448b70 : Remove reset mode_info array per frame The mode_info array was unnecessarily re

  Remove reset mode_info array per frame

  The mode_info array was unnecessarily reset to zero every frame
  when error resilient mode turned on, given that the mode info
  values per block will be assigned during mode search stage.

  This commit removes this reset operation. It reduces the runtime
  cost on memset operation to 1/3. The overall speed -6 runtime is
  reduced by 2%.

• Permission denied with JAVE on OSX

  18 octobre 2016, par clankill3r

  I try to convert video to audio using jave on OSX.

  http://www.sauronsoftware.it/projects/jave/manual.php

  As the documentation states

  ...You can even build it by yourself getting the code (and the
  documentation to build it) on the official ffmpeg site. Once you have
  obtained a ffmpeg executable suitable for your needs, you have to hook
  it in the JAVE library. That’s a plain operation.

  I builded ffmpeg, but running the code I get a Permission denied error.
  I even changed all file permissions to 777 recursive.
  Hope someone can help, the documentation and error messages are very unclear.
