• libopenjpegenc : fix out-of-bounds reads when filling the edges

  libopenjpegenc : fix out-of-bounds reads when filling the edges
  The calculation of width/height should round up, not round down to
  
  prevent setting width or height to 0.
  Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
  
  calculation could silently wrap around without the explicit cast to int.

    swscale : Convert the check check_image_pointers helper to a macro
  [14:52:50] <jamrial> michaelni, ubitux : 37f573543c yay or nay ? we don't have the warnings mentioned there because we cast the argument
  
  [14:54:10] <@ubitux> i don't really see the improvement, no opinion
  
  [15:04:14] <michaelni> jamrial, functions are better/cleaner than macros
  
  [15:04:20] <michaelni> IMHO that is

  make: *** [ffmpeg_movie.lo] Error 1

  this is what i have execute

  #  git clone https://github.com/tony2001/ffmpeg-php.git
  
  #  cd ffmpeg-php
  
  #  make clean
  
  #  phpize 
  
  #  ./configure 
  
  #  make

  when i search for a solution i found this :
  If you get an error message like make : *** [ffmpeg_movie.lo] Error 1 open the ffmpeg_movie.c file and make the following changes :

  user@myVPS:~# vim ffmpeg_movie.c

  Change list_entry *le ; to zend_rsrc_list_entry *le ;
  Change list_entry new_le ; to zend_rsrc_list_entry new_le ;
  Change hashkey_length+1, (void *)&new_le, sizeof(list_entry), to hashkey_length+1, (void *)&new_le,sizeof(zend_rsrc_list_entry),

  but when i check the ffmpeg_movie.c i found that is already fixed with this changes.
  I can’t find the probleme
