• Fix SWF position and size calculations in IE 9.

  12 juillet 2013, par DelvarWorld

  Fix SWF position and size calculations in IE<9.
  Fixes #190.
  
  Closes #191.
  In oldIE, using the `typeof` operator on native DOM methods like `getBoundingClientRect` actually returns "object" instead of "function".
  
  Also, `getBoundingClientRect` did not add the "height" and "width" properties to TextRectangles until IE9, so calculate those manually if need be.
  Bumped version to v1.2.0-beta.3.
  

• fftools : Use right function signature and pointers

  6 août 2019, par Andreas Rheinhardt

  fftools : Use right function signature and pointers
  The option tables of the various fftools (in particular ffprobe) are
  
  arrays of OptionDef ; said type contains a union of a pointer to void and
  
  a function pointer of type int (*)(void *, const char *, const char *)
  
  as well as a size_t. Some entries (namely the common entry for writing a
  
  report as well as several more of ffprobe's entries) used the pointer to
  
  void to store a pointer to functions of type int (*)(const char *) or
  
  type int (*)(const char *, const char *) ; nevertheless, when the functions
  
  are actually called in write_option (in cmdutils.c), it is done via a
  
  pointer of the first type.
  There are two things wrong here :
  
  1. Pointer to void can be converted to any pointer to incomplete or
  
  object type and back ; but they are nevertheless not completely generic
  
  pointers : There is no provision in the C standard that guarantees their
  
  convertibility with function pointers. C90 lacks a generic function
  
  pointer, C99 made every function pointer a generic function pointer and
  
  still disallows the convertibility with void *.
  
  2. The signature of the called function differs from the signature
  
  of the pointed-to type. This is undefined behaviour in C99 (given that
  
  C90 lacks a way to convert function pointers at all, it doesn't say
  
  anything about such a situation). It only works because none of the
  
  functions this patch is about make any use of their parameters at all.
  Therefore this commit changes the type of the relevant functions
  
  to match the type used for the call and uses the union's function
  
  pointer to store it. This is legal even in C90.

• Unable to convert .mp3 to .m4a using ffmpeg [closed]

  26 décembre 2020, par rahulg

  I am fully aware the legal constraints in using libfaac but this is just for my testing purpose.

  



  I have compiled ffmpeg with faac enabled. So when I tried to convert an .mp3 to a .m4a here is the error that I am getting. Please provide a resolution to this problem. I tried it on two different sources of .mp3, still I am getting the same error.

  MP3 file is at http://db.tt/HtpEBpFU

  



  Also while using Faac independently I get this weird error for any file.
