• lavf/dashenc : Fix segment duration overflow on fine time bases.

  20 novembre 2018, par Andrey Semashev

  lavf/dashenc : Fix segment duration overflow on fine time bases.
  When stream time bases are very fine grained (e.g. nanoseconds), 32-bit
  
  segment duration may overflow for even for rather small segment duration
  
  (about 4 seconds long). Therefore we use 64-bit values for segment duration.

• lavfi/vf_drawtext : fix memory management when destroying font face

  31 octobre 2024, par Leandro Santiago

  lavfi/vf_drawtext : fix memory management when destroying font face
  Ref https://trac.ffmpeg.org/ticket/11152
  According to harfbuzz docs, hb_ft_font_set_funcs() does not need to be
  
  called, as, quoted :
  ```
  
  An #hb_font_t object created with hb_ft_font_create()
  
  is preconfigured for FreeType font functions and does not
  
  require this function to be used.
  
  ```
  Using this function seems to cause memory management issues between
  
  harfbuzz and freetype, and could be eliminated.
  This commit also call hb_ft_font_changed() when the underlying FC_Face
  
  changes size, as stated on hardbuzz :
  ```
  
  HarfBuzz also provides a utility function called hb_ft_font_changed() that you should call
  
  whenever you have altered the properties of your underlying FT_Face, as well as a hb_ft_get_face()
  
  that you can call on an hb_font_t font object to fetch its underlying FT_Face.
  
  ```
  Finally, the execution order between hb_font_destroy() and
  
  hb_buffer_destroy() is flipped to match the order of creation of
  
  the respective objects.
