• ffmpeg : Fix memset size on ctts_data in mov_read_trun() (round 2)

  ffmpeg : Fix memset size on ctts_data in mov_read_trun() (round 2)
  The allocated size of sc->ctts_data is
  
  (st->nb_index_entries + entries) * sizeof(*sc->ctts_data).
  The size to memset at offset sc->ctts_data + sc->ctts_count should be
  
  (st->nb_index_entries + entries - sc->ctts_count) *
  
  sizeof(*sc->ctts_data))
  The current code missed |entries| I believe, which was introduced in
  
  https://patchwork.ffmpeg.org/patch/5541/.
  However, after offline discussion, it seems the original code is much
  
  more clear to read (before https://patchwork.ffmpeg.org/patch/5541/).
  Hence this CL revert the memset logic to it's previous state by
  
  remembering the |old_ctts_allocated_size|, and only memset the newly
  
  allocated entries.
