• Intel QuickSync error : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  30 novembre 2018, par Arie Syamsudin

  I want to make IPTV with a topology like this :

  Restream / source -----> IPTV server -----> User

  The problem at the moment is the question of bandwidth that is still large.

  Finally I announced by IPTV software providers to transcode with Intel QuickSync video and FFmpeg.

  I followed the steps given by the software provider at the following link :
  http://www.ezhometech.com/document/intel_ffmpeg.txt

  Which comes from the link below :
  https://www.intel.com/content/dam/www/public/us/en/documents/white-paper...

  I installed IPTV software on a laptop with an Intel processor, chipset and VGA.

  avcodec/aacsbr_template : Remove pointless runtime initialization
  The sbr_qmf_window_us array is basically symmetric around its middle
  
  element and therefore the latter half is currently initialized from the
  
  first half at runtime. Yet because the first half is initialized, the
  
  array can't be placed in .bss at all, so that one gains nothing from not
  
  already initializing the whole array statically. Therefore this commit
  
  does exactly this.
  (There are two exceptions to the symmetry : Elements 384 and 512 are the
  
  negations of their mirror element ; for the fixed-point decoder, Q31(-x)
  
  does not equal -Q31(x). In order to keep the array exactly the same, the
  
  latter form has been used for these two elements.)
