• rtpdec_jpeg : fix low contrast image on low quality setting

  rtpdec_jpeg : fix low contrast image on low quality setting
  The problem is that the argument ’q’ is of the type uint8_t.
  
  According to the JPEG standard, if 1 <= q <= 50, the scale factor
  
  ’S’ should be 5000 / Q. Because the create_default_qtables() reuses
  
  the variable ’q’ to store the result of this calculation, for small
  
  values of q < 19, q wil subsequently overflow and give wrong results
  
  in the calculated quantization tables.
  Instead, use a new variable ’S’ (same name as in RFC2435) with the
  
  proper range to store the result of the division.

• ffmpeg channels don't work (PHP)

  15 avril 2016, par Y.Saad

  I have a lot of channels with " ffmpeg " (4 channels) that start automatically, I create a code for show the first channel and after 5 seconds show the second .. Etc All things as right but I have a small problem the seconds channel doesn’t start automatically, I need to make stop to the first channel

  Code for 4 channel work 100% but without function for show first channel and after 5 seconds show the second ... Etc

  <?php

  What is the error : [tcp @ 0x55ce69425e00] Port missing in uri and where it comes from ?
May be an global configuration error and not ffmpeg ?
Thanks

  


  EDIT

  


  I found out, that it is working only with sudo and the actual ffmpeg version (static build) from the home directory of the user, which is owend by the user.
All privileges of the directory's are at the user.
