• Access Haivision SRT statistics from ffmpeg command

  7 avril 2022, par martyn Gilbert

  I have been successfully using ffmpeg to stream using the Haivision SRT protocol enabled, I need to access the SRT statistics as described here https://github.com/Haivision/srt/blob/master/docs/API/statistics.md

  


  Can anyone help me to understand how to access these statistics from an ffmpeg commadline streaming SRT.

  


• Using FFMPEG and url_fopen example

  2 novembre 2012, par Blender

  I wonder how to get a stream from a URL (with url_fopen for example) (live video or PCM stream for example) and encode it into something ?

  Update :
  This actually was a mall formated question. It was about how to stream something out using url_fopen.

  Answer :
  It is quite simple :
  There is like a short article explaining how to use it
  And I had a small video streaming solution which actually used it and url_write called HelloVideoStreaming (windows sln) some many revisions ago.

  Good thing is that you actually do not really need or want to use ffmpeg for streaming. But you want to have sendable packets of encoded data in order to send. We have a client that does it (crossplatform, with premake project generation script). Main thing there is to use url_open_dyn_buf and url_close_dyn_buf which are shortly described here

• Anomalie #4598 (Fermé) : PHP 8 : Resource vs GdImage object problem.

  4 novembre 2020

  GD ne retourne plus une "resource", mais une instance de GdImage.

  Ça fait planter une partie des filtres images dans SPIP.
  Notamment s’il y a des tests avec is_resource()

  Exemple :
  

  Warning : Trying to access array offset on value of type bool in [...]ecrire/inc/filtres_images_lib_mini.php on line 1607 à 1610
  Qui provient de grosso modo :

  - La correction chez WP : https://core.trac.wordpress.org/ticket/50833

  Avec la solution proposée :

  Note that in PHP 7.2 and older, instanceOf operator requires an object. If you need to make your code function across PHP versions older than 7.3 through PHP 8.0, you will need an additional is_object() check :

  - if (is_resource($image))
  + if (is_resource($image) || (is_object($image) && $image instanceOf \GdImage))
