  why it comes like this native-lib.cpp:16: undefined reference av_register_all ?

  



  I added all the required libs in my jni folder . but, why this error and this native-lib.cpp:16 : undefined reference av_register_all comes ?

  



  How can I solve this ?

  


• avformat/utils : make av_url_split search for hashmark as well to separate hostname

  3 février 2020, par Marton Balint

  avformat/utils : make av_url_split search for hashmark as well to separate hostname
  RFC 3986 states that the generic syntax uses the slash ("/"), question mark
  
  (" ?"), and number sign ("#") characters to delimit components that are
  
  significant to the generic parser's hierarchical interpretation of an
  
  identifier.

• Evolution #4102 : Ordre des inclures dans cache/charger_plugins_options.php

  8 juillet 2019, par cam.lafit -

  Salut

  Ma solution n’est pas bonne non plus. On peut selon l’ordre d’appel devoir encapsuler le code d’un fichier options. Donc la solution de @placido est plus pertiente. Le patch suivant ne casse pas le comportement par défaut de SPIP et permet de charger avant un bout d’options.

  Soit le pluginA ayant besoin de surcharger les options de pluginB, si on fait pluginA/pre_pluginB_options.php alors l’ordre de chargement devrait être :

  • pluginA/pre_pluginB_options.php
  • pluginB/pluginB_options.php
  • pluginA/pluginA_options.php
