• Anomalie #4342 (Fermé) : Erreur 1071 de mysql : Specified key was too long ; max key length is 1000 ...

  26 mai 2019

  Bonjour,

  Après avoir configuré MariaDB pour être en UTF8MB4, je n’ai pas pu installer un plugin (comme il y a aussi un bug SVP, je vais faire un autre ticket spécifique).
  Pour être précis, un table du plugin n’a pas été créée et sql.log contient :
  

  2019-05-25 16:23:59 78.205.175.37 (pid 16091) :Pri:ERREUR : Erreur 1071 de mysql : Specified key was too long ; max key length is 1000 bytes
  in ecrire/base/create.php L73 [sql_create(),creer_ou_upgrader_table(),alterer_base(),maj_tables(),serie_alter(),maj_while(),maj_plugin(),referer_spam_upgrade(),spip_plugin_install(),plugins_installer_dist(),installer_plugin(),do_install(),do_action(),one_action(),action_actionner_dist(),traiter_appels_actions()]
  CREATE  TABLE IF NOT EXISTS `mutu_pro2spipf126`.spip_referer_spam (
          date DATE NOT NULL,
          referer VARCHAR (255) ,
          PRIMARY KEY (referer)) ENGINE=MyISAM
  

  La documentation sur ce sujet est abondante.
  Ceci m’a semblé un bon résumé du problème : https://stackoverflow.com/questions/6172798/mysql-varchar255-utf8-is-too-long-for-key-but-max-length-is-1000-bytes
  Et la solution générale consiste à faire un index de seulement 191 : https://dev.mysql.com/doc/refman/5.7/en/charset-unicode-conversion.html :
  

  In an InnoDB table that uses COMPACT or REDUNDANT row format, these column and index definitions are legal :
  col1 VARCHAR(500) CHARACTER SET utf8, INDEX (col1(255))
  To use utf8mb4 instead, the index must be smaller :
  
  col1 VARCHAR(500) CHARACTER SET utf8mb4, INDEX (col1(191))
  

• FFMPEG shows bitrate=N/A and doesn't send anything

  20 mai 2019, par Mehul Jain

  I am trying to relay an stream from one rtsp url to another without recoding using this command :

  ffmpeg
 -rtsp_transport tcp
 -fflags nobuffer
 -re
 -i rtsp://xxx.xxx.xxx.xxx:554/[stream_name]
 -vcodec copy
 -an
 -f rtsp rtsp://yyy.yyy.yyy.yyy/[new_stream_name]

  But FFMPEG doesn’t stream anything and stats shows bitrate=N/A

  This is the exact output that i get :

  Although when i change output stream container to ’flv’ and protocol to ’rtmp’ it works.

  Any help will be appreciated.

  The nginx rtmp exec command not working on my macOS.
  I checked the error log file and saw this error.
