• Anomalie #3523 : Gestion des plugins avec spip 3.0.20

  5 août 2015, par Gilles VINCENT

  en ajoutant la directive
  

  opcache.validate_timestamps=0

  à ma config php, comme conseillé dans http://wiki.mikejung.biz/PHP_OPcache pour un serveur en production, la page de gestion des plugins refonctionne à nouveau correctement. De plus, la valeur
  

  opcache.revalidate_freq=60

  (valeur par défaut fournie lors de l’install) est vraiment longue.
  Si je commente cette ligne dans le fichier de config, le phpinfo() indique une valeur plus raisonnable de 2 seulement.
  Je pense que le chargement méga long venait de cette constante.

  La différence de comportement avec la config "pour développement" entre une 3.0.19 et une 3.0.20 reste encore surprenante.
  Si j’ai le temps, je creuserai dans une semaine à mon retour de vacance, car tout le monde ne peut as jouer avec ces paramètres du serveur... :/

• libavcodec/qsvdec_h2645.c : switch to the new BSF API

  libavcodec/qsvdec_h2645.c : switch to the new BSF API
  This patch applies same changes as commit e3dfef8e3c85a64dbe6388117303f5819fa3c6a2 of libav :
  
  instead of the obsolete AVBitStreamFilterContext now the new AVBSFContext filter is used to
  
  restore annex-B prefixes.

• Correct command to transmit audio to ip camera using ffmpeg ?

  4 novembre 2016, par the_naive

  So I found some hints in this discussion on the correct command to transmit audio to Axis IP camera through using ffmpeg in windows, but still I have not managed to successfully transmit audio to the camera.

  The command I’m using is the following :

  ffmpeg -v debug -y -re -f dshow -i "audio=Microphone (2- High Definition Audio Device)" -c:a pcm_mulaw -ac 1 -ar 16000 -b:a 128k -f flv http://oper
  
  ator:operator@10.10.210.2/axis-cgi/audio/transmit.cgi -multiple_requests 1 -reconnect_at_eof 1 -reconnect_streamed 1 -content_type "audio/basic" -report

  The ouput I get following this command is the following :

  ffmpeg started on 2016-11-04 at 17:32:13
  
  Report written to "ffmpeg-20161104-173213.log"

  For some reason, despite setting multiple_requests, reconnect_eof, reconnect_streamed all to true, connection becomes closed.

  Could you please tell me what I’m doing wrong ?
